abstract class AbstractClassPathRepository extends java.lang.Object implements Repository
This abstract class provides a logic of a loadingJavaClass
objects class names viaClassPath
.Subclasses can choose caching strategy of the objects by implementing the abstract methods (e.g.,
storeClass(JavaClass)
andfindClass(String)
).- Since:

clear
public abstract void clear()
Description copied from interface:Repository
Clears all entries from cache.- Specified by:
clear
in interfaceRepository
-
findClass
public abstract JavaClass findClass(java.lang.String className)
Description copied from interface:Repository
Finds the class with the name provided, if the class isn't there, return NULL.- Specified by:
findClass
in interfaceRepository
-
getClassPath
public ClassPath getClassPath()
Description copied from interface:Repository
Gets the ClassPath associated with this Repository- Specified by:
getClassPath
in interfaceRepository
-
loadClass
public JavaClass loadClass(java.lang.Class<?> clazz) throws java.lang.ClassNotFoundException
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.- 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

loadClass
private JavaClass loadClass(java.io.InputStream inputStream, java.lang.String className) throws java.lang.ClassNotFoundException
- Throws:
java.lang.ClassNotFoundException
-
loadClass
public JavaClass loadClass(java.lang.String className) throws java.lang.ClassNotFoundException
Finds 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
-
removeClass
public abstract void removeClass(JavaClass javaClass)
Description copied from interface:Repository
Removes class from repository- Specified by:
removeClass
in interfaceRepository
-
storeClass
public abstract void storeClass(JavaClass javaClass)
Description copied from interface:Repository
Stores the provided class under "clazz.getClassName()"- Specified by:
storeClass
in interfaceRepository
