Method Detail

serialize

public void serialize(Object o,
                      ByteBuffer buffer)
               throws BufferOverflowException

Serializes the given BigInteger two's-complement byte array to the given buffer.

Specified by:

serialize in class DataType

Parameters:

o - serialize this object.

buffer - serialize o to this buffer.

Throws:

BufferOverflowException - if the serialized BigInteger instance is greater than the buffer's remaining space.

deserialize

public Object deserialize(ByteBuffer buffer)
                   throws BufferUnderflowException

De-serializes the BigInteger two's-complement byte array from the given buffer and constructs a BigInteger instance from that array. If the de-serialized byte array is of zero length, then returns null.

Specified by:

deserialize in class DataType

Parameters:

buffer - read in the BigInteger from this buffer.

Returns:

the de-serialized BigInteger instance. May return null.

Throws:

BufferUnderflowException - if buffer contains an incomplete BigInteger instance.

createSerializer

protected void createSerializer(MessageType.MessageField field,
                                String fieldName,
                                String indent,
                                Formatter output)

Generates runtime-compilable code for serializing a BigInteger message field.

Specified by:

createSerializer in class DataType

Parameters:

field - message field.

fieldName - BigInteger field name.

indent - indent generated code lines by this amount.

output - write generated code to this output.

createDeserializer

protected void createDeserializer(MessageType.MessageField field,
                                  String fieldName,
                                  String indent,
                                  Formatter output,
                                  boolean useBuilder)

Generates runtime-compilable code for de-serializing a BigInteger message field from a ByteBuffer.

Specified by:

createDeserializer in class DataType

Parameters:

field - message field.

fieldName - store de-serialized BigInteger instance into this field.

indent - indent generated code lines by this amount.

output - write generated code to this output.

useBuilder - if true then fieldName is a builder method name; otherwise a local variable.
