ByteBuffer
. Position of buffer should be
set before calling of given method. Serialization result is compatible with result of call of
OBinarySerializer.serializeNativeObject(Object, byte[], int, Object...)
method. So if we call:
buffer.position(10);
binarySerializer.serializeInByteBufferObject(object, buffer);
and then
byte[] stream = new byte[serializedSize + 10];
buffer.position(10);
buffer.get(stream);
following assert should pass
assert object.equals(binarySerializer.deserializeNativeObject(stream, 10))
Final position of ByteBuffer
will be changed and will be equal to sum of
buffer start position and value returned by method OBinarySerializer.getObjectSize(Object, Object...)

- Buffer which will contain serialized presentation of buffer.hints
- Type (types in case of composite object) of object.public Float deserializeFromByteBufferObject(ByteBuffer buffer)

So if we call
byte[] stream = new byte[serializedSize];
binarySerializer.serializeNativeObject(object, stream, 0);
following assert should pass
byteBuffer.position(10);
byteBuffer.put(stream);
byteBuffer.position(10);
assert object.equals(binarySerializer.deserializeFromByteBufferObject(buffer))
Final position of ByteBuffer
will be changed and will be equal to sum of

.
Binary format of method is expected to be the same as binary format of method OBinarySerializer.serializeNativeObject(Object, byte[], int, Object...)
. So if we call:
byte[] stream = new byte[serializedSize];
binarySerializer.serializeNativeObject(object, stream, 0);
walChanges.setBinaryValue(buffer, stream, 10);
Then following assert should pass
assert object.equals(binarySerializer.deserializeFromByteBufferObject(buffer, walChanges, 10));
