Field Detail

<static> Obj.getPrototype

Returns the prototype of an object, or null if the function fails to do so.

Deprecated:
use myObj.prototype instead (plus clever checks before)

<static> {Boolean} Obj.XW_instanceof

Cross Window instanceof

Deprecated:
use instanceof instead

Method Detail

<static> {Object} Obj.descend(protototypeParent, childProperties)

Creates a new instance inheriting from a parent "class". That class is then extended with child properties.

Parameters:
{Object} protototypeParent: The parent "class" prototype
{Object} childProperties: The properties extending the new object

Returns:: {Object} the new object

<static> Obj.extend(parentObject)

Clones and extend the object (first parameters) with other objects (following parameters).

var parentObj = {foo: "foo" };
var newObj = Obj.extend(parentObj, {bar: "bar"}); // => {foo: "foo", bar: "bar"}

Parameters:
{Object} parentObject: The object to clone and extend
{Object} ...extensions: the extensions

<static> {Number} Obj.getRandomInt(min, max)

Returns a random integer between min and max

Parameters:
{Number} min: The minimum
{Number} max: The maximum

Returns:: {Number} the random number

<static> {Number} Obj.getUniqueId()

Returns a unique ID (random integer between 0 and 65536)

Returns:: {Number} the random number

<static> Obj.hasProperties(ob, nonEnumProps, ownPropsOnly)

Returns true if the passed object has any properties, otherwise returns false.

Parameters:
{Object} ob: Inspected object
{Object} nonEnumProps: If set to true, check also non-enumerable properties (optional)
{Object} ownPropsOnly: If set to true, only check own properties not inherited (optional)

<static> {boolean} Obj.isNonNativeGetter(obj, propName)

Tells if the given property of the provided object is a non-native getter or not. This method depends on PropertyPanel.jsm module available in Firefox 5+ isNonNativeGetter has been introduced in Firefox 7 The method has been moved to WebConsoleUtils.jsm in Fx 18

Parameters:
{object} obj: The object that contains the property.
{string} propName: The property you want to check if it is a getter or not.

Returns:: {boolean} True if the given property is a getter, false otherwise.
