Class MemorySensitiveClassPathRepository

java.lang.Object
org.apache.bcel.util.MemorySensitiveClassPathRepository
All Implemented Interfaces:
Repository
Direct Known Subclasses:
SyntheticRepository
public class MemorySensitiveClassPathRepository extends Object
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(). This repository holds onto classes with SoftReferences, and will reload as needed, in cases where memory sizes are important.

    • storeClass

      public void storeClass(JavaClass clazz)
      Store a new JavaClass instance into this Repository.
      Specified by:
      storeClass in interface Repository

    • removeClass

      public void removeClass(JavaClass clazz)
      Remove class from repository
      Specified by:
      removeClass in interface Repository

    • findClass

      public JavaClass findClass(String className)
      Find an already defined (cached) JavaClass object by name.
      Specified by:
      findClass in interface Repository

    • clear

      public void clear()
      Clear all entries from cache.
      Specified by:
      clear in interface Repository

    • loadClass

      public JavaClass loadClass(String className) throws 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 interface Repository
      Parameters:
      className - the name of the class
      Returns:
      the JavaClass object
      Throws:
      ClassNotFoundException - if the class is not in the Repository, and could not be found on the classpath

    • loadClass

      public JavaClass loadClass(Class<?> clazz) throws 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 interface Repository
      Parameters:
      clazz - the runtime Class object
      Returns:
      JavaClass object for given runtime class
      Throws:
      ClassNotFoundException - if the class is not in the Repository, and its representation could not be found
