Detailed Description

Supporting class from copy mechanism within ROSE.

This class forms a base class for the SgShallowCopy and SgTreeCopy classes to support the control of copying of subtrees (what IR nodes are copied by a deep or shallow copy).

To tailor a specific type of copy operation derive a class from this abstract class and define the clone_node function as required. context information if required muyst be obtained through local analysis inside the function using the parent or scope information at each IR node.

Note:

This is an abstract class.

For internal use only.

Used in ROSETTA generated copy functions on each IR node. The location of this code should perhaps be changed to be in the generate copy code rather than Node.code in ROSETTA/Grammar.

Private Attributes
int	depth
	This data member records the depth of the traversal (root node == 0).
copiedNodeMapType	copiedNodeMap
	This is internal state used to asscociate pairs of IR nodes copied instead of shared.
