Field Detail

m_nTypeId

protected final int m_nTypeId
The type identifier of the user type to serialize and deserialize.

Constructor Detail

PortableObjectSerializer

public PortableObjectSerializer(int nTypeId)
Create a new PortableObjectSerializer for the user type with the given type identifier.
Parameters:
nTypeId - the user type identifier

Method Detail

serialize

public void serialize(PofWriter out,
                      Object o)
               throws IOException
Serialize a user type instance to a POF stream by writing its state using the specified PofWriter object. <p/> An implementation of PofSerializer is required to follow the following steps in sequence for writing out an object of a user type:
  1. If the object is evolvable, the implementation must set the version by calling PofWriter.setVersionId(int).
  2. The implementation may write any combination of the properties of the user type by using the "write" methods of the PofWriter, but it must do so in the order of the property indexes.
  3. After all desired properties of the user type have been written, the implementation must terminate the writing of the user type by calling PofWriter.writeRemainder(com.tangosol.util.Binary).
Specified by:
serialize in interface PofSerializer
Parameters:
out - the PofWriter with which to write the object's state
o - the object to serialize
Throws:
IOException - if an I/O error occurs

deserialize

public Object deserialize(PofReader in)
                   throws IOException
Deserialize a user type instance from a POF stream by reading its state using the specified PofReader object. <p/> An implementation of PofSerializer is required to follow the following steps in sequence for reading in an object of a user type:
  1. If the object is evolvable, the implementation must get the version by calling PofWriter.getVersionId().
  2. The implementation may read any combination of the properties of the user type by using "read" methods of the PofReader, but it must do so in the order of the property indexes.
  3. After all desired properties of the user type have been read, the implementation must terminate the reading of the user type by calling PofReader.readRemainder().
Specified by:
deserialize in interface PofSerializer
Parameters:
in - the PofReader with which to read the object's state
Returns:
the deserialized user type instance
Throws:
IOException - if an I/O error occurs

initialize

public void initialize(PortableObject portable,
                       PofReader in)
                throws IOException
Initialize the specified (newly instantiated) PortableObject instance using the specified reader.
Parameters:
portable - the object to initialize
in - the PofReader with which to read the object's state
Throws:
IOException - if an I/O error occurs
