Example 26 with KtExpression

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

the class FunctionBodyTranslator method setDefaultValueForArguments.

@NotNull
public static List<JsStatement> setDefaultValueForArguments(@NotNull FunctionDescriptor descriptor, @NotNull TranslationContext functionBodyContext) {
    List<ValueParameterDescriptor> valueParameters = descriptor.getValueParameters();
    List<JsStatement> result = new ArrayList<JsStatement>(valueParameters.size());
    for (ValueParameterDescriptor valueParameter : valueParameters) {
        if (!valueParameter.declaresDefaultValue())
            continue;
        JsNameRef jsNameRef = functionBodyContext.getNameForDescriptor(valueParameter).makeRef();
        KtExpression defaultArgument = getDefaultArgument(valueParameter);
        JsBlock defaultArgBlock = new JsBlock();
        JsExpression defaultValue = Translation.translateAsExpression(defaultArgument, functionBodyContext, defaultArgBlock);
        JsStatement assignStatement = assignment(jsNameRef, defaultValue).makeStmt();
        JsStatement thenStatement = JsAstUtils.mergeStatementInBlockIfNeeded(assignStatement, defaultArgBlock);
        JsBinaryOperation checkArgIsUndefined = equality(jsNameRef, Namer.getUndefinedExpression());
        JsIf jsIf = JsAstUtils.newJsIf(checkArgIsUndefined, thenStatement);
        result.add(jsIf);
    }
    return result;
}

Example 27 with KtExpression

the class CallBasedArgumentGenerator method generateExpression.

@Override
protected void generateExpression(int i, @NotNull ExpressionValueArgument argument) {
    ValueParameterDescriptor parameter = valueParameters.get(i);
    Type type = valueParameterTypes.get(i);
    ValueArgument valueArgument = argument.getValueArgument();
    assert valueArgument != null;
    KtExpression argumentExpression = valueArgument.getArgumentExpression();
    assert argumentExpression != null : valueArgument.asElement().getText();
    callGenerator.genValueAndPut(parameter, argumentExpression, type, i);
}
