Method Details

id

public S id(@Nullable
 String id)

Description copied from class: IntegrationComponentSpec

Configure the component identifier. Used as the beanName to register the bean in the application context for this component.

Overrides:

id in class IntegrationComponentSpec<S extends EndpointSpec<S,F,H>,reactor.util.function.Tuple2<F extends BeanNameAware & FactoryBean<? extends AbstractEndpoint>,H>>

Parameters:

id - the id.

Returns:

the spec.

public S poller(Function<PollerFactory,PollerSpec> pollers)

Parameters:

pollers - the pollers

Returns:

the endpoint spec.

poller

public S poller(PollerSpec pollerMetadataSpec)

Parameters:

pollerMetadataSpec - the pollerMetadataSpec

Returns:

poller

public abstract S poller(PollerMetadata pollerMetadata)

Parameters:

pollerMetadata - the pollerMetadata

Returns:

phase

public abstract S phase(int phase)

Parameters:

phase - the phase.

Returns:

the endpoint spec.

getComponentsToRegister

public Map<Object,String> getComponentsToRegister()

Specified by:

getComponentsToRegister in interface ComponentsRegistration

doGet

protected reactor.util.function.Tuple2<F,H> doGet()

Overrides:

doGet in class IntegrationComponentSpec<S extends EndpointSpec<S,F,H>,reactor.util.function.Tuple2<F extends BeanNameAware & FactoryBean<? extends AbstractEndpoint>,H>>

assertHandler

protected void assertHandler()

obtainInputChannelFromFlow

protected MessageChannel obtainInputChannelFromFlow(IntegrationFlow subFlow)

Try to get a MessageChannel as an input for the provided IntegrationFlow or create one and wrap the provided flow to a new one.

Parameters:

subFlow - the IntegrationFlow to extract input channel.

Returns:

the input channel of the flow of create one

Since:

5.0.4

obtainInputChannelFromFlow

protected MessageChannel obtainInputChannelFromFlow(IntegrationFlow subFlow,
 boolean evaluateInternalBuilder)

Try to get a MessageChannel as an input for the provided IntegrationFlow or create one and wrap the provided flow to a new one.

Parameters:

subFlow - the IntegrationFlow to extract input channel.

evaluateInternalBuilder - true if an internal IntegrationFlowDefinition should be evaluated to an IntegrationFlow component or left as a builder in the componentsToRegister for future use-case. For example the builder is used for router configurations to retain beans registration order for parent-child dependencies.

Returns:

the input channel of the flow of create one

Since:

5.0.4
