Constructor Detail

Java.Crement

public Java.Crement(Scanner.Location location,
                    java.lang.String operator,
                    Java.Lvalue operand)

Java.Crement

public Java.Crement(Scanner.Location location,
                    Java.Lvalue operand,
                    java.lang.String operator)

Method Detail

getType

public IClass getType()
               throws Java.CompileException

Overrides:

getType in class Java.Atom

compile

public void compile()
             throws Java.CompileException

Description copied from class: Java.Rvalue

Some Java.Rvalues compile more efficiently when their value is not needed, e.g. "i++".

Overrides:

compile in class Java.Rvalue

compileGet

public IClass compileGet()
                  throws Java.CompileException

Description copied from class: Java.Rvalue

Generates code that determines the value of the Java.Rvalue and puts it on the operand stack. This method relies on that the "context" of the Java.Rvalue is on top of the operand stack (see Java.Rvalue.compileContext()).

Overrides:

compileGet in class Java.Rvalue

Following copied from class: net.janino.Java.Rvalue

Returns:

The type of the Java.Rvalue
