Public Methods

Method	Description
CanSave ( IWritingSystem ws, string &path ) : bool	Return true if we expect (absent pathological changes while we're not looking) to be able to save changes to this writing system.
CheckForNewerGlobalWritingSystems ( ) : IEnumerable	Gets all newer shared writing systems.
Create ( LanguageSubtag languageSubtag, ScriptSubtag scriptSubtag, RegionSubtag regionSubtag, VariantSubtag variantSubtag ) : IWritingSystem	Creates a new writing system.
Create ( string identifier ) : IWritingSystem	Creates a new writing system.
CreateFrom ( IWritingSystem ws ) : IWritingSystem	Creates a copy of the specified writing system.
Exists ( int handle ) : bool	Determines if a writing system exists with the specified handle.
Exists ( string identifier ) : bool	Determines if a writing system exists with the specified RFC5646 identifier.
Get ( int handle ) : IWritingSystem	Gets the writing system with the specified handle.
Get ( string identifier ) : IWritingSystem	Gets the specified writing system. Throws KeyNotFoundException if it can not be found, there is a TryGet available to avoid this.
GetOrSet ( string identifier, IWritingSystem &ws ) : bool	Gets the specified writing system if it exists, otherwise it creates a writing system using the specified identifier and sets it.
GetStrFromWs ( int handle ) : string	Gets the RFC5646 identifier from the handle.
GetValidLangTagForNewLang ( string langName ) : string	Returns an ISO 639 language tag that is guaranteed to be valid and unique for both the local and the global writing system store. NOTE: This method should only be used for writing systems that are custom (i.e. not defined in the current version of the ethnologue). The returned code will not have the 'x-' prefix denoting a user-defined writing system, but it will check that an existing user-defined writing system does not exist with the returned language tag. This method also does not worry about regions, variants, etc. as it's use is restricted to the language tag for a custom writing system.
GetWritingSystems ( SIL.FieldWorks.Common.COMInterfaces.ArrayPtr rgws, int cws ) : void	Get the list of writing systems currrently installed in the system.
GetWsFromStr ( string identifier ) : int	Gets the HVO from the RFC5646 identifier.
PalasoWritingSystemManager ( ) : System	Initializes a new instance of the PalasoWritingSystemManager class.
PalasoWritingSystemManager ( IFwWritingSystemStore store ) : System	Initializes a new instance of the PalasoWritingSystemManager class.
PalasoWritingSystemManager ( IFwWritingSystemStore localStore, IFwWritingSystemStore globalStore ) : System	Initializes a new instance of the PalasoWritingSystemManager class. localStore and globalStore will be disposed by the PalasoWritingSystemManager!
Replace ( IWritingSystem ws ) : void	Replaces an existing writing system with the specified writing system if they have the same identifier.
Save ( ) : void	Persists all modified writing systems.
Set ( string identifier ) : IWritingSystem	Creates a writing system using the specified identifier and sets it.
Set ( IWritingSystem ws ) : void	Sets the specified writing system.
TryGet ( string identifier, IWritingSystem &ws ) : bool	Gets the specified writing system if it exists.
TryGetOrSet ( string identifier, IWritingSystem &ws ) : bool	Gets the specified writing system if it exists, otherwise it creates a writing system using the specified identifier and sets it.
get_CharPropEngine ( int ws ) : ILgCharacterPropertyEngine	Get the char prop engine for a particular WS
get_Engine ( string bstrIdentifier ) : ILgWritingSystem	Get the actual writing system object for a given ICU Locale string. The current implementation returns any existing writing system for that ICU Locale, or creates one with default settings if one is not already known. (Use `get_EngineOrNull` to avoid automatic creation of a new engine.)
get_EngineOrNull ( int ws ) : ILgWritingSystem	Get the actual writing system object for a given code, or returns NULL if one does not already exist. (Use `get_Engine` if you prefer to have an writing system created automatically if one does not already exist.)
get_Renderer ( int ws, IVwGraphics vg ) : IRenderEngine	Get the renderer for a particular WS
get_RendererFromChrp ( IVwGraphics vg, LgCharRenderProps &chrp ) : IRenderEngine	Get the renderer for a particular Chrp

Protected Methods

Method	Description
UnionSettingsKeyboardsWithLocalStore ( ) : string	Performs the Union of Settings.Default.LocalKeyboards and m_localStore.LocalKeyboardSettings and returns the result as an XML string. Protected for tests.

Private Methods

Method	Description
LangTagInUse ( string identifier ) : bool	Determines whether or not the specified language tag is in use by another writing system in either the local or global writing system store.
RegisterRenderEngine ( IRenderEngine engine ) : void
Set ( string identifier, bool &foundExisting ) : IWritingSystem	Create the writing system. Typically we will create it, but we may have to modify the ID and then find that there is an existing one. Set foundExisting true if so.
