objectFieldOffset

public final long objectFieldOffset(Field field)

Returns an unspecified, abstract "offset" of the passed Field to specify a generic access of the field's value for an instance of its declaring class that can be used with object-based methods like MemoryAccessor.set_int(Object,long,int). Whether that offset is an actual low-level memory offset relative to an instance' field offset base or simply an index of the passed field in its declaring class' list of fields, is implementation-specific.

Parameters:

field - the Field whose abstract offset shall be determined.

Returns:

the passed Field's abstract offset.
