Method Detail

toString

public String toString()

Overrides:

toString in class Object

description

protected String description()

getShortName

public String getShortName()

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

Specified by:

getLabel in interface org.apache.camel.NamedNode

Overrides:

getLabel in class ExpressionNode

setExpression

public void setExpression(ExpressionDefinition expression)

Expression used as the predicate to evaluate whether this when should trigger and route the message or not.

Overrides:

setExpression in class ExpressionNode

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
