Example 1 with Parameters

use of net.jangaroo.jooc.ast.Parameters in project jangaroo-tools by CoreMedia.

the class JsCodeGenerator method getParameterInitializerCodeGenerator.

public CodeGenerator getParameterInitializerCodeGenerator(final Parameters params) {
    return new CodeGenerator() {

        @Override
        public void generate(JsWriter out, boolean first) throws IOException {
            // collect the ... (rest) parameter and all optional parameters with their position index:
            int restParamIndex = -1;
            Parameter restParam = null;
            Map<Integer, Parameter> paramByIndex = new HashMap<Integer, Parameter>();
            Parameters parameters = params;
            for (int paramIndex = 0; parameters != null; parameters = parameters.getTail()) {
                Parameter param = parameters.getHead();
                if (param.isRest()) {
                    restParamIndex = paramIndex;
                    restParam = param;
                    break;
                }
                if (param.hasInitializer()) {
                    paramByIndex.put(paramIndex, param);
                }
                ++paramIndex;
            }
            generateParameterInitializers(out, paramByIndex);
            if (restParam != null) {
                generateRestParamCode(restParam, restParamIndex);
            }
        }
    };
}

Example 2 with Parameters

use of net.jangaroo.jooc.ast.Parameters in project jangaroo-tools by CoreMedia.

the class JsCodeGenerator method generateFunTailCode.

public void generateFunTailCode(FunctionExpr functionExpr) throws IOException {
    Parameters params = functionExpr.getParams();
    if (functionExpr.hasBody()) {
        if (functionExpr.isArgumentsUsedAsArray()) {
            functionExpr.getBody().addBlockStartCodeGenerator(ARGUMENT_TO_ARRAY_CODE_GENERATOR);
        }
        if (params != null) {
            // inject into body for generating initializers later:
            functionExpr.getBody().addBlockStartCodeGenerator(getParameterInitializerCodeGenerator(params));
        }
    }
    generateSignatureJsCode(functionExpr);
    if (functionExpr.hasBody()) {
        functionExpr.getBody().visit(this);
    }
}
