Examples of org.apache.bcel.classfile.ConstantValue

org.apache.bcel.classfile.ConstantValue
This class is derived from Attribute and represents a constant value, i.e., a default value for initializing a class field. This class is instantiated by the Attribute.readAttribute() method. @version $Id: ConstantValue.java 386056 2006-03-15 11:31:56Z tcurdt $ @author M. Dahm @see Attribute
