Class ResolveDeltaCommand

java.lang.Object

com.ibm.xtools.comparemerge.emf.delta.deltaresolver.ResolveDeltaCommand

All Implemented Interfaces:

org.eclipse.emf.common.command.Command

public class ResolveDeltaCommand
extends java.lang.Object
implements org.eclipse.emf.common.command.Command

A ResolveDeltaCommand is used to resolve a delta in a merged resource with a resolution. The previous resolution is maintained in case the command is asked to undoIt.

Method Detail

reorderDeltas

protected java.util.List reorderDeltas(java.util.Set unordedDeltaSet)

getResolutionType

protected ResolutionType getResolutionType()

Returns:

- resolution type to apply to delta

canExecute

public boolean canExecute()

Specified by:

canExecute in interface org.eclipse.emf.common.command.Command

execute

public void execute()

Resolves a delta with the given resolution, either the delta's default resolution, or the ignore resolution. Collect all related deltas. The related deltas include the newtwork of deltas involved in atomic deltas, as well as all their prerequisites, if given the default resolution, or dependents, if given the ignore resolution. The related deltas also includes any of these delta's conflicting deltas. Separate all the deltas by contributor. Sequence each of them for the given resolution. Record all delta's old resolutions. resolve each delta.

Specified by:

execute in interface org.eclipse.emf.common.command.Command
