org.apache.commons.compress.harmony.unpack200.bytecode.forms.ReferenceForm

org.apache.commons.compress.harmony.unpack200.bytecode.forms.SingleByteReferenceForm

Direct Known Subclasses:

FloatRefForm, IntRefForm, StringRefForm

public abstract class SingleByteReferenceForm
extends ReferenceForm

Some bytecodes (such as (a)ldc, fldc and ildc) have single-byte references to the class pool. This class is the abstract superclass of those classes.
