API reference - Class DEdge

Notation used in Ruby API documentation

Module: db

Description: An edge class

An edge is a connection between points, usually participating in a larger context such as a polygon. An edge has a defined direction (from p1 to p2). Edges play a role in the database as parts of polygons and to describe a line through both points. The Edge object is also used inside the boolean processor (EdgeProcessor). Although supported, edges are rarely used as individual database objects.

See The Database API for more details about the database objects like the Edge class.

Detailed description

!=

Signature: [const] bool != (const DEdge e)

Description: Inequality test

e:The object to compare against

*

Signature: [const] DEdge * (double scale_factor)

Description: Scale edge

scale_factor:The scaling factor
Returns:The scaled edge

The * operator scales self with the given factor.

This method has been introduced in version 0.22.

Python specific notes:
This method also implements '__rmul__'.

<

Signature: [const] bool < (const DEdge e)

Description: Less operator

e:The object to compare against
Returns:True, if the edge is 'less' as the other edge with respect to first and second point

==

Signature: [const] bool == (const DEdge e)

Description: Equality test

e:The object to compare against

_const_cast

Signature: [const] DEdge ptr _const_cast

Description: Returns a non-const reference to self.

Basically, this method allows turning a const object reference to a non-const one. This method is provided as last resort to remove the constness from an object. Usually there is a good reason for a const object reference, so using this method may have undesired side effects.

This method has been introduced in version 0.29.6.

_create

Signature: void _create

Description: Ensures the C++ object is created

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

Signature: void _destroy

Description: Explicitly destroys the object

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?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already 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?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

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

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

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

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

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

Signature: void assign (const DEdge other)

Description: Assigns another object to self

bbox

Signature: [const] DBox bbox

Description: Return the bounding box of the edge.

clipped

Signature: [const] variant clipped (const DBox box)

Description: Returns the edge clipped at the given box

This method has been introduced in version 0.26.2.

clipped_line

Signature: [const] variant clipped_line (const DBox box)

Description: Returns the line through the edge clipped at the given box

box:The clip box.
Returns:The part of the line through the box or nil if the line does not intersect with the box.

In contrast to clipped, this method will consider the edge extended infinitely (a "line"). The returned edge will be the part of this line going through the box.

This method has been introduced in version 0.26.2.

coincident?

Signature: [const] bool coincident? (const DEdge e)

Description: Coincidence check.

e:the edge to test with
Returns:True if the edges are coincident.

Checks whether a edge is coincident with another edge. Coincidence is defined by being parallel and that at least one point of one edge is on the other edge.

contains?

Signature: [const] bool contains? (const DPoint p)

Description: Tests whether a point is on an edge.

p:The point to test with the edge.
Returns:True if the point is on the edge.

A point is on a edge if it is on (or at least closer than a grid point to) the edge.

contains_excl?

Signature: [const] bool contains_excl? (const DPoint p)

Description: Tests whether a point is on an edge excluding the endpoints.

p:The point to test with the edge.
Returns:True if the point is on the edge but not equal p1 or p2.

A point is on a edge if it is on (or at least closer than a grid point to) the edge.

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

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.

crossed_by?

Signature: [const] bool crossed_by? (const DEdge e)

Description: Checks, if the line given by self is crossed by the edge e

e:The edge representing the line that the edge must be crossing.

self if considered an infinite line. This predicate renders true if the edge e is cut by this line. In other words: this method returns true if e.p1 is in one semispace of self while e.p2 is in the other or one of them is exactly on self.

crossing_point

Signature: [const] DPoint crossing_point (const DEdge e)

Description: Returns the crossing point on two edges.

e:The edge representing the line that self must be crossing.
Returns:The point where self crosses the line given by "e".

This method delivers the point where the given line (self) crosses the edge given by the argument "e". self is considered infinitely long and is required to cut through the edge "e". If self does not cut this line, the result is undefined. See crossed_by? for a description of the crossing predicate.

This method has been introduced in version 0.19.

cut_point

Signature: [const] variant cut_point (const DEdge e)

Description: Returns the intersection point of the lines through the two edges.

e:The edge to test.
Returns:The point where the lines intersect.

This method delivers the intersection point between the lines through the two edges. If the lines are parallel and do not intersect, the result will be nil. In contrast to intersection_point, this method will regard the edges as infinitely extended and intersection is not confined to the edge span.

This method has been introduced in version 0.27.1.

d

Signature: [const] DVector d

Description: Gets the edge extension as a vector.

This method is equivalent to p2 - p1. This method has been introduced in version 0.26.2.

destroy

Signature: void destroy

Description: Explicitly destroys the object

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?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already 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.

distance

Signature: [const] double distance (const DPoint p)

Description: Gets the distance of the point from the line through the edge.

p:The point to test.
Returns:The distance

Returns the distance between the edge and the point. The distance is signed which is negative if the point is to the "right" of the edge and positive if the point is to the "left". The distance is measured by projecting the point onto the line through the edge. If the edge is degenerated, the distance is not defined.

This method considers the edge to define an infinite line running through it. distance returns the distance of 'p' to this line. A similar method is euclidian_distance, but the latter regards the edge a finite set of points between the endpoints.

Description: Absolute distance between the edge and a point.

p:The point to test.
Returns:The distance

Returns the distance between the edge and the point.

Signature: double euclidian_distance (const DPoint p)

Description: Gets the distance of the point from the the edge.

p:The point to test.
Returns:The distance

Signature: DEdge extend (double d)

Description: Extends the edge (modifies self)

d:The distance by which to shift the end points.
Returns:The extended edge (self).
