brooklyn.util.javalang
[Java] Class AggregateClassLoader

java.lang.Object
  java.lang.ClassLoader
      brooklyn.util.javalang.AggregateClassLoader

public class AggregateClassLoader
extends java.lang.ClassLoader

looks for classes and resources in the classloaders added here

similar to XStream's CompositeClassLoader, but also supporting resources, exposing more info, a few conveniences, and a nice toString

Method Summary
void add(int index, java.lang.ClassLoader classLoader)

Add a loader to the specific position in the search path.

void addFirst(java.lang.ClassLoader classLoader)

Add a loader to the first position in the search path.
void addLast(java.lang.ClassLoader classLoader)

Add a loader to the last position in the search path.
protected java.lang.Class findClass(java.lang.String name)

java.util.List getList()

Returns the _live_ (and modifiable) list of classloaders @return
java.net.URL getResource(java.lang.String name)

static AggregateClassLoader newInstanceWithDefaultLoaders()

creates default instance, with classloaders of Object and AggregateClassLoader
static AggregateClassLoader newInstanceWithNoLoaders()

creates default instance, with no classloaders (assuming this instance will itself be nested, or defaults will be added by caller)
java.lang.String toString()

Method Detail

add

public void add(int index, java.lang.ClassLoader classLoader)
Add a loader to the specific position in the search path. (It is callers responsibility to ensure that position is valid.)

public void addFirst(java.lang.ClassLoader classLoader)
Add a loader to the first position in the search path.

addLast

public void addLast(java.lang.ClassLoader classLoader)
Add a loader to the last position in the search path.

findClass

@Override
protected java.lang.Class findClass(java.lang.String name)

getList

public java.util.List getList()
Returns the _live_ (and modifiable) list of classloaders @return

getResource

@Override
public java.net.URL getResource(java.lang.String name)

newInstanceWithDefaultLoaders

public static AggregateClassLoader newInstanceWithDefaultLoaders()
creates default instance, with classloaders of Object and AggregateClassLoader

newInstanceWithNoLoaders

public static AggregateClassLoader newInstanceWithNoLoaders()
creates default instance, with no classloaders (assuming this instance will itself be nested, or defaults will be added by caller)

toString
