Method Detail

serialize

public void serialize(DataOutput out,
             Boolean value)
               throws IOException

Description copied from class: Serializer

Serialize the content of an object into a ObjectOutput

Specified by:

serialize in class Serializer<Boolean>

Parameters:

out - ObjectOutput to save object into

value - Object to serialize

Throws:

IOException - in case of IO error

deserialize

public Boolean deserialize(DataInput in,
                  int available)
                    throws IOException

Description copied from class: Serializer

Deserialize the content of an object from a DataInput.

Specified by:

deserialize in class Serializer<Boolean>

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 - in case of IO error

fixedSize

public int fixedSize()

Description copied from class: Serializer

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

Overrides:

fixedSize in class Serializer<Boolean>

Returns:

fixed size or -1 for variable size

isTrusted

public boolean isTrusted()

Description copied from class: Serializer

MapDB has relax record size boundary checking. It expect deserializer to read exactly as many bytes as were writen during serialization. If deserializer reads more bytes it might start reading others record data in store.

Some serializers (Kryo) have problems with this. To prevent this we can not read data directly from store, but must copy them into separate byte[]. So zero copy optimalizations is disabled by default, and must be explicitly enabled here.

This flag indicates if this serializer was 'verified' to read as many bytes as it writes. It should be also much better tested etc.

Overrides:

isTrusted in class Serializer<Boolean>

Returns:

true if this serializer is well tested and writes as many bytes as it reads.

valueArraySerialize

public void valueArraySerialize(DataOutput out,
                       Object vals)
