Method Detail

transform

protected abstract ResourceTransformer.Resource[] transform(ResourceTransformer.Resource r)

The implementation of this method potentially transforms the supplied resource. The resource can be a regular class file or configuration text file or some other kind of files. If the implementing method detects no transformation is needed it must return empty array. Otherwise it must create a new resource (or new resources) containing transformed resource (potentially additional created resources). If return value contains more than one resource then resource at array index zero is always considered to be replacement of original resource and other resources (since array index of 1 including) represent additional resources created dynamically that must be added to target environment (e.g. jar archive or defining class loader).

Parameters:

r - the resource to be transformed. The buffer returned by ResourceTransformer.Resource.getData() method must not be modified.

Returns:

either empty array if no transformation is performed or a new resource (or multiple resources) representing transformed resource (or potentially additional created resources)
