Method Detail

newByteBuffer

public static DataClayByteBuffer newByteBuffer()

Creates a new byte buffer

Returns:

New byte buffer

newByteBuffer

public static DataClayByteBuffer newByteBuffer(DataClayByteArray byteArray)

Creates a new byte buffer with bytes provided

Parameters:

byteArray - Byte array containing bytes

Returns:

Byte buffer to read bytes.

createMetaData

public static DataClayObjectMetaData createMetaData(IdentityHashMap<Object,Integer> curSerObjs,
                                                    ExecutionEnvironmentID hintForMissing,
                                                    int numRefsPointingToObj,
                                                    ObjectID origObjectID,
                                                    ExecutionEnvironmentID rootLocation,
                                                    ExecutionEnvironmentID theoriginLocation,
                                                    Set<ExecutionEnvironmentID> thereplicaLocations,
                                                    String thealias,
                                                    boolean theisReadOnly)

This function creates a metadata of an object

Parameters:

curSerObjs - Currently found objects during serialization

hintForMissing - Hint for associations without hint (for MakePersistent)

numRefsPointingToObj - Number of references pointing to object.

thealias - Alias of the object or null if none

origObjectID - Original object id in case of new version

rootLocation - root location of the object

theoriginLocation - origin location of the object in case of replica

thereplicaLocations - IDs of locations this object was replicated to

theisReadOnly - indicates if object is read only

Returns:

MetaData created.

serializeBinary

public static byte[] serializeBinary(Object o)
                              throws IOException

Throws:

IOException

deserializeBinary

public static Object deserializeBinary(byte[] data)
                                throws Exception

Reads a binary-serialized object from a byte array

Parameters:

data - containing the serialized object

Returns:

the object read from the data

Throws:

Exception
