Detailed Description

Move node selector is an abstraction to ready operation list in a list scheduler.

MoveNodeSelectors are responsible in maintaining the ready list and updating it according to scheduling progress.

Member Function Documentation

candidates()

MoveNodeGroup MoveNodeSelector::candidates ( )

pure virtual

Returns a group of move nodes which should be scheduled next.

By default returns an empty group. A non-empty group is guaranteed to contain at least one unscheduled move, but not all of them necessarily are.

Returns

Move node group.

Implemented in DDGMoveNodeSelector< PQType >, CriticalPathBBMoveNodeSelector, BUMoveNodeSelector, and SequentialMoveNodeSelector.

Definition at line 58 of file MoveNodeSelector.cc.

                             {
    return MoveNodeGroup();
}

mightBeReady()

void MoveNodeSelector::mightBeReady ( MoveNode &  node )

pure virtual

This should be called by the client when some incoming dependence to a moveNode is removed.

Parameters

node	Node which has lost some incoming dependence

Implemented in DDGMoveNodeSelector< PQType >, CriticalPathBBMoveNodeSelector, BUMoveNodeSelector, and SequentialMoveNodeSelector.

Definition at line 82 of file MoveNodeSelector.cc.

                                          {
    assert(false && "Should never be called. Here just to avoid warning.");
}

notifyScheduled()

void MoveNodeSelector::notifyScheduled ( MoveNode &  node )

pure virtual

This should be called by the client as soon as a MoveNode is scheduled in order to update the internal state of the selector.

Parameters

node	The scheduled MoveNode.

Implemented in DDGMoveNodeSelector< PQType >, CriticalPathBBMoveNodeSelector, BUMoveNodeSelector, and SequentialMoveNodeSelector.

Definition at line 70 of file MoveNodeSelector.cc.
