Class ReplayDispatcher

java.lang.Object

org.apache.synapse.transport.http.conn.ReplayDispatcher

public class ReplayDispatcher
extends Object

Singleton manager class responsible for buffering replay data and asynchronously writing it to a configured ReplayDataWriter. A dedicated background thread consumes records from the queue and writes them using the ReplayDataWriter implementation configured dynamically through properties. This class is thread-safe and supports graceful shutdown by closing the writer and stopping the background thread.

Method Summary

Modifier and Type	Method	Description
void	addReplayRecord(String messageId, Map<String,Object> metadata, byte[] data)	Adds a replay record to the internal buffer queue for later asynchronous writing.
void	addReplayRecord(ByteBuffer dataBuffer, int byteWritten, String messageId, Map<String,Object> metadata)	Convenience method to wrap data in ByteBuffer and delegate to addReplayRecord(String, byte[], Map).
static ReplayDispatcher	getInstance()	Returns the singleton instance of the ReplayDispatcher, creating it if necessary.

Method Details

getInstance

public static ReplayDispatcher getInstance()

Returns the singleton instance of the ReplayDispatcher, creating it if necessary. Dynamically instantiates the writer class configured via properties. Throws an IllegalStateException for missing or invalid configuration.

Returns:

singleton instance of this dispatcher

addReplayRecord

public void addReplayRecord(String messageId,
 Map<String,Object> metadata,
 byte[] data)

Adds a replay record to the internal buffer queue for later asynchronous writing. If the queue is full, drops the message and logs drop occurrences at configured frequency.

Parameters:

messageId - unique identifier of the message

metadata - metadata map describing contextual information of the message

data - raw byte array of the message content

addReplayRecord

public void addReplayRecord(ByteBuffer dataBuffer,
 int byteWritten,
 String messageId,
 Map<String,Object> metadata)

Convenience method to wrap data in ByteBuffer and delegate to addReplayRecord(String, byte[], Map).

Parameters:

dataBuffer - byte buffer containing the raw message data

byteWritten - number of bytes written to the buffer

messageId - unique message identifier

metadata - metadata map for contextual information
