Interface Processor

All Known Implementing Classes:

AbstractProcessor, JspProcessor

public interface Processor

A Processor handles interaction of a Block. It is like a Renderer, but it renders nothing, it only can change the state of the block, and hence influence the renderers. The other difference is that there be several Blocks in a request, which are all rendered, but at most one of them has its Processor executed. Processing itself happens with the process(org.mmbase.util.functions.Parameters) method, which is typically done using Framework.process(org.mmbase.framework.Processor, org.mmbase.util.functions.Parameters, org.mmbase.util.functions.Parameters).

Method Summary

Block	getBlock() Every processor processes for a certain block.
Parameter[]	getParameters() A processor may need certain parameters.
URI	getUri() An URI which may identify the implementation of this Renderer.
void	process(Parameters blockParameters) Process.

Method Detail

getBlock

Block getBlock()

Every processor processes for a certain block.

getParameters

Parameter[] getParameters()

A processor may need certain parameters. These are added to the block-parameters. This method is called on instantation of the processor.

process

void process(Parameters blockParameters)
             throws FrameworkException

Process. In case of e.g. a JSPProcessor, the parameters must also contain the Http Servlet response and request, besided specific parameters for this component.

Throws:

FrameworkException

getUri

URI getUri()

An URI which may identify the implementation of this Renderer.
