示例1: visitCall

import com.google.javascript.rhino.jstype.JSType; //导入方法依赖的package包/类
/**
 * Visits a CALL node.
 *
 * @param t The node traversal object that supplies context, such as the
 * scope chain to use in name lookups as well as error reporting.
 * @param n The node being visited.
 */
private void visitCall(NodeTraversal t, Node n) {
  Node child = n.getFirstChild();
  JSType childType = getJSType(child).restrictByNotNullOrUndefined();

  if (!childType.canBeCalled()) {
    t.report(n, NOT_CALLABLE, childType.toString());
    ensureTyped(t, n);
    return;
  }

  // A couple of types can be called as if they were functions.
  // If it is a function type, then validate parameters.
  if (childType instanceof FunctionType) {
    FunctionType functionType = (FunctionType) childType;

    // Non-native constructors should never be called directly.
    if (functionType.isConstructor() &&
        !functionType.isNativeObjectType()) {
      t.report(n, CONSTRUCTOR_NOT_CALLABLE, childType.toString());
    }

    visitParameterList(t, n, functionType);
    ensureTyped(t, n, functionType.getReturnType());
  } else {
    ensureTyped(t, n);
  }

  // TODO: Add something to check for calls of RegExp objects, which is not
  // supported by IE.  Either say something about the return type or warn
  // about the non-portability of the call or both.
