public abstract Class Repository

extends Object
Class Inheritance
Imports
java.io.IOException, org.apache.bcel.classfile.JavaClass, org.apache.bcel.util.ClassPath, .SyntheticRepository
The repository maintains informations about class interdependencies, e.g., whether a class is a sub-class of another. Delegates actual class loading to SyntheticRepository with current class path by default.
