Class ThreeWayResourceComparator

java.lang.Object
org.eclipse.team.core.variants.ThreeWayResourceComparator
All Implemented Interfaces:
IResourceVariantComparator
public class ThreeWayResourceComparator extends Object implements IResourceVariantComparator
A resource comparator that uses the ThreeWaySynchronizer to compare local resources to their resource variants. The local state is determined using the local modification state and the remote state is determined by comparing the base bytes to the remote bytes obtained from the synchronizer.
Since:
3.0

    • ThreeWayResourceComparator

      public ThreeWayResourceComparator(ThreeWaySynchronizer synchronizer)
      Create a three-way resource comparator that uses the ThreeWaySynchronizer to compare a local resource to a resource variant.
      Parameters:
      synchronizer - The synchronizer to use.

    • compare

      public boolean compare(IResource local, IResourceVariant remote)
      Description copied from interface: IResourceVariantComparator
      Returns true if the local resource matches the remote resource based on this criteria and false otherwise. Comparing should be fast and based on cached information.
      Specified by:
      compare in interface IResourceVariantComparator
      Parameters:
      local - the local resource to be compared
      remote - the remote resources to be compared
      Returns:
      true if local and remote are equal based on this criteria and false otherwise.

    • compare

      public boolean compare(IResourceVariant base, IResourceVariant remote)
      Description copied from interface: IResourceVariantComparator
      Returns true if the base resource matches the remote resource based on this criteria and false otherwise. Comparing should be fast and based on cached information.
      Specified by:
      compare in interface IResourceVariantComparator
      Parameters:
      base - the base resource to be compared
      remote - the remote resources to be compared
      Returns:
      true if base and remote are equal based on this criteria and false otherwise.

    • isThreeWay

      public boolean isThreeWay()
      Description copied from interface: IResourceVariantComparator
      Answers true if the base tree is maintained by this comparator's subscriber. If the base tree is not considered than the subscriber can be considered as not supported three-way comparisons. Instead comparisons are made between the local and remote only without consideration for the base.
      Specified by:
      isThreeWay in interface IResourceVariantComparator
      Returns:
      whether this comparator is three-way or two-way
