                      int numberOfNodeMetas)

Method Detail

serialize

public void serialize(DataOutput out,
                      BTreeMap.BNode value)
               throws IOException

Description copied from interface: Serializer

Serialize the content of an object into a ObjectOutput

Specified by:

serialize in interface Serializer<BTreeMap.BNode>

Parameters:

out - ObjectOutput to save object into

value - Object to serialize

Throws:

IOException

deserialize

public BTreeMap.BNode deserialize(DataInput in,
                                  int available)
                           throws IOException

Description copied from interface: Serializer

Deserialize the content of an object from a DataInput.

Specified by:

deserialize in interface Serializer<BTreeMap.BNode>

Parameters:

in - to read serialized data from

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

Returns:

deserialized object

Throws:

IOException

fixedSize

public int fixedSize()

Description copied from interface: Serializer

Data could be serialized into record with variable size or fixed size. Some optimizations can be applied to serializers with fixed size

Specified by:

fixedSize in interface Serializer<BTreeMap.BNode>

Returns:

fixed size or -1 for variable size
