Example 1 with KtIfExpression

use of org.jetbrains.kotlin.psi.KtIfExpression in project kotlin by JetBrains.

the class KotlinIfSurrounderBase method surroundStatements.

@Nullable
@Override
protected TextRange surroundStatements(Project project, Editor editor, PsiElement container, PsiElement[] statements) {
    statements = MoveDeclarationsOutHelper.move(container, statements, isGenerateDefaultInitializers());

        return null;
    }
    KtIfExpression ifExpression = (KtIfExpression) KtPsiFactoryKt.KtPsiFactory(project).createExpression(getCodeTemplate());
    ifExpression = (KtIfExpression) container.addAfter(ifExpression, statements[statements.length - 1]);
    // TODO move a comment for first statement
    KtBlockExpression thenBranch = (KtBlockExpression) ifExpression.getThen();
    assert thenBranch != null : "Then branch should exist for created if expression: " + ifExpression.getText();
    // Add statements in then branch of created if
    KotlinSurrounderUtils.addStatementsInBlock(thenBranch, statements);
    // Delete statements from original code
    container.deleteChildRange(statements[0], statements[statements.length - 1]);
    ifExpression = CodeInsightUtilBase.forcePsiPostprocessAndRestoreElement(ifExpression);
    KtExpression condition = ifExpression.getCondition();
    assert condition != null : "Condition should exists for created if expression: " + ifExpression.getText();
    // Delete condition from created if
    TextRange range = condition.getTextRange();
    TextRange textRange = new TextRange(range.getStartOffset(), range.getStartOffset());
