Class Repository

java.lang.Object

org.aspectj.apache.bcel.Repository

public abstract class Repository
extends Object

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.
