Method Summary

java.lang.String	getBundleIdFromURL(java.net.URL url) Deprecated. use getFile() or getClassLoaderName()
java.lang.ClassLoader	getClassLoader()
java.lang.String	getClassLoaderName() In an environment with multiple class loaders allows each to be identified using something safer and possibly shorter than toString
java.util.List	getDefinitions(java.lang.ClassLoader loader, WeavingAdaptor adaptor) Allow custom parsing of aop.xml or alternative mechanism for providing Definitions
java.lang.String	getFile(java.net.URL url) Format a URL
java.lang.String	getId() In an environment with multiple class loaders allows messages to identified according to the weaving context
java.util.Enumeration	getResources(java.lang.String name) Allows the standard ClassLoader.getResources() mechanisms to be replaced with a different implementation.
boolean	isLocallyDefined(java.lang.String classname) Return true if the classloader associated with this weaving context is the one that will define the class with the specified name.

Method Detail

getResources

java.util.Enumeration getResources(java.lang.String name)
                                   throws java.io.IOException

Allows the standard ClassLoader.getResources() mechanisms to be replaced with a different implementation. In an OSGi environment, this will allow for filtering to take place on the results of ClassLoader.getResources(). In a non-OSGi environment, ClassLoader.getResources should be returned.

Parameters:

name - the name of the resource to search for

Returns:

an enumeration containing all of the matching resources found

Throws:

java.io.IOException

getBundleIdFromURL

java.lang.String getBundleIdFromURL(java.net.URL url)

Deprecated. use getFile() or getClassLoaderName()

In an OSGi environment, determin which bundle a URL originated from. In a non-OSGi environment, implementors should return null.

Parameters:

url -

Returns:

getClassLoaderName

java.lang.String getClassLoaderName()

In an environment with multiple class loaders allows each to be identified using something safer and possibly shorter than toString

Returns:

name of the associated class loader

getClassLoader

java.lang.ClassLoader getClassLoader()

getFile

java.lang.String getFile(java.net.URL url)

Format a URL

Returns:

filename

getId

java.lang.String getId()

In an environment with multiple class loaders allows messages to identified according to the weaving context

Returns:

short name

isLocallyDefined

boolean isLocallyDefined(java.lang.String classname)

Return true if the classloader associated with this weaving context is the one that will define the class with the specified name. In a delegating classloader hierarchy this might check the parent won't define it and the child will - in OSGi it will do something else.

Parameters:

classname - name of the class, eg. "java.lang.String"

Returns:

true if the associated classloader will define the class

getDefinitions

java.util.List getDefinitions(java.lang.ClassLoader loader,
                              WeavingAdaptor adaptor)

Allow custom parsing of aop.xml or alternative mechanism for providing Definitions

Parameters:

loader -

adaptor -

Returns:

List containing 0 or more Definition instances
