Detailed description

SquareCounting

Signature: [static,const] Algorithm SquareCounting

Description: Specifies the square counting algorithm for RExtractorTechConductor#algorithm.

See RExtractor#square_counting_extractor for more details.

Python specific notes:
The class exposes a readable attribute 'SquareCounting'. This is the getter.

Tesselation

Signature: [static,const] Algorithm Tesselation

Description: Specifies the square counting algorithm for RExtractorTechConductor#algorithm.

See RExtractor#tesselation_extractor for more details.

Python specific notes:
The class exposes a readable attribute 'Tesselation'. This is the getter.

_const_cast

Signature: [const] RExtractorTechConductor 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.

algorithm

Signature: [const] Algorithm algorithm

Description: Gets the algorithm to use

Specifies the algorithm to use. The default algorithm is 'SquareCounting'.

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

algorithm=

Signature: void algorithm= (Algorithm d)

Description: Sets the algorithm to use

See algorithm for a description of this attribute.

Python specific notes:
The object exposes a writable attribute 'algorithm'. This is the setter.

assign

Signature: void assign (const RExtractorTechConductor 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 RExtractorTechConductor ptr dup

Description: Creates a copy of self

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

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.

layer

Signature: [const] unsigned int layer

Description: Gets the layer index

The layer index is a generic identifier for the layer. It is the value used as key in the geometry and port arguments of RNetExtractor#extract. This attribute specifies the layer the conductor is on.

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

layer=

Signature: void layer= (unsigned int l)

Description: Sets the layer index

See layer for a description of this attribute.

Python specific notes:
The object exposes a writable attribute 'layer'. This is the setter.

new

Signature: [static] new RExtractorTechConductor ptr new

Description: Creates a new object of this class

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

resistance

Signature: [const] double resistance

Description: Gets the sheet resistance value of the conductor layer

This value specifies the cond resistance in Ohm per square. The actual resistance is obtained by multiplying this value with the number of squares.

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

resistance=

Signature: void resistance= (double r)

Description: Sets the sheet resistance value of the conductor layer

See resistance for a description of this attribute.

Python specific notes:
The object exposes a writable attribute 'resistance'. This is the setter.

to_s

Signature: [const] string to_s

Description: Returns a string describing this object

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

triangulation_max_area

Signature: [const] double triangulation_max_area

Description: Gets the triangulation 'max_area' parameter

This parameter is used for the 'Tesselation' algorithm and specifies the maximum area of the triangles in square micrometers.

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

triangulation_max_area=

Signature: void triangulation_max_area= (double max_area)

Description: Sets the triangulation 'max_area' parameter

The object exposes a writable attribute 'triangulation_max_area'. This is the setter.

triangulation_min_b

Signature: [const] double triangulation_min_b

Description: Gets the triangulation 'min_b' parameter

This parameter is used for the 'Tesselation' algorithm and specifies the shortest edge to circle radius ratio of the Delaunay triangulation.

triangulation_min_b=

Signature: void triangulation_min_b= (double min_b)

Description: Sets the triangulation 'min_b' parameter

See triangulation_min_b for a description of this attribute.
