Class AbstractClassPathRepository

java.lang.Object
org.apache.bcel.util.AbstractClassPathRepository
All Implemented Interfaces:
Repository
Direct Known Subclasses:
ClassPathRepository, LruCacheClassPathRepository, MemorySensitiveClassPathRepository

abstract class AbstractClassPathRepository extends Object implements Repository
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)).

    • clear

      public abstract void clear()
      Description copied from interface: Repository
      Clears all entries from cache.
      Specified by:
      clear in interface Repository
    • findClass

      public abstract JavaClass findClass(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 interface Repository
    • getClassPath

      public ClassPath getClassPath()
      Description copied from interface: Repository
      Gets the ClassPath associated with this Repository
      Specified by:
      getClassPath in interface Repository
    • 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

    • loadClass

      private JavaClass loadClass(InputStream inputStream, String className) throws ClassNotFoundException
      Throws:
      ClassNotFoundException
    • 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

    • storeClass

      public abstract void storeClass(JavaClass javaClass)
      Description copied from interface: Repository
      Stores the provided class under "clazz.getClassName()"
