Méthodes publiques

Méthode Description
Dispose ( ) : void

Clean up all engines
DisposeEngineForCurrentThread ( ) : void

Disposes the JavaScript engine for the current thread.
EnsureValidState ( ) : void

Ensures that this object has not been disposed, and that no error was thrown while loading the scripts.
GetEngine ( ) : IJsEngine

Gets a JavaScript engine from the pool.
GetEngineForCurrentThread ( ) : IJsEngine

Gets the JavaScript engine for the current thread. It is recommended to use GetEngine instead, which will pool/reuse engines.
JavaScriptEngineFactory ( JsEngineSwitcher jsEngineSwitcher, IReactSiteConfiguration config, IFileSystem fileSystem ) : System

Initializes a new instance of the JavaScriptEngineFactory class.
ReturnEngineToPool ( IJsEngine engine ) : void

Returns an engine to the pool so it can be reused

Méthodes protégées

Méthode Description
CreatePool ( ) : IJsPool

Creates a new JavaScript engine pool.
InitialiseEngine ( IJsEngine engine ) : void

Loads standard React and Babel scripts into the engine.

Private Methods

Méthode Description
EngineIsUsable ( IJsEngine engine, bool allowMsie ) : bool

Performs a sanity check to ensure the specified engine type is usable.
EnsureJsEnginesRegistered ( JsEngineSwitcher jsEngineSwitcher, bool allowMsie ) : void

Ensures that some engines have been registered with JavaScriptEngineSwitcher. IF not, registers some default engines.
EnsureReactLoaded ( IJsEngine engine ) : void

Ensures that React has been correctly loaded into the specified engine.
GetFactory ( JsEngineSwitcher jsEngineSwitcher, bool allowMsie ) : Func

Gets a factory for the most appropriate JavaScript engine for the current environment. The first functioning JavaScript engine with the lowest priority will be used.
LoadUserScripts ( IJsEngine engine ) : void

Loads any user-provided scripts. Only scripts that don't need JSX transformation can run immediately here. JSX files are loaded in ReactEnvironment.
