Description: A net element for the NetTracer net tracing facility
This object represents a piece of a net extracted by the net tracer. See the description of NetTracer for more details about the net tracer feature.
The NetTracer object represents one shape of the net. The shape can be an original shape or a shape derived in a boolean operation. In the first case, the shape refers to a shape within a cell or a subcell of the original top cell. In the latter case, the shape is a synthesized one and outside the original layout hierarchy.
In any case, the shape method will deliver the shape and trans the transformation of the shape into the original top cell. To obtain a flat representation of the net, the shapes need to be transformed by this transformation.
layer will give the layer the shape is located at, cell_index will denote the cell that contains the shape.
This class has been introduced in version 0.25.

_const_cast | Signature: [const] NetElement 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 NetElement other) Description: Assigns another object to self |
bbox | Signature: [const] Box bbox Description: Delivers the bounding box of the shape as seen from the original top cell |
cell_index | Signature: [const] unsigned int cell_index Description: Gets the index of the cell the shape is inside |
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 NetElement ptr dup Description: Creates a copy of self Python specific notes: |
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 index of the layer the shape is on |
new | Signature: [static] new NetElement ptr new Description: Creates a new object of this class Python specific notes: |
shape | Signature: [const] Shape shape Description: Gets the shape that makes up this net element See the class description for more details about this attribute. |
trans | Signature: [const] ICplxTrans trans Description: Gets the transformation to apply for rendering the shape in the original top cell See the class description for more details about this attribute. |
