public abstract class AbstractTemplateHandler
extends Object
implements ITemplateHandler

Basic abstract implementation of ITemplateHandler that takes care of the whole contract of this interface and offers a good base for the easy implementation of custom template handlers.

All handleX() implementations in this class are set to simply delegate to the next handler in the chain, so that subclasses can override only the handling methods that are really relevant to them.

3.0.0

Constructor Detail

AbstractTemplateHandler

protected AbstractTemplateHandler(ITemplateHandler next)

Create a new instance of this handler, specifying the handler that will be used as next step in the chain.

Parameters:

next - the next step in the chain.

AbstractTemplateHandler

protected AbstractTemplateHandler()

Create a new instance of this handler, not specifying the 'next' handler.

Method Detail

setNext

public void setNext(ITemplateHandler next)

Set the next handler in the chain, so that events can be (optionally) delegated to it.

This method is called when the chain of template handlers is conformed, always before starting the parsing and processing of a template.

Specified by:

setNext in interface ITemplateHandler

Parameters:

next - the next handler in the chain.

setContext

public void setContext(ITemplateContext context)

Set the processing context to be used, including template name, context, and also the engine configuration.

This method is called always before starting the parsing and processing of a template.

Specified by:

setContext in interface ITemplateHandler

Parameters:

context - the processing context.

getNext

protected final ITemplateHandler getNext()

Return the next handler in the chain, so that events can be delegated to it.

Returns:

the next handler in the chain.

getContext

protected final ITemplateContext getContext()

Return the processing context corresponding to the template execution for which the template handler instance has been created.

Returns:

the processing context
