apply
public boolean apply(IMergeCriterion criterion)
Description copied from class:AbstractMerger
Default implementation of apply for mergers that extends this class. Will acceptnull
or AdditiveMergeCriterion.INSTANCE.- Specified by:
apply
in interfaceIMergeCriterionAware
- Overrides:
apply
in classResourceAttachmentChangeMerger
- Parameters:
criterion
- The merge criterion- Returns:
true
if the given criterion is null or is AdditiveMergeCriterion.INSTANCE.
-
copyRightToLeft
public void copyRightToLeft(Diff target, Monitor monitor)
Description copied from class:AbstractMerger
Executes the copy from right to left.- Specified by:
copyRightToLeft
in interfaceIMerger
- Overrides:
copyRightToLeft
in classAbstractMerger
- Parameters:
target
- The difference to handle.monitor
- Monitor.- See Also:
IMerger.copyRightToLeft(org.eclipse.emf.compare.Diff, org.eclipse.emf.common.util.Monitor)
-
getDirectMergeDependencies
public Set<Diff> getDirectMergeDependencies(Diff diff, boolean mergeRightToLeft)
Description copied from class:AbstractMerger
Retrieves the set of directly required diffs needed in order to merge the current one. This may includes the diff'srequirements
or any other diff that we need to merge before the given one.- Specified by:
getDirectMergeDependencies
in interfaceIMerger2
- Overrides:
getDirectMergeDependencies
in classAbstractMerger
- Parameters:
diff
- The diff which direct requirements we need.mergeRightToLeft
- The direction in which we're considering a merge.- Returns:
- The set of directly required diffs in order to merge the current one.
-
getDirectResultingMerges
public Set<Diff> getDirectResultingMerges(Diff diff, boolean mergeRightToLeft)
Description copied from class:AbstractMerger
Returns all differences that will be merged because of our merging the giventarget
difference. This may include the diff'simplications
, the diff'sequivalences
, the diff'srefinements
or any other diff that we need to merge together with the given diff.- Specified by:
getDirectResultingMerges
in interfaceIMerger2
- Overrides:
getDirectResultingMerges
in classAbstractMerger
- Parameters:
diff
- The difference we're considering merging.mergeRightToLeft
- The direction in which we're considering a merge.- Returns:
- The Set of all differences that will be merged because we've merged
target
.
