class CefV8Context

extends CefBase

Class that encapsulates a V8 context handle. The methods of this class may only be called on the UI thread.

Enter

public virtual bool Enter()= 0;

Enter this context. A context must be explicitly entered before creating a V8 Object, Array, Function or Date asynchronously. Exit() must be called the same number of times as Enter() before releasing this context. V8 objects belong to the context in which they are created. Returns true if the scope was entered successfully.

Eval

public virtual bool Eval( const CefString& code, CefRefPtr< CefV8Value >& retval, CefRefPtr< CefV8Exception >& exception )= 0;

Evaluates the specified JavaScript code using this context's global object. On success |retval| will be set to the return value, if any, and the function will return true. On failure |exception| will be set to the exception, if any, and the function will return false.

Exit

public virtual bool Exit()= 0;

Exit this context. Call this method only after calling Enter(). Returns true if the scope was exited successfully.

GetBrowser

public virtual CefRefPtr< CefBrowser > GetBrowser()= 0;

Returns the browser for this context.

GetCurrentContext

public static CefRefPtr< CefV8Context > GetCurrentContext();

Returns the current (top) context object in the V8 context stack.

GetEnteredContext

public static CefRefPtr< CefV8Context > GetEnteredContext();

Returns the entered (bottom) context object in the V8 context stack.

GetFrame

public virtual CefRefPtr< CefFrame > GetFrame()= 0;

Returns the frame for this context.

GetGlobal

public virtual CefRefPtr< CefV8Value > GetGlobal()= 0;

Returns the global object for this context. The context must be entered before calling this method.

InContext

public static bool InContext();

Returns true if V8 is currently inside a context.

IsSame

public virtual bool IsSame( CefRefPtr< CefV8Context > that )= 0;

Returns true if this object is pointing to the same handle as |that| object.

IsValid

public virtual bool IsValid()= 0;

Returns true if this object is valid. Do not call any other methods if this method returns false.
