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.

getEndpointKey

public String getEndpointKey()

Specified by:

getEndpointKey in interface org.apache.camel.Endpoint

getCamelContext

public org.apache.camel.CamelContext getCamelContext()

Specified by:

getCamelContext in interface org.apache.camel.CamelContextAware

Specified by:

getCamelContext in interface org.apache.camel.Endpoint

public org.apache.camel.AsyncProducer createAsyncProducer()
                                                   throws Exception

Specified by:

createAsyncProducer in interface org.apache.camel.Endpoint

Throws:

Exception

getComponent

public org.apache.camel.Component getComponent()

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

setComponent

public void setComponent(org.apache.camel.Component component)

setCamelContext

public void setCamelContext(org.apache.camel.CamelContext camelContext)

Specified by:

setCamelContext in interface org.apache.camel.CamelContextAware

Specified by:

setCamelContext in interface org.apache.camel.Endpoint

createPollingConsumer

public org.apache.camel.PollingConsumer createPollingConsumer()
                                                       throws Exception

Specified by:

createPollingConsumer in interface org.apache.camel.Endpoint

Throws:

Exception

createExchange

public org.apache.camel.Exchange createExchange()

Specified by:

createExchange in interface org.apache.camel.Endpoint

createExchange

public org.apache.camel.Exchange createExchange(org.apache.camel.ExchangePattern pattern)

Specified by:

createExchange in interface org.apache.camel.Endpoint

configureExchange

public void configureExchange(org.apache.camel.Exchange exchange)

Specified by:

configureExchange in interface org.apache.camel.Endpoint

getExchangePattern

public org.apache.camel.ExchangePattern getExchangePattern()

Specified by:

getExchangePattern in interface org.apache.camel.Endpoint

setExchangePattern

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

Sets the default exchange pattern when creating an exchange.

isAutowiredEnabled

public boolean isAutowiredEnabled()

setAutowiredEnabled

public void setAutowiredEnabled(boolean autowiredEnabled)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

isLazyStartProducer

public boolean isLazyStartProducer()

setLazyStartProducer

public void setLazyStartProducer(boolean lazyStartProducer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the 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()

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()

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 it is full.

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

getPollingConsumerBlockTimeout

public long getPollingConsumerBlockTimeout()

setPollingConsumerBlockTimeout

public void setPollingConsumerBlockTimeout(long pollingConsumerBlockTimeout)

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

See Also:

setPollingConsumerBlockWhenFull(boolean)

isPollingConsumerCopy

public boolean isPollingConsumerCopy()

setPollingConsumerCopy

public void setPollingConsumerCopy(boolean pollingConsumerCopy)

Sets whether to copy the exchange when adding to the internal queue off when EventDrivenPollingConsumer is being used. Important: When copy is enabled then the unit of work is handed over from the current exchange to the copied exchange instance. And therefore its the responsible of the PollingConsumer to done the unit of work on the received exchanges. When the polled exchange is no longer needed then MUST call UnitOfWork.done(Exchange). Default is false to not copy.

configureProperties

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

Specified by:

configureProperties in interface org.apache.camel.Endpoint

setProperties

public void setProperties(Object bean,
                          Map<String,Object> parameters)

Sets the bean properties on the given bean.

This is the same logical implementation as DefaultComponent.setProperties(Object, java.util.Map)

Parameters:

bean - the bean

parameters - properties to set

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 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.

isSingleton

public boolean isSingleton()

An endpoint should favour to be singleton by default, only in some rare special cases can an endpoint be non-singleton. This implementation is singleton and this method returns true.

Specified by:

isSingleton in interface org.apache.camel.IsSingleton

isLenientProperties

public boolean isLenientProperties()

Specified by:

isLenientProperties in interface org.apache.camel.Endpoint
