All Superinterfaces:

MessageTransformer

All Known Subinterfaces:

DataDictionary<T>, ValidationProcessor, VariableExtractor

All Known Implementing Classes:

AbstractMessageProcessor

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public interface MessageProcessor
extends MessageTransformer

Processor performs operations on the given message. The processor is able to change message content such as payload and headers.

Method Details

lookup

static <T extends MessageProcessor,
B extends MessageProcessor.Builder<T,
B>>
Optional<MessageProcessor.Builder<T,B>> lookup(String processor)

Resolves processor from resource path lookup with given processor resource name. Scans classpath for processor meta information with given name and returns instance of processor. Returns optional instead of throwing exception when no processor could be found.

Parameters:

processor -

Returns:

process

void process(Message message,
 TestContext context)

Process message with given test context. Processors can change the message payload and headers.

Parameters:

message - the message to process.

context - the current test context.

transform

default Message transform(Message message,
 TestContext context)

Adapt to message transformer API.

Specified by:

transform in interface MessageTransformer

Parameters:

message - the message to process.

context - the current test context.

Returns:
