Method Detail

assign

public DeltaMVRegister assign(SerializableType element)

contains

public boolean contains(SerializableType element)

get

public Set<SerializableType> get()

reset

public DeltaMVRegister reset()

copy

public GenericCRDT copy()

Description copied from interface: GenericCRDT

Creates a copy of the CRDT. Modifications on the copy don't modify the original.

Returns:

a copy of the CRDT

getCausalContext

public CausalContext getCausalContext()

serialize

public void serialize(io.netty.buffer.ByteBuf in)
               throws IOException

Description copied from interface: GenericCRDT

Serializes the CRDT into a ByteBuf

Parameters:

in - ByteBuf to serialize the CRDT to

Throws:

IOException - if an error occurs while serializing

generateDelta

public DeltaMVRegister generateDelta(VersionVector vv)

Description copied from interface: DeltaCRDT

Calculates a delta from a given version for the current state

Specified by:

generateDelta in interface DeltaCRDT

Specified by:

generateDelta in class DeltaCausalBasedCRDT

Parameters:

vv - a version version to calculate the delta from

Returns:

a delta for the current state

mergeDelta

public DeltaMVRegister mergeDelta(DeltaBasedCRDT delta)

Description copied from interface: DeltaCRDT

Applies a delta to the current state. This method is analogous to a merge of states

Specified by:

mergeDelta in interface DeltaCRDT

Specified by:

mergeDelta in class DeltaCausalBasedCRDT

Parameters:

delta - a crdt representing the delta

Returns:

the current state
