Detailed Description

template<class parent_type>
class RakNet::Replica3Composite< parent_type >

Use Replica3 through composition instead of inheritance by containing an instance of this templated class Calls to parent class for all functions Parent class must still define and functions though!

Precondition
Parent class must call SetCompositeOwner() on this object

Member Function Documentation

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::DeallocReplica ( RakNet::Connection_RM3 sourceConnection)
inlinevirtual

Override with {delete this;}.

  1. Got a remote message to delete this object which passed DeserializeDestruction(), OR
  2. ReplicaManager3::SetAutoManageConnections() was called autoDestroy true (which is the default setting), and a remote system that owns this object disconnected) OR <>
    Override with {delete this;} to actually delete the object (and any other processing you wish).
    If you don't want to delete the object, just do nothing, however, the system will not know this so you are responsible for deleting it yoruself later.
    destructionBitstream may be 0 if the object was deleted locally

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::Deserialize ( RakNet::DeserializeParameters *  deserializeParameters)
inlinevirtual

Read what was written in Serialize()

Reads the contents of the class from SerializationParamters::serializationBitstream.
Called whenever Serialize() is called with different data from the last send.

Parameters
[in]serializationBitstreamBitstream passed to Serialize()
[in]timeStamp0 if unused, else contains the time the message originated on the remote system
[in]sourceConnectionWhich system sent to us

Implements RakNet::Replica3.

template<class parent_type >
virtual bool RakNet::Replica3Composite< parent_type >::DeserializeConstruction ( RakNet::BitStream constructionBitstream,
RakNet::Connection_RM3 sourceConnection 
)
inlinevirtual

Read data written by Replica3::SerializeConstruction()

Reads whatever data was written to constructionBitstream in Replica3::SerializeConstruction()

Parameters
[out]constructionBitstreamBitstream written to in Replica3::SerializeConstruction()
[in]sourceConnectionSystem that sent us this network message.
Returns
true to accept construction of the object. false to reject, in which case the object will be deleted via Replica3::DeallocReplica()

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::DeserializeConstructionExisting ( RakNet::BitStream constructionBitstream,
RakNet::Connection_RM3 sourceConnection 
)
inlinevirtual

Same as DeserializeConstruction(), but for an object that already exists on the remote system. Used if you return RM3CS_ALREADY_EXISTS_REMOTELY from QueryConstruction

Reimplemented from RakNet::Replica3.

template<class parent_type >
virtual bool RakNet::Replica3Composite< parent_type >::DeserializeDestruction ( RakNet::BitStream destructionBitstream,
RakNet::Connection_RM3 sourceConnection 
)
inlinevirtual

Read data written by Replica3::SerializeDestruction()

Return true to delete the object. BroadcastDestruction() will be called automatically, followed by ReplicaManager3::Dereference.
Return false to not delete it. If you delete it at a later point, you are responsible for calling BroadcastDestruction() yourself.

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::PostDeserializeConstruction ( RakNet::BitStream constructionBitstream,
RakNet::Connection_RM3 sourceConnection 
)
inlinevirtual

Called after DeserializeConstruction completes for all objects in a given update tick.
This is used to resolve dependency chains, where two objects would refer to each other in DeserializeConstruction, yet one had not been constructed yet In PostDeserializeConstruction(), you know that all objects have already been created, so can resolve NetworkIDs to pointers safely. You can also use it to trigger some sort of event when you know the object has completed deserialization.

Parameters
[in]constructionBitstreamBitStream written in PostSerializeConstruction()
[in]sourceConnectionSystem that sent us this network message.

Reimplemented from RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::PreDestruction ( RakNet::Connection_RM3 sourceConnection)
inlinevirtual

Called after DeserializeDestruction completes for the object successfully, but obviously before the object is deleted.
Override to trigger some sort of event when you know the object has completed destruction.

Parameters
[in]sourceConnectionSystem that sent us this network message.

