Method Summary

Modifier and Type	Method and Description
int	getEndPos(JCTree tree) This method will return the end position of a given tree, otherwise a Positions.NOPOS will be returned.
int	replaceTree(JCTree oldtree, JCTree newtree) Give an old tree and a new tree, the old tree will be replaced with the new tree, the position of the new tree will be that of the old tree.
void	storeEnd(JCTree tree, int endpos) Store ending position for a tree, the value of which is the greater of last error position and the given ending position.

Method Detail

getEndPos

int getEndPos(JCTree tree)

This method will return the end position of a given tree, otherwise a Positions.NOPOS will be returned.

Parameters:

tree - JCTree

Returns:

position of the source tree or Positions.NOPOS for non-existent mapping

storeEnd

void storeEnd(JCTree tree,
              int endpos)

Store ending position for a tree, the value of which is the greater of last error position and the given ending position.

Parameters:

tree - The tree.

endpos - The ending position to associate with the tree.

replaceTree

int replaceTree(JCTree oldtree,
                JCTree newtree)

Give an old tree and a new tree, the old tree will be replaced with the new tree, the position of the new tree will be that of the old tree.

Parameters:

oldtree - a JCTree to be replaced

newtree - a JCTree to be replaced with

Returns:

position of the old tree or Positions.NOPOS for non-existent mapping
