Member Function Documentation

virtual void co::ObjectHandler::deregisterObject ( Object *  object )

pure virtual

Deregister a distributed object.

Parameters

object

the object instance.

Version

1.0

Implemented in co::LocalNode.

virtual uint32_t co::ObjectHandler::mapObjectNB ( Object *  object, const UUID &  id, const uint128_t &  version, NodePtr  master  )

pure virtual

Start mapping a distributed object.

Parameters

object	the object to map.
id	the object identifier
version	the version to map.
master	the master node, may be invalid/0.

Returns

the request identifier for mapObjectSync().

Version

1.0

Implemented in co::LocalNode.

virtual bool co::ObjectHandler::mapObjectSync ( const uint32_t  requestID )

pure virtual

Finalize the mapping of a distributed object.

Version

1.0

Implemented in co::LocalNode.

virtual bool co::ObjectHandler::registerObject ( Object *  object )

pure virtual

Register a distributed object.

Registering a distributed object makes this object the master version. The object's identifier is used to map slave instances of the object. Master versions of objects are typically writable and can commit new versions of the distributed object.

Parameters

object

the object instance.

Returns

true if the object was registered, false otherwise.

Version

1.0

Implemented in co::LocalNode.

CO_API void co::ObjectHandler::releaseObject

(

Object *

object

)

Convenience method to deregister or unmap an object.

Version

1.0

virtual void co::ObjectHandler::unmapObject ( Object *  object )

pure virtual

Unmap a mapped object.

Version

1.0

Implemented in co::LocalNode.
