- Detailed description

Edge pairs are used mainly in the context of the DRC functions (width_check, space_check etc.) of Region and Edges. A single edge pair represents two edges participating in a DRC violation. In the two-layer checks (inside, overlap) The first edge represents an edge from the first layer and the second edge an edge from the second layer. For single-layer checks (width, space) the order of the edges is arbitrary.

This class has been introduced in version 0.23.

## + |
This operator adds the edge pairs of the other collection to self and returns a new combined set. This method has been introduced in version 0.24. The 'join' alias has been introduced in version 0.28.12. | |||||

## += |
This operator adds the edge pairs of the other collection to self. This method has been introduced in version 0.24. Note that in Ruby, the '+=' operator actually does not exist, but is emulated by '+' followed by an assignment. This is less efficient than the in-place operation, so it is recommended to use 'join_with' instead. The 'join_with' alias has been introduced in version 0.28.12. | |||||

## [] |
This method returns nil if the index is out of range. It is available for flat edge pairs only - i.e. those for which has_valid_edge_pairs? is true. Use flatten to explicitly flatten an edge pair collection. The each iterator is the more general approach to access the edge pairs. | |||||

## _create |
Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created. | |||||

## _destroy |
Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | |||||

## _destroyed? |
This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | |||||

## _is_const_object? |
This method returns true, if self is a const reference. In that case, only const methods may be called on self. | |||||

## _manage |
After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||

## _unmanage |
Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur. Usually it's not required to call this method. It has been introduced in version 0.24. | |||||

## assign |
| |||||

## bbox |
The bounding box is the box enclosing all points of all edge pairs. | |||||

## clear |
| |||||

## count |
The count is computed 'as if flat', i.e. edge pairs inside a cell are multiplied by the number of times a cell is instantiated. Starting with version 0.27, the method is called 'count' for consistency with Region. 'size' is still provided as an alias.
| |||||

## create |

This method has been added in version 0.26. | |||||

## destroy |
Use of this method is deprecated. Use _destroy instead Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing. | |||||

## destroyed? |
Use of this method is deprecated. Use _destroyed? instead This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself. | |||||

## dup |
| |||||

## each |
| |||||

## edges |
| |||||

## enable_progress |
After calling this method, the edge pair collection will report the progress through a progress bar while expensive operations are running. The label is a text which is put in front of the progress bar. Using a progress bar will imply a performance penalty of a few percent typically. | |||||

## enable_properties |
This method has an effect mainly on original layers and will import properties from such layers. By default, properties are not enabled on original layers. Alternatively you can apply filter_properties or map_properties to enable properties with a specific name key. This method has been introduced in version 0.28.4. | |||||

## extents |
This method will return a region consisting of the bounding boxes of the edge pairs. The boxes will not be merged, so it is possible to determine overlaps of these boxes for example. | |||||

This method will return a region consisting of the bounding boxes of the edge pairs enlarged by the given distance d. The enlargement is specified per edge, i.e the width and height will be increased by 2*d. The boxes will not be merged, so it is possible to determine overlaps of these boxes for example. | ||||||

This method will return a region consisting of the bounding boxes of the edge pairs enlarged by the given distance dx in x direction and dy in y direction. The enlargement is specified per edge, i.e the width will be increased by 2*dx. The boxes will not be merged, so it is possible to determine overlaps of these boxes for example. | ||||||

## filter |
See EdgePairFilter for a description of this feature. This method has been introduced in version 0.29. | |||||

## filter_properties |
Calling this method on a container will reduce the properties to values with name keys from the 'keys' list. As a side effect, this method enables properties on original layers. This method has been introduced in version 0.28.4. | |||||

## has_valid_edge_pairs? |
This method has been introduced in version 0.26. | |||||

## insert |
| |||||

| ||||||

This method has been introduced in version 0.25. | ||||||

## insert_into |

This is less efficient than the in-place operation, so it is recommended to use 'join_with' instead. The 'join_with' alias has been introduced in version 0.28.12. | |||||

## map_properties |
Calling this method on a container will reduce the properties to values with name keys from the 'keys' hash and renames the properties. Properties not listed in the key map will be removed. As a side effect, this method enables properties on original layers. This method has been introduced in version 0.28.4. | |||||

## move |
Moves the edge pairs by the given offset and returns the moved edge pair collection. The edge pair collection is overwritten. Starting with version 0.25 the displacement is of vector type. | |||||

This method creates polygons from the edge pairs. Each polygon will be a triangle or quadrangle which connects the start and end points of the edges forming the edge pair. This version allows one to specify an enlargement which is applied to the edges. The length of the edges is modified by applying the enlargement and the edges are shifted by the enlargement.

