CefV8Value Class

Class representing a V8 value handle. V8 handles can only be accessed from the thread on which they are created. Valid threads for creating a V8 handle include the render process main thread (TID_RENDERER) and WebWorker threads. A task runner for posting tasks on the associated thread can be retrieved via the CefV8Context::GetTaskRunner() method.

public sealed class CefV8Value : IDisposable

The CefV8Value type exposes the following members.

Properties

	Name	Description
	HasException	Returns true if the last method call resulted in an exception. This attribute exists only in the scope of the current CEF value object.
	IsArray	True if the value type is array.
	IsBool	True if the value type is bool.
	IsDate	True if the value type is Date.
	IsDouble	True if the value type is double.
	IsFunction	True if the value type is function.
	IsInt	True if the value type is int.
	IsNull	True if the value type is null.
	IsObject	True if the value type is object.
	IsString	True if the value type is string.
	IsUInt	True if the value type is unsigned int.
	IsUndefined	True if the value type is undefined.
	IsUserCreated	OBJECT METHODS - These methods are only available on objects. Arrays and functions are also objects. String- and integer-based keys can be used interchangably with the framework converting between them as necessary. Returns true if this is a user created object.
	IsValid	Returns true if the underlying handle is valid and it can be accessed on the current thread. Do not call any other methods if this method returns false.

Methods

	Name	Description
	AdjustExternallyAllocatedMemory	Adjusts the amount of registered external memory for the object. Used to give V8 an indication of the amount of externally allocated memory that is kept alive by JavaScript objects. V8 uses this information to decide when to perform global garbage collection. Each CefV8Value tracks the amount of external memory associated with it and automatically decreases the global total by the appropriate amount on its destruction. \|change_in_bytes\| specifies the number of bytes to adjust by. This method returns the number of bytes associated with the object after the adjustment. This method can only be called on user created objects.
	ClearException	Clears the last exception and returns true on success.
	CreateArray	Create a new CefV8Value object of type array with the specified \|length\|. If \|length\| is negative the returned array will have length 0. This method should only be called from within the scope of a CefRenderProcessHandler, CefV8Handler or CefV8Accessor callback, or in combination with calling Enter() and Exit() on a stored CefV8Context reference.
	CreateBool	Create a new CefV8Value object of type bool.
	CreateDate	Create a new CefV8Value object of type Date. This method should only be called from within the scope of a CefRenderProcessHandler, CefV8Handler or CefV8Accessor callback, or in combination with calling Enter() and Exit() on a stored CefV8Context reference.
	CreateDouble	Create a new CefV8Value object of type double.
	CreateFunction	Create a new CefV8Value object of type function. This method should only be called from within the scope of a CefRenderProcessHandler, CefV8Handler or CefV8Accessor callback, or in combination with calling Enter() and Exit() on a stored CefV8Context reference.
	CreateInt	Create a new CefV8Value object of type int.
	CreateNull	Create a new CefV8Value object of type null.
	CreateObject	Create a new CefV8Value object of type object with optional accessor. This method should only be called from within the scope of a CefRenderProcessHandler, CefV8Handler or CefV8Accessor callback, or in combination with calling Enter() and Exit() on a stored CefV8Context reference.
	CreateString	Create a new CefV8Value object of type string.
	CreateUInt	Create a new CefV8Value object of type unsigned int.
	CreateUndefined	Create a new CefV8Value object of type undefined.
	DeleteValue(Int32)	Deletes the value with the specified identifier and returns true on success. Returns false if this method is called incorrectly, deletion fails or an exception is thrown. For read-only and don't-delete values this method will return true even though deletion failed.
	DeleteValue(String)	Deletes the value with the specified identifier and returns true on success. Returns false if this method is called incorrectly or an exception is thrown. For read-only and don't-delete values this method will return true even though deletion failed.
	Dispose	Releases all resources used by the CefV8Value
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	ExecuteFunction	Execute the function using the current V8 context. This method should only be called from within the scope of a CefV8Handler or CefV8Accessor callback, or in combination with calling Enter() and Exit() on a stored CefV8Context reference. \|object\| is the receiver ('this' object) of the function. If \|object\| is empty the current context's global object will be used. \|arguments\| is the list of arguments that will be passed to the function. Returns the function return value on success. Returns NULL if this method is called incorrectly or an exception is thrown.
	ExecuteFunctionWithContext	Execute the function using the specified V8 context. \|object\| is the receiver ('this' object) of the function. If \|object\| is empty the specified context's global object will be used. \|arguments\| is the list of arguments that will be passed to the function. Returns the function return value on success. Returns NULL if this method is called incorrectly or an exception is thrown.
	Finalize	(Overrides ObjectFinalize)
	GetArrayLength	ARRAY METHODS - These methods are only available on arrays. Returns the number of elements in the array.
	GetBoolValue	Return a bool value. The underlying data will be converted to if necessary.
	GetDateValue	Return a Date value. The underlying data will be converted to if necessary.
	GetDoubleValue	Return a double value. The underlying data will be converted to if necessary.
	GetException	Returns the exception resulting from the last method call. This attribute exists only in the scope of the current CEF value object.
	GetExternallyAllocatedMemory	Returns the amount of externally allocated memory registered for the object.
	GetFunctionHandler	Returns the function handler or NULL if not a CEF-created function.
	GetFunctionName	FUNCTION METHODS - These methods are only available on functions. Returns the function name.
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetIntValue	Return an int value. The underlying data will be converted to if necessary.
	GetKeys	Read the keys for the object's values into the specified vector. Integer- based keys will also be returned as strings.
	GetStringValue	Return a string value. The underlying data will be converted to if necessary.
	GetType	Gets the Type of the current instance. (Inherited from Object)
	GetUIntValue	Return an unisgned int value. The underlying data will be converted to if necessary.
	GetUserData	Returns the user data, if any, assigned to this object.
	GetValue(Int32)	Returns the value with the specified identifier on success. Returns NULL if this method is called incorrectly or an exception is thrown.
	GetValue(String)	Returns the value with the specified identifier on success. Returns NULL if this method is called incorrectly or an exception is thrown.
	HasValue(Int32)	Returns true if the object has a value with the specified identifier.
	HasValue(String)	Returns true if the object has a value with the specified identifier.
	IsSame	Returns true if this object is pointing to the same handle as \|that\| object.
	SetRethrowExceptions	Set whether this object will re-throw future exceptions. By default exceptions are not re-thrown. If a exception is re-thrown the current context should not be accessed again until after the exception has been caught and not re-thrown. Returns true on success. This attribute exists only in the scope of the current CEF value object.
	SetUserData	Sets the user data for this object and returns true on success. Returns false if this method is called incorrectly. This method can only be called on user created objects.
	SetValue(Int32, CefV8Value)	Associates a value with the specified identifier and returns true on success. Returns false if this method is called incorrectly or an exception is thrown. For read-only values this method will return true even though assignment failed.
	SetValue(String, CefV8AccessControl, CefV8PropertyAttribute)	Registers an identifier and returns true on success. Access to the identifier will be forwarded to the CefV8Accessor instance passed to CefV8Value::CreateObject(). Returns false if this method is called incorrectly or an exception is thrown. For read-only values this method will return true even though assignment failed.
	SetValue(String, CefV8Value, CefV8PropertyAttribute)	Associates a value with the specified identifier and returns true on success. Returns false if this method is called incorrectly or an exception is thrown. For read-only values this method will return true even though assignment failed.
	ToString	Returns a string that represents the current object. (Inherited from Object)
	TryGetKeys	Read the keys for the object's values into the specified vector. Integer- based keys will also be returned as strings.
