Method Detail

createNodeSplitCopy

public DFAStateNode createNodeSplitCopy(short copyID)

Description copied from class: DFAAbstractStateNode

Creates a copy of this state node, where all attributes are copied shallowly, except for the DFAAbstractStateNode.successors array, which is deep-copied, and the node ID, which is replaced by the parameter copyID. Used by DFANodeSplit.

Overrides:

createNodeSplitCopy in class BackwardDFAStateNode

Parameters:

copyID - new ID for the copy.

Returns:

an "almost shallow" copy of this node.
