Public Methods

Method	Description
BuildIndexAsync ( IPackageIndex packageIndex = null ) : System.Threading.Tasks.Task
GetFunctionInfo ( string functionName, string packageName, string>.Action infoReadyCallback = null, object parameter = null ) : IFunctionInfo	Retrieves function information by name. If information is not available, starts asynchronous retrieval of the function info from R and when the data becomes available invokes specified callback passing the parameter. This is used for async intellisense or function signature/parameter help.
GetFunctionInfoAsync ( string functionName, string packageName = null ) : Task
RegisterPackageFunctions ( IPackageInfo package ) : void

Private Methods

Method	Description
FunctionIndex ( ICoreShell coreShell, IFunctionRdDataProvider rdDataProfider, IIntellisenseRSession host ) : System
GetFunctionInfoFromEngineAsync ( string functionName, string packageName, string>.Action infoReadyCallback = null, object parameter = null ) : Task	Fetches help on the function from R asynchronously. When function data is obtained, parsed and the function index is updated, method invokes infoReadyCallback callback passing the specified parameter. Callback method can now fetch function information from the index.
GetFunctionInfosFromRd ( string rdData ) : IReadOnlyList
GetQualifiedName ( string functionName, string packageName ) : string
RegisterFunction ( string functionName, string packageName ) : void
TryGetCachedFunctionInfo ( string functionName, string &packageName ) : IFunctionInfo	Attempts to retrieve function information from cache is a simple manner. Specifically, when function name is unique (then package name is irrelevant) or the package name is known.
UpdateIndex ( string functionName, string packageName, string rdData ) : void