Reimplemented from RakNet::Replica3.

template<class parent_type >
virtual RakNet::RM3ActionOnPopConnection RakNet::Replica3Composite< parent_type >::QueryActionOnPopConnection ( RakNet::Connection_RM3 droppedConnection) const
inlinevirtual

The system is asking what to do with this replica when the connection is dropped.

Return QueryActionOnPopConnection_Client, QueryActionOnPopConnection_Server, or QueryActionOnPopConnection_PeerToPeer

Implements RakNet::Replica3.

template<class parent_type >
virtual RakNet::RM3ConstructionState RakNet::Replica3Composite< parent_type >::QueryConstruction ( RakNet::Connection_RM3 destinationConnection,
RakNet::ReplicaManager3 replicaManager3 
)
inlinevirtual

Ask if this object, which does not exist on destinationConnection should (now) be sent to that system.

If ReplicaManager3::QueryConstructionMode() returns QUERY_CONNECTION_FOR_REPLICA_LIST or QUERY_REPLICA_FOR_CONSTRUCTION_AND_DESTRUCTION (default), then QueyrConstruction() is called once per tick from ReplicaManager3::Update() to determine if an object should exist on a given system.
Based on the return value, a network message may be sent to the other system to create the object.
If QueryConstructionMode() is overriden to return QUERY_CONNECTION_FOR_REPLICA_LIST, this function is unused.

Note
Defaults are provided: QueryConstruction_PeerToPeer(), QueryConstruction_ServerConstruction(), QueryConstruction_ClientConstruction(). Return one of these functions for a working default for the relevant topology.
Parameters
[in]destinationConnectionWhich system we will send to
[in]replicaManager3Plugin instance for this Replica3
Returns
What action to take

Implements RakNet::Replica3.

template<class parent_type >
virtual RakNet::RM3DestructionState RakNet::Replica3Composite< parent_type >::QueryDestruction ( RakNet::Connection_RM3 destinationConnection,
RakNet::ReplicaManager3 replicaManager3 
)
inlinevirtual

Ask if this object, which does exist on destinationConnection should be removed from the remote system.

If ReplicaManager3::QueryConstructionMode() returns QUERY_REPLICA_FOR_CONSTRUCTION_AND_DESTRUCTION (default), then QueryDestruction() is called once per tick from ReplicaManager3::Update() to determine if an object that exists on a remote system should be destroyed for a given system.
Based on the return value, a network message may be sent to the other system to destroy the object.
Note that you can also destroy objects with BroadcastDestruction(), so this function is not useful unless you plan to delete objects for only a particular connection.
If QueryConstructionMode() is overriden to return QUERY_CONNECTION_FOR_REPLICA_LIST, this function is unused.

Parameters
[in]destinationConnectionWhich system we will send to
[in]replicaManager3Plugin instance for this Replica3
Returns
What action to take. Only RM3CS_SEND_DESTRUCTION does anything at this time.

Reimplemented from RakNet::Replica3.

template<class parent_type >
virtual bool RakNet::Replica3Composite< parent_type >::QueryRemoteConstruction ( RakNet::Connection_RM3 sourceConnection)
inlinevirtual

We're about to call DeserializeConstruction() on this Replica3. If QueryRemoteConstruction() returns false, this object is deleted instead.

By default, QueryRemoteConstruction_ServerConstruction() does not allow clients to create objects. The client will get Replica3::DeserializeConstructionRequestRejected().
If you want the client to be able to potentially create objects for client/server, override accordingly.
Other variants of QueryRemoteConstruction_* just return true.

