Class JVMClass<T extends IClassLoader>

java.lang.Object

com.ibm.wala.classLoader.BytecodeClass<T>

com.ibm.wala.classLoader.JVMClass<T>

Type Parameters:

T - type of classloader which loads this format of class.

All Implemented Interfaces:

IClass, IClassHierarchyDweller

Direct Known Subclasses:

ShrikeClass

public abstract class JVMClass<T extends IClassLoader>
extends BytecodeClass<T>

Note that classes from JVML have some features that are not present in all "bytecode" languages currently supported.
