API reference - Class ZeroDistanceMode

Notation used in Ruby API documentation

Module: db

Description: This class represents the zero_distance_mode type for \Region#width and related checks.

This mode determines how edges with zero distance are treated in the DRC checks. Formally these edges do neither represent a space other other relation as they do not face each other. There are three modes available to treat this boundary case: Ignore such edges (NeverIncludeZeroDistance) or only include them if they share at least one common point (IncludeZeroDistanceWhenTouching). The latter mode allows activating checks for the 'kissing corner' case and is the default mode in most checks. This enum has been introduced in version 0.28.16.

Public constructors

Detailed description

!=

(1) Signature: [const] bool != (const ZeroDistanceMode other)

(2) Signature: [const] bool != (int other)

Description: Compares an enum with an integer for inequality

<

(1) Signature: [const] bool < (const ZeroDistanceMode other)

Description: Returns true if the first enum is less (in the enum symbol order) than the second

(2) Signature: [const] bool < (int other)

Description: Returns true if the enum is less (in the enum symbol order) than the integer value

(1) Signature: [const] bool == (const ZeroDistanceMode other)

Description: Compares two enums

(2) Signature: [const] bool == (int other)

Description: Compares an enum with an integer value

IncludeZeroDistanceWhenCollinearAndTouching

Signature: [static,const] ZeroDistanceMode IncludeZeroDistanceWhenCollinearAndTouching

Description: Specifies that check functions should include edges when they are collinear and touch

With this specification, the check functions will also check edges if they share at least one common point and are collinear. This is the mode that includes checking the 'kissing corner' cases when the kissing edges are collinear. This mode was default up to version 0.28.

Python specific notes:
The object exposes a readable attribute 'IncludeZeroDistanceWhenCollinearAndTouching'. This is the getter.

IncludeZeroDistanceWhenOverlapping

Signature: [static,const] ZeroDistanceMode IncludeZeroDistanceWhenOverlapping

Description: Specifies that check functions should include edges when they overlap

With this specification, the check functions will also check edges which are collinear and share more than a single point. This is the mode that excludes the 'kissing corner' cases.

Python specific notes:
The object exposes a readable attribute 'IncludeZeroDistanceWhenOverlapping'. This is the getter.

IncludeZeroDistanceWhenTouching

Signature: [static,const] ZeroDistanceMode IncludeZeroDistanceWhenTouching

Description: Specifies that check functions should include edges when they touch

With this specification, the check functions will also check edges if they share at least one common point. This is the mode that includes checking the 'kissing corner' cases. This mode is default for version 0.28.16 and later.

Python specific notes:
The object exposes a readable attribute 'IncludeZeroDistanceWhenTouching'. This is the getter.

NeverIncludeZeroDistance

Signature: [static,const] ZeroDistanceMode NeverIncludeZeroDistance

Description: Specifies that check functions should never include edges with zero distance.

With this specification, the check functions will ignore edges which are collinear or touch.

Python specific notes:
The object exposes a readable attribute 'NeverIncludeZeroDistance'. This is the getter.

_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 ZeroDistanceMode other)

Description: Assigns another object to self

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.

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.

dup

Signature: [const] new ZeroDistanceMode ptr dup

Description: Creates a copy of self

Python specific notes:
This method also implements '__copy__' and '__deepcopy__'.

hash

Signature: [const] int hash

Description: Gets the hash value from the enum

This method is also available as 'hash(object)'.

inspect

Python specific notes:
This method is also available as 'repr(object)'.

is_const_object?

Signature: [const] bool is_const_object?

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

Use of this method is deprecated. Use _is_const_object? instead

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

new

(1) Signature: [static] new ZeroDistanceMode ptr new (int i)

Description: Creates an enum from a string value

Python specific notes:
This method is the default initializer of the object.
