UnaryExpression

public UnaryExpression(java.lang.String op,
                       Expression base)

constructs binary expression from op and base

Parameters:

op - the name of the operation used for printing

base - the operand

Method Detail

getBase

public Expression getBase()

Returns base expression

Returns:

the base expression

printCore

public void printCore(java.io.PrintWriter out)

Prints text representation of tree on out (without new line termination).

Specified by:

printCore in interface AST

Specified by:

printCore in class ASTBase

Parameters:

out - the stream on which the text is written

instantiate

public Expression instantiate()

return copy of AST with value references instantiated by the substitutions set in the corresponding declaration identifiers

Returns:

the instantiated copy

accept

public AST accept(ASTVisitor visitor)

Accept visitor for a visit.

Parameters:

visitor - the visitor who is accepted by this node.

Returns:

the result of the visit (may be null).
