Method Detail

variableExp

public boolean variableExp()

Description copied from class: ExpressionNode

Determines if the expression is an access to a local or a formal param. Redefined in the VariableExpNode class.

Overrides:

variableExp in class ExpressionNode

Returns:

a boolean value

translate

public void translate(org.apache.bcel.generic.ClassGen classGen,
                      org.apache.bcel.generic.MethodGen methodGen)

Description copied from class: ExpressionNode

Describe translate method here.

Overrides:

translate in class ExpressionNode

Parameters:

classGen - a ClassGen value

methodGen - a MethodGen value

translateSynthesized

public org.apache.bcel.generic.BranchHandle translateSynthesized(org.apache.bcel.generic.ClassGen classGen,
                                                                 org.apache.bcel.generic.MethodGen methodGen)

Description copied from class: ExpressionNode

First translate the expression and then synthesize it. This method is redefined in those expressions that already synthesize their result to avoid synthesize, de-synthesize, synthesize sequences.

Overrides:

translateSynthesized in class ExpressionNode

Parameters:

classGen - a ClassGen value

methodGen - a MethodGen value

Returns:

a BranchHandle value
