Method Detail

decode

public void decode()
            throws MessageDecodingException

Decode message data from the source and store it so that it may be retrieved via MessageDecoder.getMessageContext().

Specified by:

decode in interface MessageDecoder<MessageType extends XMLObject>

Overrides:

decode in class AbstractHttpServletRequestMessageDecoder<MessageType extends XMLObject>

Throws:

MessageDecodingException - if there is a problem decoding the message context

getParserPool

@Nonnull
public ParserPool getParserPool()

Gets the parser pool used to deserialize incoming messages.

Returns:

parser pool used to deserialize incoming messages

setParserPool

public void setParserPool(@Nonnull
                 ParserPool pool)

Sets the parser pool used to deserialize incoming messages.

Parameters:

pool - parser pool used to deserialize incoming messages

doDestroy

protected void doDestroy()

Overrides:

doDestroy in class AbstractHttpServletRequestMessageDecoder<MessageType extends XMLObject>

doInitialize

protected void doInitialize()
                     throws ComponentInitializationException

Overrides:

doInitialize in class AbstractHttpServletRequestMessageDecoder<MessageType extends XMLObject>

Throws:

ComponentInitializationException

logDecodedMessage

protected void logDecodedMessage()

Log the decoded message to the protocol message logger.

getMessageToLog

protected XMLObject getMessageToLog()

Get the XMLObject which will be logged as the protocol message.

Returns:

the XMLObject message considered to be the protocol message for logging purposes

unmarshallMessage

protected XMLObject unmarshallMessage(InputStream messageStream)
                               throws MessageDecodingException

Helper method that deserializes and unmarshalls the message from the given stream.

Parameters:

messageStream - input stream containing the message

Returns:

the inbound message

Throws:

MessageDecodingException - thrown if there is a problem deserializing and unmarshalling the message

validateHttpRequest

protected void validateHttpRequest(javax.servlet.http.HttpServletRequest request)
                            throws MessageDecodingException

Perform optional validation of the inbound HttpServletRequest.

This method is called before the main MessageDecoder.decode() logic}.

The default behavior is a no-op. Subclasses may override with specific constraints.

Parameters:

request - the HTTP request being validate

Throws:

MessageDecodingException - if request is not considered valid
