public class DisambiguationPolicy
extends ArrayList<DisambiguationPolicy.Level>

A disambiguation policy determines whether two disambiguation reports are still ambiguous or not.

The policy is basically a list of ResourceResolution instances each corresponding to either the resource itself of some of its parent in the hierarchy. Each of the ResourceResolution instances in the list determines how the appropriate part of the report is disambiguated.

                                       List<String> ambiguousTypeNames)

Parameters:

parentsDisambiguationStrategy -

ambiguousTypeNames - the list of ambiguous type names

Returns:

getParentsUpdateStrategy

public DisambiguationUpdateStrategy getParentsUpdateStrategy()

setParentsUpdateStrategy

public void setParentsUpdateStrategy(DisambiguationUpdateStrategy parentsUpdateStrategy)

getAmbiguousTypeNames

public List<String> getAmbiguousTypeNames()

Returns:

the list of type names that are defined in multiple plugins. Such type names should be disambiguated no matter if it is needed or not.

setAmbiguousTypeNames

public void setAmbiguousTypeNames(List<String> ambiguousTypeNames)

areAmbiguous

public <T> boolean areAmbiguous(MutableDisambiguationReport<T> a,
                       MutableDisambiguationReport<T> b)

Tells whether the last resolution in this policy determines the reports ambiguous.

Type Parameters:

T -

Parameters:

a -

b -

Returns:

getCurrentLevel

public DisambiguationPolicy.Level getCurrentLevel()

Returns:

the last element in this policy

getNext

public DisambiguationPolicy getNext()

If the user of this class determines that this policy can't disambiguate some list of reports, s/he can get the next policy to try by calling this method.

Returns:

the next policy in "chain" of possible policies

getNextRepartitioningPolicy

public DisambiguationPolicy getNextRepartitioningPolicy()

Returns:

a policy to be used to repartition unique reports using some other criteria or null if the current policy doesn't require repartitioning of unique reports.
