This abstract class provides a logic of a loading JavaClass objects class names via ClassPath.

Subclasses can choose caching strategy of the objects by implementing the abstract methods (e.g., storeClass(JavaClass) and findClass(String)).

public JavaClass loadClass(final Class<?> clazz) throws ClassNotFoundException

Implements org.apache.bcel.util.Repository.loadClass.

Finds the JavaClass object for a runtime Class object. If a class with the same name is already in this Repository, the Repository version is returned. Otherwise, getResourceAsStream() is called on the Class object to find the class's representation. If the representation is found, it is added to the Repository.

Parameters
clazz:Class<?>

the runtime Class object

Returns:JavaClass

JavaClass object for given runtime class

Annotations

Exceptions
ClassNotFoundException:
if the class is not in the Repository, and its representation could not be found
