All Implemented Interfaces:

org.apache.camel.CamelContextAware, org.apache.camel.Endpoint, org.apache.camel.IsSingleton, org.apache.camel.Service, org.apache.camel.ShutdownableService, org.apache.camel.spi.HasId, org.apache.camel.StatefulService, org.apache.camel.SuspendableService

Direct Known Subclasses:

AbstractApiEndpoint, ScheduledPollEndpoint

public abstract class DefaultEndpoint
extends org.apache.camel.support.service.ServiceSupport
implements org.apache.camel.Endpoint, org.apache.camel.spi.HasId, org.apache.camel.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,
                          org.apache.camel.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()

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.

Specified by:

createExchange in interface org.apache.camel.Endpoint

public org.apache.camel.ExchangePattern getExchangePattern()

Returns the default exchange pattern to use when creating an exchange.

setExchangePattern

public void setExchangePattern(org.apache.camel.ExchangePattern exchangePattern)

Sets the default exchange pattern when creating an exchange.

isSynchronous

public boolean isSynchronous()

Returns whether synchronous processing should be strictly used.

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

isBridgeErrorHandler

public boolean isBridgeErrorHandler()

setBridgeErrorHandler

public void setBridgeErrorHandler(boolean bridgeErrorHandler)

Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions occurred while the consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler.

By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN/ERROR level and ignored.

getExceptionHandler

public org.apache.camel.spi.ExceptionHandler getExceptionHandler()

setExceptionHandler

public void setExceptionHandler(org.apache.camel.spi.ExceptionHandler exceptionHandler)

To let the consumer use a custom ExceptionHandler. + Notice if the option bridgeErrorHandler is enabled then this options is not in use. + By default the consumer will deal with exceptions, that will be logged at WARN/ERROR level and ignored.

getPollingConsumerQueueSize

public int getPollingConsumerQueueSize()

Gets the PollingConsumer queue size, when EventDrivenPollingConsumer is being used. Notice some Camel components may have their own implementation of PollingConsumer and therefore not using the default EventDrivenPollingConsumer implementation.

The default value is 1000

setPollingConsumerQueueSize

public void setPollingConsumerQueueSize(int pollingConsumerQueueSize)

Sets the PollingConsumer queue size, when EventDrivenPollingConsumer is being used. Notice some Camel components may have their own implementation of PollingConsumer and therefore not using the default EventDrivenPollingConsumer implementation.

The default value is 1000

isPollingConsumerBlockWhenFull

public boolean isPollingConsumerBlockWhenFull()

Whether to block when adding to the internal queue off when EventDrivenPollingConsumer is being used. Notice some Camel components may have their own implementation of PollingConsumer and therefore not using the default EventDrivenPollingConsumer implementation.

Setting this option to false, will result in an IllegalStateException being thrown when trying to add to the queue, and its full.

The default value is true which will block the producer queue until the queue has space.

setPollingConsumerBlockWhenFull

public void setPollingConsumerBlockWhenFull(boolean pollingConsumerBlockWhenFull)

Set whether to block when adding to the internal queue off when EventDrivenPollingConsumer is being used. Notice some Camel components may have their own implementation of PollingConsumer and therefore not using the default EventDrivenPollingConsumer implementation.

Setting this option to false, will result in an IllegalStateException being thrown when trying to add to the queue, and its full.

The default value is true which will block the producer queue until the queue has space.

getPollingConsumerBlockTimeout

public long getPollingConsumerBlockTimeout()

Sets the timeout in millis to use when adding to the internal queue off when EventDrivenPollingConsumer is being used.

See Also:

setPollingConsumerBlockWhenFull(boolean)

setPollingConsumerBlockTimeout

public void setPollingConsumerBlockTimeout(long pollingConsumerBlockTimeout)

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.

setEndpointUri

protected void setEndpointUri(String endpointUri)

Sets the URI that created this endpoint.
