Interface GraphLoader

All Known Implementing Classes:

CFGLoader

public interface GraphLoader

This interface defines the contract for classes that provide the service of loading graphs built from Java classes.

Classes implementing this interface should provide some means of storing what class is being operated on, so that object instantiations can be kept to a minimum.
