Class RdbReference (version 0.20)

Description: A cell reference

This class describes a cell reference. Such reference object can be attached to cells to describe instantiations of them in parent cells. Not necessarily all instantiations of a cell in the layout database are represented by references and in some cases there might even be no references at all. The references are merely a hint how a marker must be displayed in the context of any other, potentially parent, cell in the layout database.

Method Overview

[static] RdbReference new( DCplxTrans trans, unsigned int parent_cell_id )Create a reference with a given transformation and parent cell ID
[const] const ref DCplxTrans transGets the transformation for this reference
trans=( DCplxTrans trans )Sets the transformation for this reference
[const] unsigned int parent_cell_idGets parent cell ID for this reference
parent_cell_id=( unsigned int id )Sets the parent cell ID for this reference
assign( RdbReference other )Assign the contents of another object to self
[const] RdbReference dupCreates a copy of self.
destroyExplicitly destroy the object
[const] bool destroyedTell, if the object was destroyed

assign( RdbReference other )

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

destroy

Description: Explicitly destroy the object

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

[const] bool destroyed

Description: Tell, if the object was 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.

[const] RdbReference dup

Description: Creates a copy of self.

[static] RdbReference new( DCplxTrans trans, unsigned int parent_cell_id )

Description: Create a reference with a given transformation and parent cell ID

[const] unsigned int parent_cell_id

Description: Gets parent cell ID for this reference

returns:The parent cell ID

parent_cell_id=( unsigned int id )

Description: Sets the parent cell ID for this reference

[const] const ref DCplxTrans trans

Description: Gets the transformation for this reference

The transformation describes the transformation of the child cell into the parent cell. In that sense that is the usual transformation of a cell reference.

returns:The transformation

trans=( DCplxTrans trans )

Description: Sets the transformation for this reference
