public class ThreeWayComparisonGroupProvider
extends AbstractDifferenceGroupProvider

This implementation of a IDifferenceGroupProvider will be used to group the differences by their side : left, right and conflicts.

The table below describes the location of a diff depending on its status and that of its refining diffs (whether all or some of them are in a real/pseudo conflict).

	Real Conflicts		Pseudo-Conflicts		No Conflict
	All	Some	All	Some	All
Tech. filter ON	Conflict	Conflict	Conflict (hidden)	Side	Side
Tech. filter OFF	Conflict	Conflict	Conflict	Side	Side

Since:

4.0

Field Details

DEFAULT_DIFF_GROUP_FILTER_PREDICATE

public static final com.google.common.base.Predicate<? super Diff> DEFAULT_DIFF_GROUP_FILTER_PREDICATE

The default predicate used to filter differences in difference groups. The predicate returns true for diffs that do not have a direct or indirect real conflict and that do not have only pseudo conflicts.

public ThreeWayComparisonGroupProvider()

Method Details

isEnabled

public boolean isEnabled(IComparisonScope scope,
 Comparison comparison)

Returns the activation condition based on the scope and comparison objects.

Specified by:

isEnabled in interface IDifferenceGroupProvider

Overrides:

isEnabled in class AbstractDifferenceGroupProvider

Parameters:

scope - The scope on which the group provider will be applied.

comparison - The comparison which is to be displayed in the structural view.

Returns:

The activation condition based on the scope and comparison objects.

See Also:

• IDifferenceGroupProvider.isEnabled(org.eclipse.emf.compare.scope.IComparisonScope, org.eclipse.emf.compare.Comparison)

buildGroups

protected Collection<? extends IDifferenceGroup> buildGroups(Comparison comparison2)

Description copied from class: AbstractDifferenceGroupProvider

Builds the groups for this comparison. The framework expects that all groups are fully initialized ( their sub tree should be built). Extending IDifferenceGroupProvider2 needs to override this method to provid groups.

Overrides:

buildGroups in class AbstractDifferenceGroupProvider

Parameters:

comparison2 - comparison against which the groups will be built.

Returns:

Newly built collections of IDifferenceGroup.
