copy

public abstract TreeNode copy()

Creates a copy of this node.

Returns:

a copy of this node

set

public TreeNode set(TreeNode other)

Parameters:

other - the other node

Returns:

this node

getLineNumber

public int getLineNumber()

Retreives the line number from which this node came.

Returns:

the line number

dump

public abstract void dump(java.io.PrintStream out,
                          int n)

Pretty-prints this node to this output stream.

Parameters:

out - the output stream

copy_Boolean

protected java.lang.Boolean copy_Boolean(java.lang.Boolean b)

Copies a boolean value. This method is used internally by the generated AST classes

copy_AbstractSymbol

protected AbstractSymbol copy_AbstractSymbol(AbstractSymbol sym)

Copies an AbstractSymbol value. This method is used internally by the generated AST classes

dump_Boolean

protected void dump_Boolean(java.io.PrintStream out,

                            java.lang.Boolean b)

Dumps a printable representation of a boolean value. This method is used internally by the generated AST classes

dump_AbstractSymbol

protected void dump_AbstractSymbol(java.io.PrintStream out,
                                   int n,
                                   AbstractSymbol sym)

Dumps a printable representation of an AbstactSymbol value. This method is used internally by the generated AST classes

dump_line

protected void dump_line(java.io.PrintStream out,
                         int n)

Dumps a printable representation of current line number This method is used internally by the generated AST classes
