Method Summary

Modifier and Type	Method and Description
void	initASTMapping(Object fromAstNode, CSTNode cstNode, Object toAstNode) Initialize the asymmetric mapping of an object (typically an astNode) to its originating cstNode, and of a cstNode to its consequent object (typically an astNode) so that AST-based analysis may report error messages exploiting the CST context, or to support incremental AST/CST update.

Method Detail

initASTMapping

void initASTMapping(Object fromAstNode,
                    CSTNode cstNode,
                    Object toAstNode)

Initialize the asymmetric mapping of an object (typically an astNode) to its originating cstNode, and of a cstNode to its consequent object (typically an astNode) so that AST-based analysis may report error messages exploiting the CST context, or to support incremental AST/CST update. Any pre-existing mapping is preserved. Each mapping involving a null object is ignored, so that for instance the toAstNode may be set null to establish only the fromAstNode to cstNode mapping.

Parameters:

fromAstNode - source of the AST-to-CST mapping

cstNode - target of the AST-to-CST mapping and source of the CST-to-AST mapping

toAstNode - target of the CST-to-AST mapping
