Method Detail

displayParseTree

public void displayParseTree(ASTPtRootNode root)

parseTreeToExpression

public java.lang.String parseTreeToExpression(ASTPtRootNode root)
                                       throws IllegalActionException

Produce an expression for this parse tree.

Parameters:

root - The root of the parse tree.

Returns:

The expression.

Throws:

IllegalActionException - If the parse tree has an error.

printParseTree

public java.lang.String printParseTree(ASTPtRootNode root)

Return an expression for this parse tree, or a description of the exception if an exception occurs.

Parameters:

root - The root of the parse tree.

Returns:

The expression.

setStringMode

public void setStringMode(boolean stringMode)

Specify whether the expression to write is in string mode. FIXME string mode has only been implemented for leaf and sum nodes.

Parameters:

stringMode - True to put the expression to write in string mode.
