Example 1 with SemanticModificationWrapper

use of org.eclipse.xtext.ui.editor.model.edit.SemanticModificationWrapper in project xtext-xtend by eclipse.

the class CreateMemberQuickfixes method newLocalVariableQuickfix.

protected void newLocalVariableQuickfix(final String variableName, XAbstractFeatureCall call, Issue issue, IssueResolutionAcceptor issueResolutionAcceptor) {
    LightweightTypeReference variableType = getNewMemberType(call);
    final StringBuilderBasedAppendable localVarDescriptionBuilder = new StringBuilderBasedAppendable();
    localVarDescriptionBuilder.append("...").newLine();
    final String defaultValueLiteral = getDefaultValueLiteral(variableType);
    localVarDescriptionBuilder.append("val ").append(variableName).append(" = ").append(defaultValueLiteral);
    localVarDescriptionBuilder.newLine().append("...");
    issueResolutionAcceptor.accept(issue, "Create local variable '" + variableName + "'", localVarDescriptionBuilder.toString(), "fix_local_var.png", new SemanticModificationWrapper(issue.getUriToProblem(), new ISemanticModification() {

        @Override
        public void apply(/* @Nullable */
        final EObject element, /* @Nullable */
        final IModificationContext context) throws Exception {
            if (element != null) {
                XtendMember xtendMember = EcoreUtil2.getContainerOfType(element, XtendMember.class);
                if (xtendMember != null) {
                    int offset = getFirstOffsetOfKeyword(xtendMember, "{");
                    IXtextDocument xtextDocument = context.getXtextDocument();
                    if (offset != -1 && xtextDocument != null) {
