# Class SyntheticRepository

java.lang.Object
org.apache.bcel.util.MemorySensitiveClassPathRepository
org.apache.bcel.util.SyntheticRepository

All Implemented Interfaces:
  `Repository`

public class SyntheticRepository extends MemorySensitiveClassPathRepository
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 uses a factory design, allowing it to maintain a collection of different classpaths, and as such It is designed to be used as a singleton per classpath.

- ## Method Details

  - ### getInstance

    public static SyntheticRepository getInstance()

  - ### getInstance

    public static SyntheticRepository getInstance(ClassPath classPath)

  - ### 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
    See Also:
      - `Class`

  - ### 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
