PolicyDefinition

public PolicyDefinition()

PolicyDefinition

public PolicyDefinition(Policy policy)

Method Detail

toString

public String toString()

Overrides:

toString in class OutputDefinition<PolicyDefinition>

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 OutputDefinition<PolicyDefinition>

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 ProcessorDefinition<PolicyDefinition>

isAbstract

public boolean isAbstract()

Description copied from class: ProcessorDefinition

Whether this model is abstract or not.

An abstract model is something that is used for configuring cross cutting concerns such as error handling, transaction policies, interceptors etc.

Regular definitions is what is part of the route, such as ToDefinition, WireTapDefinition and the likes.

Will by default return false to indicate regular definition, so all the abstract definitions must override this method and return true instead.

This information is used in camel-spring to let Camel work a bit on the model provided by JAXB from the Spring XML file. This is needed to handle those cross cutting concerns properly. The Java DSL does not have this issue as it can work this out directly using the fluent builder methods.

Overrides:

isAbstract in class ProcessorDefinition<PolicyDefinition>

Returns:

true for abstract, otherwise false for regular.

getRef

public String getRef()

setRef

public void setRef(String ref)

setType

public void setType(Class<? extends Policy> type)

Sets a policy type that this definition should scope within.

Is used for convention over configuration situations where the policy should be automatic looked up in the registry and it should be based on this type. For instance a TransactedPolicy can be set as type for easy transaction configuration.

Will by default scope to the wide Policy

Parameters:

type - the policy type

ref

public PolicyDefinition ref(String ref)

Sets a reference to use for lookup the policy in the registry.

Parameters:

ref - the reference

Returns:

the builder

createProcessor

public Processor 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<PolicyDefinition>

Throws:

Exception

resolvePolicy

protected Policy resolvePolicy(RouteContext routeContext)
