                        throws UnableToCompleteException

Description copied from interface: ResourceGenerator

Produce the right-hand-side of a Java assignment expression to provide the singleton instance object for a particular resource.

Example:

 new MySampleResource() { public Foo getFoo() { ... } }
 

Specified by:

createAssignment in interface ResourceGenerator

Specified by:

createAssignment in class AbstractResourceGenerator

A no-op implementation.

Specified by:

init in interface ResourceGenerator

Overrides:

init in class AbstractResourceGenerator

Throws:

UnableToCompleteException

prepare

public void prepare(TreeLogger logger,
                    ResourceContext context,
                    ClientBundleRequirements requirements,
                    JMethod method)
             throws UnableToCompleteException

Throws:

UnableToCompleteException

getBaseclassInterfaceName

protected String getBaseclassInterfaceName()

Return the name of the class which is at the base of the CssResource generation tree. Since obfuscation is done globally, this should be the base class for all resources in the compilation that should be included in the global obfuscation.

getResourceImplAsString

protected String getResourceImplAsString(TreeLogger logger,
                                         ResourceContext context,
