class Value ValueGidBuilder ValueGidBuilderImpl

Types 3

classValue : gobject.object.ObjectWrap

JSCValue represents a reference to a value in a #JSCContext. The JSCValue protects the referenced value from being garbage collected.

Methods
GType _getGType()
GType _gType() @property
Value self()Returns `this`, for use in `with` statements.
