Examples with ChangeConverter org.eclipse.xtext.ui.refactoring2.ChangeConverter used on opensource projects

Example 1 with ChangeConverter

use of org.eclipse.xtext.ui.refactoring2.ChangeConverter in project xtext-eclipse by eclipse.

the class ResourceRelocationProcessor method createChange.

public Change createChange(String name, ResourceRelocationContext.ChangeType type, IProgressMonitor pm) throws CoreException, OperationCanceledException {
    if (uriChanges.isEmpty()) {
        return null;
    }
    SubMonitor subMonitor = SubMonitor.convert(pm);
    // Declaring the task and its effort in 'SubMonitor.convert(...)' doesn't yield the expected UI updates
    // so let's do it separately; the total effort of '5' is chosen for weighting the subsequent efforts
    subMonitor.beginTask("Preparing the refactoring...", 5);
    IChangeSerializer changeSerializer = changeSerializerProvider.get();
    ResourceSet resourceSet = resourceSetProvider.get(project);
    ResourceRelocationContext context = new ResourceRelocationContext(type, uriChanges, issues, changeSerializer, resourceSet);
    boolean persistedIndexUsageRequested = isPersistedIndexUsageRequested(context);
    // TODO check preconditions like all editors being saved if 'persistedIndexUsageRequested' == true
    initializeResourceSet(persistedIndexUsageRequested, context);
    executeParticipants(context, subMonitor.split(1));
    ChangeConverter changeConverter = // 
    changeConverterFactory.create(// 
    name, (it) -> {
        return (!(it instanceof MoveResourceChange || it instanceof RenameResourceChange) || !excludedResources.contains(it.getModifiedElement()));
    }, issues);
    // remaining effort is assigned to 'changeSerializer's work
    SubMonitor modificationApplicationMonitor = subMonitor.split(4);
    changeSerializer.setProgressMonitor(modificationApplicationMonitor);
    changeSerializer.applyModifications(changeConverter);
    modificationApplicationMonitor.done();
    return changeConverter.getChange();
}

Example 2 with ChangeConverter

use of org.eclipse.xtext.ui.refactoring2.ChangeConverter in project xtext-eclipse by eclipse.

the class RenameElementProcessor2 method checkFinalConditions.

    RenameChange renameChange = new RenameChange(newName, renameElementContext.getTargetElementURI());
    RenameContext renameContext = new RenameContext(Arrays.asList(renameChange), resourceSet, changeSerializer, status);

    ChangeConverter changeConverter = changeConverterFactory.create(name, null, status);