Note
Defaults are provided: QueryRemoteConstruction_PeerToPeer(), QueryRemoteConstruction_ServerConstruction(), QueryRemoteConstruction_ClientConstruction(). Return one of these functions for a working default for the relevant topology.
Parameters
[in]sourceConnectionWhich system sent us the object creation request message.
Returns
True to allow the object to pass onto DeserializeConstruction() (where it may also be rejected), false to immediately reject the remote construction request

Implements RakNet::Replica3.

template<class parent_type >
virtual RakNet::RM3QuerySerializationResult RakNet::Replica3Composite< parent_type >::QuerySerialization ( RakNet::Connection_RM3 destinationConnection)
inlinevirtual

Implement with QuerySerialization_ClientSerializable(), QuerySerialization_ServerSerializable(), or QuerySerialization_PeerToPeer()

QuerySerialization() is a first pass query to check if a given object should serializable to a given system. The intent is that the user implements with one of the defaults for client, server, or peer to peer.
Without this function, a careless implementation would serialize an object anytime it changed to all systems. This would give you feedback loops as the sender gets the same message back from the recipient it just sent to.
If more than one system can serialize the same object then you will need to override to return true, and control the serialization result from Replica3::Serialize(). Be careful not to send back the same data to the system that just sent to you!

Returns
True to allow calling Replica3::Serialize() for this connection, false to not call.

Implements RakNet::Replica3.

template<class parent_type >
virtual RakNet::RM3SerializationResult RakNet::Replica3Composite< parent_type >::Serialize ( RakNet::SerializeParameters serializeParameters)
inlinevirtual

Serialize our class to a bitstream.

User should implement this function to write the contents of this class to SerializationParamters::serializationBitstream.
If data only needs to be written once, you can write it to SerializeConstruction() instead for efficiency.
Transmitted over the network if it changed from the last time we called Serialize().
Called every time the time interval to ReplicaManager3::SetAutoSerializeInterval() elapses and ReplicaManager3::Update is subsequently called.

Parameters
in/out]serializeParameters Parameters controlling the serialization, including destination bitstream to write to
Returns
Whether to serialize, and if so, how to optimize the results

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::SerializeConstruction ( RakNet::BitStream constructionBitstream,
RakNet::Connection_RM3 destinationConnection 
)
inlinevirtual

Write data to be sent only when the object is constructed on a remote system.

SerializeConstruction is used to write out data that you need to create this object in the context of your game, such as health, score, name. Use it for data you only need to send when the object is created.
After SerializeConstruction() is called, Serialize() will be called immediately thereafter. However, they are sent in different messages, so Serialize() may arrive a later frame than SerializeConstruction() For that reason, the object should be valid after a call to DeserializeConstruction() for at least a short time.

Note
The object's NetworkID and allocation id are handled by the system automatically, you do not need to write these values to constructionBitstream
Parameters
[out]constructionBitstreamDestination bitstream to write your data to
[in]destinationConnectionSystem that will receive this network message.

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::SerializeConstructionExisting ( RakNet::BitStream constructionBitstream,
RakNet::Connection_RM3 destinationConnection 
)
inlinevirtual

Same as SerializeConstruction(), but for an object that already exists on the remote system. Used if you return RM3CS_ALREADY_EXISTS_REMOTELY from QueryConstruction

Reimplemented from RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::SerializeDestruction ( RakNet::BitStream destructionBitstream,
RakNet::Connection_RM3 destinationConnection 
)
inlinevirtual

Write extra data to send with the object deletion event, if desired.

Replica3::SerializeDestruction() will be called to write any object destruction specific data you want to send with this event. destructionBitstream can be read in DeserializeDestruction()

Parameters
[out]destructionBitstreamBitstream for you to write to
[in]destinationConnectionSystem that will receive this network message.

Implements RakNet::Replica3.

template<class parent_type >
virtual void RakNet::Replica3Composite< parent_type >::WriteAllocationID ( RakNet::Connection_RM3 destinationConnection,
RakNet::BitStream allocationIdBitstream 
) const
inlinevirtual

Write a unique identifer that can be read on a remote system to create an object of this same class.

The value written to allocationIdBitstream will be passed to Connection_RM3::AllocReplica().
Sample implementation:
{allocationIdBitstream->Write(RakNet::RakString("Soldier");}

Parameters
[out]allocationIdBitstreamBitstream for the user to write to, to identify this class

Implements RakNet::Replica3.
