Member Function Documentation

void addProtect (    )  [inline]

Sets the node as protected (actually increments a protection counter). When the node is protected, no notifications are sent to it. Definition at line 108 of file mlinknode.h. Referenced by connect(), disconnect(), disconnectAll(), release(), and reserve().

StsLnNB connect (  LinkNode const &    other )

Creates a bi-directional connection between this and the other node. Definition at line 16 of file mlinknode.cc. References addProtect(), and removeProtect().

StsLnNd disconnect (  LinkNode const &    other, IndLnNd    iOther )

Disconnects the connection in both directions. Definition at line 26 of file mlinknode.cc. References addProtect(), getHost(), and removeProtect(). Referenced by disconnectAll().

void disconnectAll (    )

Disconnects all connections. Definition at line 87 of file mlinknode.cc. References addProtect(), disconnect(), iterConnection(), and removeProtect(). Referenced by SuspendLinkNodeNotify::releaseAll().

NodeLink const* findConnection (  LinkNode const &    item )  const [inline]

Finds and returns the NodeLink object connecting this node to the other given node. Definition at line 125 of file mlinknode.h.

virtual CPtr getHost (  ClassName    className )  const [inline, virtual]

Returns the owner object for the node, in case the node is owned as an attribute, not inherited. If it is inherited, returns pointer to itself. Reimplemented in IndirLinkNode. Definition at line 139 of file mlinknode.h. Referenced by disconnect().

Bool isConnected (  ClassName    clsName )  const

Is the node connected to any LinkNode belonging to the given class? Definition at line 104 of file mlinknode.cc.

Bool isConnected (  IndLnNd    iOther )  const [inline]

Is the node connected to any other LinkNode. Definition at line 93 of file mlinknode.h.

NodeLink const* iterConnection (  LinkNodeIndex &    i )  const [inline]

Connection iteration. Returns NULL when the value is over... Definition at line 116 of file mlinknode.h. Referenced by disconnectAll().

StsLnNd release (  IndLnNd    iOther )

Releases a reservation, but does not disconnect the other object. Definition at line 71 of file mlinknode.cc. References addProtect(), removeProtect(), and setReleasedBy().

void releaseAll (    )

Releases all connections, but does not disconnect them. Reimplemented in SuspendLinkNodeNotify.

void removeProtect (    )

Removes protection from the node (decrements a protection counter). Definition at line 262 of file mlinknode.cc. Referenced by connect(), disconnect(), disconnectAll(), release(), and reserve().

StsLnNd reserve (  LinkNode const &    other )

Creates a connection that reserves the other object. Reservation implies an ownership relation (reserver owns the reservee). Definition at line 53 of file mlinknode.cc. References addProtect(), and removeProtect().
