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.

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 -
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
