get

public T get()

Description copied from class: Location

Get the current value of this location.

Specified by:

get in class Location<T>

get

public T get(T defaultValue)

Overrides:

get in class ClassMemberLocation<T>

set

public void set(Object newValue)

Overrides:

set in class ClassMemberLocation<T>

setWithSave

Overrides:

setRestore in class Location<T>

Parameters:

oldValue - the return value from a prior setWithSave.

isConstant

public boolean isConstant()

Overrides:

isConstant in class ClassMemberLocation<T>

isBound

public boolean isBound()

Overrides:

isBound in class ClassMemberLocation<T>

make

public static FieldLocation make(Object instance,
                                 Declaration decl)

make
