public class SyntheticRepository extends java.lang.Object implements Repository
This repository is used in situations where a Class is created outside the realm of a ClassLoader. Classes are loaded from the file systems using the paths specified in the given class path. By default, this is the value returned by ClassPath.getClassPath().
It is designed to be used as a singleton, however it can also be used with custom classpaths.- See Also:

storeClass
public void storeClass(JavaClass clazz)
Store a new JavaClass instance into this Repository.- Specified by:
storeClass
in interfaceRepository
-
removeClass
public void removeClass(JavaClass clazz)
Remove class from repository- Specified by:
removeClass
in interfaceRepository
-
findClass
public JavaClass findClass(java.lang.String className)
Find an already defined (cached) JavaClass object by name.- Specified by:
findClass
in interfaceRepository
-
loadClass
public JavaClass loadClass(java.lang.String className) throws java.lang.ClassNotFoundException
Find a JavaClass object by name. If it is already in this Repository, the Repository version is returned. Otherwise, the Repository's classpath is searched for the class (and it is added to the Repository if found).- Specified by:
loadClass
in interfaceRepository
- Parameters:
className
- the name of the class- Returns:
- the JavaClass object
- Throws:
java.lang.ClassNotFoundException
- if the class is not in the Repository, and could not be found on the classpath
-
loadClass
public JavaClass loadClass(java.lang.Class<?> clazz) throws java.lang.ClassNotFoundException
Find 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.- Specified by:
loadClass
in interfaceRepository
- Parameters:
clazz
- the runtime Class object- Returns:
- JavaClass object for given runtime class
- Throws:
java.lang.ClassNotFoundException
- if the class is not in the Repository, and its representation could not be found- See Also:
Class

getClassPath
public ClassPath getClassPath()
ClassPath associated with the Repository.- Specified by:
getClassPath
in interfaceRepository
-
