Method Detail

serialize

public void serialize(DataOutput2 out,
                      java.lang.Integer value)
               throws java.io.IOException

Description copied from interface: Serializer

Serializes the content of the given value into the given DataOutput2.

Specified by:

serialize in interface Serializer<java.lang.Integer>

Overrides:

serialize in class SerializerInteger

Parameters:

out - DataOutput2 to save object into

value - Object to serialize

Throws:

java.io.IOException - in case of an I/O error

deserialize

public java.lang.Integer deserialize(DataInput2 in,
                                     int available)
                              throws java.io.IOException

Description copied from interface: Serializer

Deserializes and returns the content of the given DataInput2.

Specified by:

deserialize in interface Serializer<java.lang.Integer>

Overrides:

deserialize in class SerializerInteger

Parameters:

in - DataInput2 to de-serialize data from

available - how many bytes that are available in the DataInput2 for reading, may be -1 (in streams) or 0 (null).

Returns:

the de-serialized content of the given DataInput2

Throws:

java.io.IOException - in case of an I/O error

valueArraySerialize

public void valueArraySerialize(DataOutput2 out,
                                java.lang.Object vals)
                         throws java.io.IOException

Specified by:

valueArraySerialize in interface GroupSerializer<java.lang.Integer>

Overrides:

valueArraySerialize in class SerializerFourByte<java.lang.Integer>

Throws:

java.io.IOException

valueArrayDeserialize

public int[] valueArrayDeserialize(DataInput2 in,
                                   int size)
                            throws java.io.IOException

Specified by:

valueArrayDeserialize in interface GroupSerializer<java.lang.Integer>

Overrides:

valueArrayDeserialize in class SerializerFourByte<java.lang.Integer>

Throws:

java.io.IOException

fixedSize

public int fixedSize()

Description copied from interface: Serializer

Returns the fixed size of the serialized form in bytes or -1 if the size is not fixed (e.g. for Strings).

Some optimizations can be applied to serializers with a fixed size.

Specified by:

fixedSize in interface Serializer<java.lang.Integer>

Overrides:

fixedSize in class SerializerFourByte<java.lang.Integer>

Returns:

the fixed size of the serialized form in bytes or -1 if the size is not fixed

                                  DataInput2 input,
                                  int keysLen,
                                  java.util.Comparator comparator)
                           throws java.io.IOException

Specified by:

valueArrayBinarySearch in interface GroupSerializer<java.lang.Integer>

Overrides:

valueArrayBinarySearch in class SerializerInteger

Throws:

java.io.IOException

valueArrayBinaryGet

                                             int pos)
                                      throws java.io.IOException

Specified by:

valueArrayBinaryGet in interface GroupSerializer<java.lang.Integer>

Overrides:

valueArrayBinaryGet in class SerializerFourByte<java.lang.Integer>

Throws:

java.io.IOException