This method behaves like with_angle, but angles are always positive - i.e. there is no differentiation between edges sloping 'down' vs. edges sloping 'up. This method has been added in version 0.29.1. | ||||||

## with_abs_angle_both |

## with_angle |
Filters the edge pairs in the edge pair collection by orientation. If "inverse" is false, only edge pairs with at least one edge having the given angle to the x-axis are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. This will filter edge pairs with at least one horizontal edge: horizontal = edge_pairs.with_angle(0, false) Note that the inverse result = edge_pairs.with_angle(0, false) others = edge_pairs.with_angle_both(0, true) This method has been added in version 0.27.1. | |||||

Filters the edge pairs in the edge pair collection by orientation. If "inverse" is false, only edge pairs with at least one edge having an angle between min_angle and max_angle are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. With "include_min_angle" set to true (the default), the minimum angle is included in the criterion while with false, the minimum angle itself is not included. Same for "include_max_angle" where the default is false, meaning the maximum angle is not included in the range. Note that the inverse result = edge_pairs.with_angle(0, 45, false) others = edge_pairs.with_angle_both(0, 45, true) This method has been added in version 0.27.1. | ||||||

Filters the edge pairs in the edge pair collection by orientation. If "inverse" is false, only edge pairs with at least one edge having an angle of the given type are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. This version allows specifying an edge type instead of an angle. Edge types include multiple distinct orientations and are specified using one of the Edges#OrthoEdges, Edges#DiagonalEdges or Edges#OrthoDiagonalEdges types.

This will filter edge pairs with at least one horizontal edge: horizontal = edge_pairs.with_angle_both(0, false) Note that the inverse result = edge_pairs.with_angle_both(0, false) others = edge_pairs.with_angle(0, true) This method has been added in version 0.27.1. | |||||

Filters the edge pairs in the edge pair collection by orientation. If "inverse" is false, only edge pairs with both edges having an angle between min_angle and max_angle are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. With "include_min_angle" set to true (the default), the minimum angle is included in the criterion while with false, the minimum angle itself is not included. Same for "include_max_angle" where the default is false, meaning the maximum angle is not included in the range. Note that the inverse result = edge_pairs.with_angle_both(0, 45, false) others = edge_pairs.with_angle(0, 45, true) This method has been added in version 0.27.1. | ||||||

Filters the edge pairs in the edge pair collection by orientation. If "inverse" is false, only edge pairs with both edges having an angle of the given type are returned. If "inverse" is true, edge pairs not fulfilling this criterion for both edges are returned. This version allows specifying an edge type instead of an angle. Edge types include multiple distinct orientations and are specified using one of the Edges#OrthoEdges, Edges#DiagonalEdges or Edges#OrthoDiagonalEdges types. Note that the inverse result = edge_pairs.with_angle_both(RBA::Edges::Ortho, false) others = edge_pairs.with_angle(RBA::Edges::Ortho, true) This method has been added in version 0.28. | ||||||

## with_area |
Filters the edge pairs in the edge pair collection by enclosed area. If "inverse" is false, only edge pairs with the given area are returned. If "inverse" is true, edge pairs not with the given area are returned. This method has been added in version 0.27.2. | |||||

Filters the edge pairs in the edge pair collection by enclosed area. If "inverse" is false, only edge pairs with an area between min_area and max_area (max_area itself is excluded) are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. This method has been added in version 0.27.2. | ||||||

## with_distance |
Filters the edge pairs in the edge pair collection by distance of the edges. If "inverse" is false, only edge pairs where both edges have the given distance are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. Distance is measured as the shortest distance between any of the points on the edges. This method has been added in version 0.27.1. | |||||

Filters the edge pairs in the edge pair collection by distance of the edges. If "inverse" is false, only edge pairs where both edges have a distance between min_distance and max_distance (max_distance itself is excluded) are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. Distance is measured as the shortest distance between any of the points on the edges. This method has been added in version 0.27.1. | ||||||

## with_internal_angle |
Filters the edge pairs in the edge pair collection by the angle between their edges. If "inverse" is false, only edge pairs with the given angle are returned. If "inverse" is true, edge pairs not with the given angle are returned. The angle is measured between the two edges. It is between 0 (parallel or anti-parallel edges) and 90 degree (perpendicular edges). This method has been added in version 0.27.2. | |||||

## with_length |
Filters the edge pairs in the edge pair collection by length of at least one of their edges. If "inverse" is false, only edge pairs with at least one edge having the given length are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. This method has been added in version 0.27.1. | |||||

Filters the edge pairs in the edge pair collection by length of at least one of their edges. If "inverse" is false, only edge pairs with at least one edge having a length between min_length and max_length (excluding max_length itself) are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. If you don't want to specify a lower or upper limit, pass nil to that parameter. This method has been added in version 0.27.1. | ||||||

## with_length_both |
Filters the edge pairs in the edge pair collection by length of both of their edges. If "inverse" is false, only edge pairs where both edges have the given length are returned. If "inverse" is true, edge pairs not fulfilling this criterion are returned. This method has been added in version 0.27.1. | |||||

Filters the edge pairs in the edge pair collection by length of both of their edges.
