Class DefaultMessageCollection

java.lang.Object

org.mule.DefaultMuleMessage

org.mule.DefaultMessageCollection

All Implemented Interfaces:

Serializable, MuleMessage, MuleMessageCollection, ThreadSafeAccess, DeserializationPostInitialisable

public class DefaultMessageCollection
extends DefaultMuleMessage
implements MuleMessageCollection

A MuleMessage type that manages a collection of MuleMessage Objects. Typically this type of message is only used when users explicitly want to work with aggregated or re-sequenced collections of messages. Note that the DefaultMuleMessage.getPayload() for this message will return a List of payload objects for each of the Mule messages stored in this collection. Calling MuleMessage.getPayload(Class) will attempt to transform all payloads and return a List. The methods MuleMessage.getPayloadAsString() and MuleMessage.getPayloadAsBytes() are unsupported, instead users should call MuleMessage.getPayload(Class) and pass in the return type byte[].class or String.class.

setPayload

public void setPayload(Object payload)

Description copied from class: DefaultMuleMessage

Update the message payload. This is typically only called if the payload was originally an InputStream. In which case, if the InputStream is consumed, it needs to be replaced for future access.

Specified by:

setPayload in interface MuleMessage

Overrides:

setPayload in class DefaultMuleMessage

Parameters:

payload - the object to assign as the message payload

getPayload

public Object getPayload(Class outputType)
                  throws TransformerException

Applies the MuleMessage.getPayload(Class) call to every message in the collection and returns a List of results. Will attempt to obtain the payload of this message with the desired Class type. This will try and resolve a transformer that can do this transformation. If a transformer cannot be found an exception is thrown. Any transformers added to the registry will be checked for compatibility

Specified by:

getPayload in interface MuleMessage

Overrides:

getPayload in class DefaultMuleMessage

Parameters:

outputType - the desired return type

Returns:

The converted payload of this message. Note that this method will not alter the payload of this message *unless* the payload is an InputStream in which case the stream will be read and the payload will become the fully read stream.

Throws:

TransformerException - if a transformer cannot be found or there is an error during transformation of the payload

size

public int size()

Specified by:

size in interface MuleMessageCollection

getPayloadAsBytes

public byte[] getPayloadAsBytes()
                         throws Exception

Converts the message implementation into a byte array representation

Specified by:

getPayloadAsBytes in interface MuleMessage

Overrides:

getPayloadAsBytes in class DefaultMuleMessage

Returns:

byte array of the message

Throws:

Exception - Implemetation may throw an endpoint specific exception

getPayloadAsString

public String getPayloadAsString(String encoding)
                          throws Exception

Converts the message implementation into a String representation

Specified by:

getPayloadAsString in interface MuleMessage

Overrides:

getPayloadAsString in class DefaultMuleMessage

Parameters:

encoding - The encoding to use when transforming the message (if necessary). The parameter is used when converting from a byte array

Returns:

String representation of the message payload

Throws:

Exception - Implementation may throw an endpoint specific exception

getPayloadForLogging

public String getPayloadForLogging(String encoding)

Get the message payload for logging without throwing exception Converts the message implementation into a String representation. If encoding is required it will use the encoding set on the message

Specified by:

getPayloadForLogging in interface MuleMessage

Overrides:

getPayloadForLogging in class DefaultMuleMessage

Returns:

message payload as object

getPayloadForLogging

public String getPayloadForLogging()

Get the message payload for logging without throwing exception Converts the message implementation into a String representation.

Specified by:

getPayloadForLogging in interface MuleMessage

Overrides:

getPayloadForLogging in class DefaultMuleMessage

Returns:

message payload as object

newThreadCopy

public ThreadSafeAccess newThreadCopy()

We need to overload this if we find we want to make this class available to users, but the copy will be expensive;

Specified by:

newThreadCopy in interface ThreadSafeAccess

Overrides:

newThreadCopy in class DefaultMuleMessage

Returns:

A new instance of the implementing class, unbound to any thread and mutable.

createInboundMessage

public MuleMessage createInboundMessage()
