Method Detail

toString

public String toString()

Overrides:

toString in class Object

description

protected String description()

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

Specified by:

getShortName in interface NamedNode

Overrides:

getShortName in class ExpressionNode

Returns:

defaults to "node" but derived nodes should overload this to provide a unique name

getLabel

public String getLabel()

Description copied from class: ProcessorDefinition

Returns a label to describe this node such as the expression if some kind of expression node

Overrides:

getLabel in class ExpressionNode

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
