org.eclipse.team.core.mapping.ResourceMappingMerger
- All Implemented Interfaces:
IResourceMappingMerger
- Direct Known Subclasses:
AbstractResourceMappingMerger
Abstract implementation of
IResourceMappingMerger
. This merger
delegates the merge of all resources covered by the mappings of the
model provider returned from getModelProvider()
back to the
merge context. Subclasses should override the merge(IMergeContext, IProgressMonitor)
method in order to change this behavior.
Clients may subclass this class.

validateMerge
Description copied from interface:IResourceMappingMerger
Validate an auto-merge for the given context. This method must be invoked for all mergers involved in the merge before the auto-merge is attempted. The purpose of the validation is to indicate whether there are conditions in the merge context that make an auto-merge undesirable. The purpose is not to indicate that conflicts exist (this is done by themerge
method) but instead to indicate that the nature of one of more incoming changes is such that performing an auto-merge may be undesirable.Clients should validate before performing the merge and, if any of the returned status are not OK, should prompt the user to make them aware of the potential side effects. The user may still decide to attempt an auto-merge, in which case the client may still invoke the
merge
method.- Specified by:
validateMerge
in interfaceIResourceMappingMerger
- Parameters:
mergeContext
- a context that provides access to the resources involved in the merge. The context must not benull
.monitor
- a progress monitor- Returns:
- a status indicating any potential side effects of performing an auto-merge.
-
getModelProvider
Return the model provider associated with this merger.- Returns:
- Return the model provider associated with this merger.
-
getMergeRule
Return the scheduling rule required to merge all the changes in the context for the model provider of this merger. By default, return a rule that covers all the projects for the mappings that belong to the model provider of this merger.- Specified by:
getMergeRule
in interfaceIResourceMappingMerger
- Parameters:
context
- the context that contains the changes to be merged- Returns:
- the scheduling rule required by this merger to merge all the changes in the given context belonging to the merger's model provider.

merge
in interfaceIResourceMappingMerger
- Parameters:
