Constructor Detail

WhenDefinition

public WhenDefinition()

WhenDefinition

public WhenDefinition(Predicate predicate)

WhenDefinition

public WhenDefinition(ExpressionDefinition expression)
Method Detail

toString

public String toString()
Overrides:
toString in class Object

getShortName

public String getShortName()
Description copied from class: OptionalIdentifiedDefinition
Returns a short name for this node which can be useful for ID generation or referring to related resources like images

Overrides:
getShortName in class ExpressionNode
Returns:
defaults to "node" but derived nodes should overload this to provide a unique name

createProcessor

public FilterProcessor createProcessor(RouteContext routeContext)
                                throws Exception
Description copied from class: ProcessorDefinition
Override this in definition class and implement logic to create the processor based on the definition model.

Overrides:
createProcessor in class ProcessorDefinition<ExpressionNode>
Throws:
Exception

endParent

public ProcessorDefinition endParent()
Description copied from class: ProcessorDefinition
Strategy to allow ProcessorDefinitions to have special logic when using end() in the DSL to return back to the intended parent.

For example a content based router we return back to the ChoiceDefinition when we end() from a WhenDefinition.

Overrides:
endParent in class ProcessorDefinition<ExpressionNode>
Returns:
the end
