Function

JSGlobalContextCreate(_:)

Creates a global JavaScript execution context.

Declaration

func JSGlobalContextCreate(_ globalObjectClass: JSClassRef!) -> JSGlobalContextRef!

Parameters

globalObjectClass

The class to use when creating the global object. Pass NULL to use the default object class.

Return Value

A JSGlobalContext with a global object of class globalObjectClass.

Discussion

JSGlobalContextCreate allocates a global object and populates it with all the built-in JavaScript objects, such as Object, Function, String, and Array.

In WebKit version 4.0 and later, the context is created in a unique context group. Therefore, scripts may execute in it concurrently with scripts executing in other contexts. However, you may not use values created in the context in other contexts.
