Method Detail

discards

public boolean discards(int index)

Overrides:

discards in class Expression

evaluateImpl

protected abstract void evaluateImpl(VMXState t)

evaluateVoidImpl

protected final void evaluateVoidImpl(VMXState t)

Overrides:

evaluateVoidImpl in class Expression

execute

public final AbruptCompletion.Return execute(VMXState s)

Description copied from interface: Routine

This callback method is invoked by the executing VMXState. A return value has to be wrapped in an instance of AbruptCompletion.Return.

Specified by:

execute in interface Routine

Parameters:

s - the executing VMXState

Returns:

the wrapped return value

getFrameSize

public int getFrameSize()

Description copied from interface: Routine

Computes the number of VMXState stack elements for the frame of this routine. This includes the parameters, if any.

Specified by:

getFrameSize in interface Routine

Returns:

the size of the frame in terms of stack elements

getJavaFrameSize

public int getJavaFrameSize()

Description copied from interface: Routine

Computes the number of VMXState stack elements for the Java frame of this routine. This includes the parameters, if any.

Specified by:

getJavaFrameSize in interface Routine

Returns:

the size of the Java frame in terms of stack elements

getParameterSize

public int getParameterSize()

Description copied from interface: Routine

Computes the number of VMXState stack elements for the parameters of this routine.

Specified by:

getParameterSize in interface Routine

Returns:

the number of stack elements for parameters

hasJavaParameters

public boolean hasJavaParameters()

Description copied from interface: Routine

Determines whether this routine expects its parameters on the Java frame or the normal frame.

Specified by:

hasJavaParameters in interface Routine

Returns:

true iff parameters are expected on the Java frame

setJFrameSize

public final void setJFrameSize(int jsize)

setParameterSize

public final void setParameterSize(int params)

writeFinally

public void writeFinally(de.grogra.xl.compiler.BytecodeWriter writer,
                         int label,
                         ControlTransfer cause)

Overrides:

writeFinally in class Expression
