Class MemorySensitiveClassPathRepository

  • All Implemented Interfaces:
    Repository
    Direct Known Subclasses:
    SyntheticRepository
    public class MemorySensitiveClassPathRepository
extends java.lang.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.

      • clear

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

      • findClass

        public JavaClass findClass​(java.lang.String className)
        Find an already defined (cached) JavaClass object by name.
        Specified by:
        findClass in interface Repository
        Parameters:
        className - The class name.
        Returns:
        The JavaClass instance, or null.

      • storeClass

        public void storeClass​(JavaClass clazz)
        Store a new JavaClass instance into this Repository.
        Specified by:
        storeClass in interface Repository
        Parameters:
        clazz - The class to store.

      • getClassPath

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

      • 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 interface Repository
        Parameters:
        clazz - The runtime Class object.
        Returns:
        JavaClass object for given runtime class.
        Throws:
        java.lang.ClassNotFoundException - Thrown if the class is not in the Repository, and its representation could not be found

      • 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 interface Repository
        Parameters:
        className - The name of the class.
        Returns:
        The JavaClass object.
        Throws:
        java.lang.ClassNotFoundException - Thrown if the class is not in the Repository, and could not be found on the classpath
