Class DefaultEndpoint

java.lang.Object
  org.apache.camel.impl.ServiceSupport
      org.apache.camel.impl.DefaultEndpoint

All Implemented Interfaces:

CamelContextAware, Endpoint, IsSingleton, Service, ShutdownableService, HasId

Direct Known Subclasses:

BrowseEndpoint, DirectEndpoint, LanguageEndpoint, MockEndpoint, ScheduledPollEndpoint, SedaEndpoint, TimerEndpoint

public abstract class DefaultEndpoint
extends ServiceSupport
implements Endpoint, HasId, CamelContextAware

A default endpoint useful for implementation inheritance.

Components which leverages asynchronous processing model should check the isSynchronous() to determine if asynchronous processing is allowed. The synchronous option on the endpoint allows Camel end users to dictate whether they want the asynchronous model or not. The option is default false which means asynchronous processing is allowed.

Constructor Detail

DefaultEndpoint

protected DefaultEndpoint(String endpointUri,
                          Component component)

Constructs a fully-initialized DefaultEndpoint instance. This is the preferred method of constructing an object from Java code (as opposed to Spring beans, etc.).

Parameters:

endpointUri - the full URI used to create this endpoint

component - the component that created this endpoint

DefaultEndpoint

protected DefaultEndpoint(String endpointUri,
                          CamelContext camelContext)

Constructs a DefaultEndpoint instance which has not been created using a Component.

Note: It is preferred to create endpoints using the associated component.

Parameters:

endpointUri - the full URI used to create this endpoint

camelContext - the Camel Context in which this endpoint is operating

DefaultEndpoint

protected DefaultEndpoint(String endpointUri)

Constructs a partially-initialized DefaultEndpoint instance.

Note: It is preferred to create endpoints using the associated component.

Parameters:

endpointUri - the full URI used to create this endpoint

DefaultEndpoint

protected DefaultEndpoint()

Constructs a partially-initialized DefaultEndpoint instance. Useful when creating endpoints manually (e.g., as beans in Spring).

Please note that the endpoint URI must be set through properties (or overriding createEndpointUri() if one uses this constructor.

Note: It is preferred to create endpoints using the associated component.

Method Detail

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object object)

Overrides:

equals in class Object

toString

public String toString()

Overrides:

toString in class Object

getId

public String getId()

Returns a unique String ID which can be used for aliasing without having to use the whole URI which is not unique

Specified by:

getId in interface HasId

Returns:

the id

getEndpointUri

public String getEndpointUri()

Description copied from interface: Endpoint

Returns the string representation of the endpoint URI

Specified by:

getEndpointUri in interface Endpoint

Returns:

the endpoint URI

getEndpointKey

public String getEndpointKey()

Description copied from interface: Endpoint

Returns a string key of this endpoint.

This key is used by LifecycleStrategy when registering endpoint. This allows to register different instances of endpoints with the same key.

For JMX mbeans this allows us to use the same JMX Mbean for all endpoints that are logical the same but have different parameters. For instance the http endpoint.

Specified by:

getEndpointKey in interface Endpoint

Returns:

the endpoint key

getCamelContext

public CamelContext getCamelContext()

Description copied from interface: Endpoint

Returns the context which created the endpoint

Specified by:

getCamelContext in interface CamelContextAware

Specified by:

getCamelContext in interface Endpoint

Returns:

the context which created the endpoint

getComponent

public Component getComponent()

Returns the component that created this endpoint.

Returns:

the component that created this endpoint, or null if none set

setCamelContext

public void setCamelContext(CamelContext camelContext)

Description copied from interface: Endpoint

Sets the camel context.

Specified by:

setCamelContext in interface CamelContextAware

Specified by:

setCamelContext in interface Endpoint

Parameters:

camelContext - the camel context

createPollingConsumer

public PollingConsumer createPollingConsumer()
                                      throws Exception

Description copied from interface: Endpoint

Creates a new Polling Consumer so that the caller can poll message exchanges from the consumer using PollingConsumer.receive(), PollingConsumer.receiveNoWait() or PollingConsumer.receive(long) whenever it is ready to do so rather than using the Event Based Consumer returned by Endpoint.createConsumer(Processor)

Specified by:

createPollingConsumer in interface Endpoint

Returns:

a newly created pull consumer

Throws:

Exception - if the pull consumer could not be created

createExchange

public Exchange createExchange(Exchange exchange)

Description copied from interface: Endpoint

Creates a new exchange for communicating with this exchange using the given exchange to pre-populate the values of the headers and messages

Specified by:

createExchange in interface Endpoint

Parameters:

exchange - given exchange to use for pre-populate

Returns:

a new exchange

getExchangeType

public Class<Exchange> getExchangeType()

Returns the type of the exchange which is generated by this component

createExchange

public Exchange createExchange()

Description copied from interface: Endpoint

Create a new exchange for communicating with this endpoint

Specified by:

createExchange in interface Endpoint

Returns:

a new exchange

createExchange

public Exchange createExchange(ExchangePattern pattern)

Description copied from interface: Endpoint

Create a new exchange for communicating with this endpoint with the specified ExchangePattern such as whether its going to be an ExchangePattern.InOnly or ExchangePattern.InOut exchange

Specified by:

createExchange in interface Endpoint

Parameters:

pattern - the message exchange pattern for the exchange

Returns:

a new exchange

getExchangePattern

public ExchangePattern getExchangePattern()

Returns the default exchange pattern to use for createExchange().

See Also:

setExchangePattern(ExchangePattern exchangePattern)

setExchangePattern

public void setExchangePattern(ExchangePattern exchangePattern)

Sets the default exchange pattern to use for createExchange(). The default value is ExchangePattern.InOnly

isSynchronous

public boolean isSynchronous()

Returns whether synchronous processing should be strictly used.

See Also:

setSynchronous(boolean synchronous)

setSynchronous

public void setSynchronous(boolean synchronous)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

Parameters:

synchronous - true to enforce synchronous processing

configureProperties

public void configureProperties(Map<String,Object> options)

Description copied from interface: Endpoint

Configure properties on this endpoint.

Specified by:

configureProperties in interface Endpoint

Parameters:

options - the options (properties)

createEndpointUri

protected String createEndpointUri()

A factory method to lazily create the endpointUri if none is specified

setEndpointUriIfNotSpecified

public void setEndpointUriIfNotSpecified(String value)

Sets the endpointUri if it has not been specified yet via some kind of dependency injection mechanism. This allows dependency injection frameworks such as Spring or Guice to set the default endpoint URI in cases where it has not been explicitly configured using the name/context in which an Endpoint is created.

setEndpointUri

protected void setEndpointUri(String endpointUri)

Sets the URI that created this endpoint.

isLenientProperties

public boolean isLenientProperties()

Description copied from interface: Endpoint

Should all properties be known or does the endpoint allow unknown options?

lenient = false means that the endpoint should validate that all given options is known and configured properly. lenient = true means that the endpoint allows additional unknown options to be passed to it but does not throw a ResolveEndpointFailedException when creating the endpoint.

This options is used by a few components for instance the HTTP based that can have dynamic URI options appended that is targeted for an external system.

Most endpoints is configured to be not lenient.

Specified by:

isLenientProperties in interface Endpoint

Returns:

whether properties is lenient or not

doStart

protected void doStart()
                throws Exception

Specified by:

doStart in class ServiceSupport

Throws:

Exception

doStop

protected void doStop()
               throws Exception

Specified by:

doStop in class ServiceSupport

Throws:

Exception
