extends java.lang.Object
implements IWeavingContext

Use in non-OSGi environment

Field Summary

protected BcelWeakClassLoaderReference

loaderRef

Constructor Summary

DefaultWeavingContext(java.lang.ClassLoader loader)
Construct a new WeavingContext to use the specified ClassLoader This is the constructor which should be used.

Method Summary

java.lang.String	getBundleIdFromURL(java.net.URL url) In an OSGi environment, determin which bundle a URL originated from.
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<Definition>	getDefinitions(java.lang.ClassLoader loader, WeavingAdaptor adaptor) Simply call weaving adaptor back to parse aop.xml
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) Same as ClassLoader.getResources()
java.lang.String	getSuffix()
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.

Constructor Detail

DefaultWeavingContext

public DefaultWeavingContext(java.lang.ClassLoader loader)

Construct a new WeavingContext to use the specified ClassLoader This is the constructor which should be used.

Parameters:

loader -

Method Detail

getResources

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

Same as ClassLoader.getResources()

Specified by:

getResources in interface IWeavingContext

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

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

Description copied from interface: IWeavingContext

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

Specified by:

getBundleIdFromURL in interface IWeavingContext

Returns:

null as we are not in an OSGi environment (therefore no bundles)

getClassLoaderName

public java.lang.String getClassLoaderName()

Description copied from interface: IWeavingContext

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

Specified by:

getClassLoaderName in interface IWeavingContext

Returns:

classname@hashcode

getClassLoader

public java.lang.ClassLoader getClassLoader()

Specified by:

getClassLoader in interface IWeavingContext

getFile

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

Description copied from interface: IWeavingContext

Format a URL

Specified by:

getFile in interface IWeavingContext

Returns:

filename

getId

public java.lang.String getId()

Description copied from interface: IWeavingContext

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

Specified by:

getId in interface IWeavingContext

Returns:

unqualifiedclassname@hashcode

getSuffix

public java.lang.String getSuffix()

isLocallyDefined

public boolean isLocallyDefined(java.lang.String classname)

Description copied from interface: IWeavingContext

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.

Specified by:

isLocallyDefined in interface IWeavingContext

Parameters:

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

Returns:

true if the associated classloader will define the class

getDefinitions

public java.util.List<Definition> getDefinitions(java.lang.ClassLoader loader,
                                                 WeavingAdaptor adaptor)

Simply call weaving adaptor back to parse aop.xml

Specified by:

getDefinitions in interface IWeavingContext

Parameters:

weaver -

loader -

Returns:

List containing 0 or more Definition instances
