Метод	Описание
DeclareVariable ( string name, Jurassic.Compiler.Expression valueAtTopOfScope = null, bool writable = true, bool deletable = false ) : DeclaredVariable	Declares a variable or function in this scope. This will be initialized with the value of the given expression.
GenerateDeclarations ( ILGenerator generator, OptimizationInfo optimizationInfo ) : void	Generates code that initializes the variable and function declarations.
GenerateScopeCreation ( ILGenerator generator, OptimizationInfo optimizationInfo ) : void	Generates code that creates a new scope.
GenerateScopeDestruction ( ILGenerator generator, OptimizationInfo optimizationInfo ) : void	Generates code that restores the parent scope as the active scope.
GetDeclaredVariable ( string variableName ) : DeclaredVariable	Gets the index of the given variable.
HasDeclaredVariable ( string name ) : bool	Returns `true` if the given variable has been declared in this scope.
RemovedDeclaredVariable ( string name ) : void	Removes a declared variable from the scope.
