A Simple Key For double record frame Unveiled

; If an implementation makes an attempt to have or set the value of an attribute on a user object (such as, every time a callback object has become provided into the implementation), Which try brings about an exception being thrown, then, Except in any other case specified, that exception might be propagated on the person code that caused the implementation to accessibility the attribute.

The inherited interfaces of the interface with an iterable declaration need to not even have an iterable declaration.

; In an ECMAScript implementation of your interface, the username attribute will be uncovered for a non-configurable assets on the item alone:

should be a sequence kind, a nullable style whose interior sort is actually a sequence kind or simply a union style or nullable union form

This segment defines numerous extended attributes whose existence influences just the ECMAScript binding.

In any other case: when there is an entry in S which has one among the next kinds at situation i of its variety list,

interface Transaction readonly attribute DOMString from; readonly attribute DOMString to; readonly attribute double volume; readonly attribute DOMString description; readonly attribute unsigned lengthy range; TransactionJSON toJSON();

be utilised on anything aside from an everyday operation for which a corresponding default Procedure is outlined.

The [LegacyNamespace] prolonged attribute is surely an unwanted aspect. It exists only to ensure that legacy World-wide-web platform check out here attributes could be specified. It shouldn't be Utilized in specifications unless required to specify the habits of legacy APIs, or for regularity with these APIs. As a substitute, interface names might be shaped with a naming convention of beginning with a specific prefix for a set of interfaces, as Section of the identifier, as opposed to utilizing a namespace.

The algorithm to compute a powerful overload set operates on amongst the subsequent six sorts of IDL constructs, and stated with them down below are

The problem is exacerbated when among the overloads features a return type of void, since union forms cannot even comprise void for a member variety. In that situation, a return style

; assuming Node and Celebration are two other interfaces of which no item can apply equally, the efficient overload set for normal operations with identifier file and argument rely four is:

Unless of course in redirected here any other case specified, Every ECMAScript global natural environment exposes all interfaces which the implementation supports. If a supplied ECMAScript world wide setting would not

For just about any sort, the extended characteristics connected with it need to only include extended characteristics which might be applicable to styles.
