javax.resource.spi.endpoint Interface MessageEndpoint

public interface MessageEndpoint

This defines a contract for a message endpoint. This is implemented by an application server.

版本:: 1.0
作者:: Ram Jeyaraman

方法摘要
`void`	`afterDelivery()` This is called by a resource adapter after a message is delivered.
`void`	`beforeDelivery(Method method)` This is called by a resource adapter before a message is delivered.
`void`	`release()` This method may be called by the resource adapter to indicate that it no longer needs a proxy endpoint instance.

方法详细信息

beforeDelivery

void beforeDelivery(Method method)
                    throws NoSuchMethodException,
                           ResourceException

This is called by a resource adapter before a message is delivered.

参数:: method - description of a target method. This information about the intended target method allows an application server to decide whether to start a transaction during this method call, depending on the transaction preferences of the target method. The processing (by the application server) of the actual message delivery method call on the endpoint must be independent of the class loader associated with this descriptive method object.
抛出异常:: NoSuchMethodException - indicates that the specified method does not exist on the target endpoint.; ResourceException - generic exception.; ApplicationServerInternalException - indicates an error condition in the application server.; IllegalStateException - indicates that the endpoint is in an illegal state for the method invocation. For example, this occurs when beforeDelivery and afterDelivery method calls are not paired.; UnavailableException - indicates that the endpoint is not available.

afterDelivery

void afterDelivery()
                   throws ResourceException

This is called by a resource adapter after a message is delivered.

抛出异常:: ResourceException - generic exception.; ApplicationServerInternalException - indicates an error condition in the application server.; IllegalStateException - indicates that the endpoint is in an illegal state for the method invocation. For example, this occurs when beforeDelivery and afterDelivery method calls are not paired.; UnavailableException - indicates that the endpoint is not available.

release

void release()

This method may be called by the resource adapter to indicate that it no longer needs a proxy endpoint instance. This hint may be used by the application server for endpoint pooling decisions.
