Method Detail

getChannelName

@Nonnull
public java.lang.String getChannelName()

Description copied from interface: MessageEndpoint

Returns the name of the channel.

The channel name corresponds to the name of the underlying stream, queue or message log.

Specified by:

getChannelName in interface MessageEndpoint

Returns:

name of the channel

getMessageFormat

@Nonnull
public MessageFormat getMessageFormat()

getInterceptorChain

@Nonnull
public InterceptorChain getInterceptorChain()

Description copied from interface: MessageEndpoint

Returns the InterceptorChain of the MessageEndpoint.

Specified by:

getInterceptorChain in interface MessageEndpoint

Returns:

InterceptorChain

getEndpointType

@Nonnull
public EndpointType getEndpointType()

Description copied from interface: MessageEndpoint

Returns the type of the MessageEndpoint, either EndpointType.SENDER or EndpointType.RECEIVER.

Specified by:

getEndpointType in interface MessageEndpoint

Returns:

EndpointType

intercept

@Nullable
public TextMessage intercept(@Nonnull
                                       TextMessage message)

Description copied from interface: MessageEndpoint

Intercepts a message using all registered interceptors and returns the resulting message.

The interceptors are called in order. The result of one interceptor is propagated to the next interceptor in the chain, until the end of the chain is reached, or one interceptor has returned null.

If null is returned, the message must be dropped by the AbstractMessageEndpoint.

Every interceptor may transform the message, or may take additional actions like, for example, logging, monitoring or other things.

Specified by:

intercept in interface MessageEndpoint

Parameters:

message - the message to intercept

Returns:

the (possibly modified) message, or null if the message should be dropped.
