C# Class Microsoft.Scripting.ScopeStorage

Provides optimized and cacheable support for scope storage. This is the default object used for storing values in a scope.

The implementation uses a case-insensitive dictionary which holds onto ScopeVariableIgnoreCase objects. The SVIC's hold onto ScopeVariable objects for each possible casing.

Public Methods

Method	Description
DeleteValue ( string name, bool ignoreCase ) : bool	Deletes the named value from the scope optionally ignoring the case.
GetItems ( ) : dynamic>>.IList	Returns all of the member names and their associated values from the scope. The list contains all available casings.
GetMemberNames ( ) : IList	Returns all of the member names which currently have values in the scope. The list contains all available casings.
GetMetaObject ( Expression parameter ) : DynamicMetaObject
GetScopeVariable ( string name, bool ignoreCase ) : IScopeVariable	Gets the IScopeVariable for the scope optionally ignoring case. The IScopeVariable can be held onto and get/set/deleted without performing a dictionary lookup on subsequent accesses.
GetScopeVariable ( string name ) : ScopeVariable	Gets the ScopeVariable for the scope in a case-sensitive manner. The ScopeVariable can be held onto and get/set/deleted without performing a dictionary lookup on subsequent accesses.
GetScopeVariableIgnoreCase ( string name ) : ScopeVariableIgnoreCase	Gets the ScopeVariableIgnoreCase for the scope in a case-insensitive manner. The ScopeVariable can be held onto and get/set/deleted without performing a dictionary lookup on subsequent accesses.
GetValue ( string name, bool ignoreCase ) : Object	Gets the named value from the scope optionally ignoring case. If the named value is not present an InvalidOperationException is raised.
HasValue ( string name, bool ignoreCase ) : bool	Checks if the named value is present in the scope optionally ignoring the case.
SetValue ( string name, bool ignoreCase, object value ) : void	Sets the named value in the scope optionally ignoring the case.
TryGetValue ( string name, bool ignoreCase, Object &value ) : bool	Attempts to get the named value from the scope optionally ignoring the case. Returns true if the value is present, false if it is not.
this ( string index ) : Object	Provides convenient case-sensitive value access.
