public interface IElementTagProcessor
extends IElementProcessor

Interface to be implemented by all element tag processors.

This kind of processors, the most common in most scenarios, are executed on the single open element or standalone element tag that matches their matching configuration (see IElementProcessor.

Using the structureHandler

For any actions involving modifications to the tag being processed or the markup structure, processors will use the IElementTagStructureHandler objects passed as argument to the process(ITemplateContext, IProcessableElementTag, IElementTagStructureHandler) method.

See the documentation for IElementTagStructureHandler for more info.

Abstract implementations

Two basic abstract implementations of this interface are offered:

• AbstractElementTagProcessor, meant for processors that match element events by their element name (i.e. without looking at any attributes).
• AbstractAttributeTagProcessor, meant for processors that match element events by one of their attributes (and optionally also the element name).

Method Detail

process

void process(ITemplateContext context,
             IProcessableElementTag tag,
             IElementTagStructureHandler structureHandler)

Execute the processor.

The IProcessableElementTag object argument is immutable, so all modifications to this object or any instructions to be given to the engine should be done through the specified IElementTagStructureHandler handler.

Parameters:

context - the execution context.

tag - the event this processor is executing on.

structureHandler - the handler that will centralise modifications and commands to the engine.
