Method Detail

init

public void init(Config cfg)

Description copied from interface: MessageDeSerializer

Initialize the deserializer

Specified by:

init in interface MessageDeSerializer

Parameters:

cfg - configuration

build

public void build(java.lang.Object partialObject,
                  int edge)

Builds the message from the data buffers in the partialObject. Since this method supports multi-messages it iterates through the buffers and builds all the messages separately

Specified by:

build in interface MessageDeSerializer

Parameters:

partialObject - message object that needs to be built

edge - the edge value associated with this message

getDataBuffers

public java.lang.Object getDataBuffers(java.lang.Object partialObject,
                                       int edge)

Description copied from interface: MessageDeSerializer

Returns the data buffers for the given message.

Specified by:

getDataBuffers in interface MessageDeSerializer

Parameters:

partialObject - object that contains the buffers

edge - id of the edge

Returns:

if single message and not keyed returns the data. if keyed returns a pair of {key,data}. if there are multiple sub messages returns a list of data object for non keyed and a list of {key,data} for keyed operations

buildHeader

public MessageHeader buildHeader(DataBuffer buffer,
                                 int edge)

Builds the header object from the data in the data buffer

Specified by:

buildHeader in interface MessageDeSerializer

Parameters:

buffer - data buffer that contains the message

edge - the edge value associated with this message

Returns:

the built message header object
