Constructor Details

DefaultWeavingContext

public DefaultWeavingContext(ClassLoader loader)

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

Parameters:

loader -

Method Details

getResources

public Enumeration<URL> getResources(String name)
                              throws 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:

IOException

getBundleIdFromURL

public String getBundleIdFromURL(URL url)

Description copied from interface: IWeavingContext

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

Specified by:

getBundleIdFromURL in interface IWeavingContext

Parameters:

url -

Returns:

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

getClassLoaderName

public 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 ClassLoader getClassLoader()

Specified by:

getClassLoader in interface IWeavingContext

getFile

public String getFile(URL url)

Description copied from interface: IWeavingContext

Format a URL

Specified by:

getFile in interface IWeavingContext

Returns:

filename

getId

public 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 String getSuffix()

isLocallyDefined

public boolean isLocallyDefined(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 List<Definition> getDefinitions(ClassLoader loader,
 WeavingAdaptor adaptor)

Simply call weaving adaptor back to parse aop.xml

Specified by:

getDefinitions in interface IWeavingContext

Parameters:

loader -

adaptor -

Returns:

List containing 0 or more Definition instances
