process
abstract public boolean process() throws ResourceNotFoundException, ParseErrorException, Exception(Code)
Perform any subsequent processing that might need to be done by a resource. In the case of a template the actual parsing of the input stream needs to be performed. Whether the resource could be processed successfully.For a org.apache.velocity.Template or org.apache.velocity.runtime.resource.ContentResource, thisindicates whether the resource could be read.
