◆ JSContextGetGlobalContext()

JSGlobalContextRef JSContextGetGlobalContext ( JSContextRef ctx )

Gets the global context of a JavaScript execution context.

Parameters

ctx	The JSContext whose global context you want to get.

Returns: ctx's global context.

◆ JSContextGetGlobalObject()

JSObjectRef JSContextGetGlobalObject ( JSContextRef ctx )

Gets the global object of a JavaScript execution context.

Parameters

ctx	The JSContext whose global object you want to get.

Returns: ctx's global object.

◆ JSContextGetGroup()

JSContextGroupRef JSContextGetGroup ( JSContextRef ctx )

Gets the context group to which a JavaScript execution context belongs.

Parameters

ctx	The JSContext whose group you want to get.

Returns: ctx's group.

◆ JSContextGroupCreate()

JSContextGroupRef JSContextGroupCreate ( void )

Creates a JavaScript context group.

Note

A JSContextGroup associates JavaScript contexts with one another. Contexts in the same group may share and exchange JavaScript objects. Sharing and/or exchanging JavaScript objects between contexts in different groups will produce undefined behavior. When objects from the same context group are used in multiple threads, explicit synchronization is required.

A JSContextGroup may need to run deferred tasks on a run loop, such as garbage collection or resolving WebAssembly compilations. By default, calling JSContextGroupCreate will use the run loop of the thread it was called on. Currently, there is no API to change a JSContextGroup's run loop once it has been created.

Returns: The created JSContextGroup.

◆ JSContextGroupRelease()

void JSContextGroupRelease ( JSContextGroupRef group )

Releases a JavaScript context group.

Parameters

group The JSContextGroup to release.

◆ JSContextGroupRetain()

JSContextGroupRef JSContextGroupRetain ( JSContextGroupRef group )

Retains a JavaScript context group.

Parameters

group The JSContextGroup to retain.

Returns: A JSContextGroup that is the same as group.

◆ JSGlobalContextCopyName()

JSStringRef JSGlobalContextCopyName ( JSGlobalContextRef ctx )

Gets a copy of the name of a context.

Parameters

ctx	The JSGlobalContext whose name you want to get.

Returns: The name for ctx.

Note: A JSGlobalContext's name is exposed when inspecting the context to make it easier to identify the context you would like to inspect.

◆ JSGlobalContextCreate()

JSGlobalContextRef JSGlobalContextCreate ( JSClassRef globalObjectClass )

Creates a global JavaScript execution context.

Note

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.

Parameters

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

Returns: A JSGlobalContext with a global object of class globalObjectClass.

◆ JSGlobalContextCreateInGroup()

JSGlobalContextRef JSGlobalContextCreateInGroup	(	JSContextGroupRef	group,
		JSClassRef	globalObjectClass )

Creates a global JavaScript execution context in the context group provided.

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

Parameters

globalObjectClass	The class to use when creating the global object. Pass NULL to use the default object class.
group	The context group to use. The created global context retains the group. Pass NULL to create a unique group for the context.

Returns: A JSGlobalContext with a global object of class globalObjectClass and a context group equal to group.

◆ JSGlobalContextIsInspectable()

bool JSGlobalContextIsInspectable ( JSGlobalContextRef ctx )

Gets whether the context is inspectable in Web Inspector.

Parameters

ctx	The JSGlobalContext that you want to change the inspectability of.

Returns: Whether the context is inspectable in Web Inspector.

◆ JSGlobalContextRelease()

void JSGlobalContextRelease ( JSGlobalContextRef ctx )

Releases a global JavaScript execution context.

Parameters

ctx	The JSGlobalContext to release.

◆ JSGlobalContextRetain()

JSGlobalContextRef JSGlobalContextRetain ( JSGlobalContextRef ctx )

Retains a global JavaScript execution context.

Parameters

ctx	The JSGlobalContext to retain.

Returns: A JSGlobalContext that is the same as ctx.

◆ JSGlobalContextSetInspectable()

void JSGlobalContextSetInspectable	(	JSGlobalContextRef	ctx,
		bool	inspectable )

Sets whether the context is inspectable in Web Inspector. Default value is NO.

Parameters

ctx	The JSGlobalContext that you want to change the inspectability of.
inspectable	YES to allow Web Inspector to connect to the context, otherwise NO.

◆ JSGlobalContextSetName()

void JSGlobalContextSetName	(	JSGlobalContextRef	ctx,
		JSStringRef	name )

Sets the name exposed when inspecting a context.

Parameters

ctx	The JSGlobalContext that you want to name.
name	The name to set on the context.
