Method Summary

Modifier and Type	Method	Description
ParameterValue	deserialize(DataInputStream stream, ColumnDefinition cd)	Read one column value (i.e. a cell from the stream) The enums are deserialized as shorts (it is converted to the actual type in the TableDefinition.deserialize(byte[], byte[]))
ParameterValue	deserialize(ByteBuffer byteBuf, ColumnDefinition cd)	Same as above but read the data from a ByteBuffer.
T	fromByteArray(byte[] b, ColumnDefinition cd)	this method deserializes the value from a byte array
void	serialize(DataOutputStream stream, ParameterValue pv)
void	serialize(ByteBuffer byteBuf, ParameterValue pv)	Same as above but serialize into a bytebuffer.
byte[]	toByteArray(T v)	This method serializes the value into a byte array
Db.ParameterValue	toProto(ParameterValue pv)

Method Detail

deserialize

public ParameterValue deserialize(DataInputStream stream,
                                  ColumnDefinition cd)
                           throws IOException

Description copied from interface: ColumnSerializer

Read one column value (i.e. a cell from the stream) The enums are deserialized as shorts (it is converted to the actual type in the TableDefinition.deserialize(byte[], byte[]))

Parameters:

stream - - data stream used for the input

cd - the column definition for the involved column (can be used to look up column name or other properties to help in deserialization)

Returns:

the deserialized value

Throws:

IOException

deserialize

public ParameterValue deserialize(ByteBuffer byteBuf,
                                  ColumnDefinition cd)
                           throws IOException

Description copied from interface: ColumnSerializer

Same as above but read the data from a ByteBuffer.

If the buffer is not long enough, it throws an BufferUnderflowException.

Returns:

Throws:

IOException

serialize

public void serialize(DataOutputStream stream,
                      ParameterValue pv)
               throws IOException

Throws:

IOException

serialize

public void serialize(ByteBuffer byteBuf,
                      ParameterValue pv)

Description copied from interface: ColumnSerializer

Same as above but serialize into a bytebuffer. If the ByteBuffer is not large enough, a BufferOverflowException will be thrown.

toProto

public Db.ParameterValue toProto(ParameterValue pv)

fromByteArray

public T fromByteArray(byte[] b,
                       ColumnDefinition cd)
                throws IOException

Description copied from interface: ColumnSerializer

this method deserializes the value from a byte array

Specified by:

fromByteArray in interface ColumnSerializer<T>

Parameters:

b - the input byte array

cd - the column definition for the involved column (can be used to look up column name or other properties to help in deserialization)

Returns:

the deserialized value

Throws:

IOException

toByteArray

public byte[] toByteArray(T v)

Description copied from interface: ColumnSerializer

This method serializes the value into a byte array

Specified by:

toByteArray in interface ColumnSerializer<T>

Returns:

the resulting byte array
