Enclosing class:

UnResolvedWeightedCallTargets

private static final class UnResolvedWeightedCallTargets.UnResolvedSingleTarget
extends UnResolvedWeightedCallTargets

An implementation for storing a call site distribution that has a single target.

target

private final MethodReference target

weight

private float weight

UnResolvedWeightedCallTargets.UnResolvedSingleTarget

UnResolvedWeightedCallTargets.UnResolvedSingleTarget(MethodReference t,
                                                     double w)

visitTargets

public void visitTargets(UnResolvedWeightedCallTargets.Visitor func)

Description copied from class: UnResolvedWeightedCallTargets

Iterate over all of the targets, evaluating the argument function on each edge. NOTE: We guarantee that the targets will be iterated in monotonically decreasing edge weight. This simplifies the coding of the inlining clients that consume this information.

Specified by:

visitTargets in class UnResolvedWeightedCallTargets

Parameters:

func - the function to evaluate on each target

augmentCount

public UnResolvedWeightedCallTargets augmentCount(MethodReference t,
                                                  double v)

Description copied from class: UnResolvedWeightedCallTargets

Augment the weight associated with the argument method by the argument amount. NOTE: This method may change the representation of the target method. The caller must be sure to update their backing store of UnResolvedWeightedCallTargets accordingly to avoid losing the update.

Specified by:

augmentCount in class UnResolvedWeightedCallTargets

decay

public void decay(double rate)

Description copied from class: UnResolvedWeightedCallTargets

Decay the weights of all call targets by the specified amount

Specified by:

decay in class UnResolvedWeightedCallTargets

Parameters:

rate - the value to decay by

totalWeight

public double totalWeight()

Description copied from class: UnResolvedWeightedCallTargets

totalWeight of all call targets

Specified by:

totalWeight in class UnResolvedWeightedCallTargets

filter

public UnResolvedWeightedCallTargets filter(MethodReference goal)

Specified by:

filter in class UnResolvedWeightedCallTargets

Parameters:

goal - MethodReference that is the only statically possible target

Returns:

the filtered call targets or null if no such target exists
