C# 클래스 SIL.FieldWorks.FDO.Infrastructure.FdoMetaDataCacheDecoratorBase

Implementation of the IFwMetaDataCacheManaged interface which works with a stateful FDO system for most data issues. For cases where there is a need to store 'fake' data (i.e., not properties of CmObjects), clients should subclass this class and override the relevant methods and read/write that fake meta data in their own internal caches. They should pass the request through to the FdoMetaDataCache (IFwMetaDataCacheManaged) for regular metadata access.

AddVirtualProp ( string bstrClass, string bstrField, int luFlid, int type ) : void	A virtual property. The type can be one of the original types, or any other made up type. This method must be overridden by subclasses, so they can add non-model properties.
ClassExists ( string className ) : bool	Pass it on by default.
FieldExists ( int flid ) : bool	Return true if the specified field exists.
FieldExists ( int classId, string fieldName, bool includeBaseClasses ) : bool	Pass it on by default.
FieldExists ( string className, string fieldName, bool includeBaseClasses ) : bool	Pass it on by default.
GetAbstract ( int luClid ) : bool	Indicates whether a class is abstract or concrete.
GetAllSubclasses ( int luClid, int cluMax, int &_cluOut, SIL.FieldWorks.Common.COMInterfaces.ArrayPtr _rgluSubclasses ) : void	Gets all subclasses of the given class, including itself (which is always the first result in the list, so it can easily be skipped if desired). The list is therefore a complete list of the classes which are valid to store in a property whose signature is the class identified by luClid.
GetBaseClsId ( int luClid ) : int	Gets the base class id for a given class.
GetBaseClsName ( int luClid ) : string	Gets the name of the base class for a given class.
GetClassId ( string bstrClassName ) : int	:>:> Reverse access methods :> Get the ID of the class having the specified name. Returns 0 if not found.
GetClassIds ( int cclid, SIL.FieldWorks.Common.COMInterfaces.ArrayPtr rgclid ) : void	Gets the list of class identification numbers (in no particular order). If the array provided is too small, only an arbitrary subset of cclid values is returned. If the array provided is too large, the excess entries are set to zero.
GetClassName ( int luClid ) : string	Gets the name of the class.
GetDirectSubclasses ( int luClid, int cluMax, int &_cluOut, SIL.FieldWorks.Common.COMInterfaces.ArrayPtr _rgluSubclasses ) : void	Gets the direct subclasses of the given class (not including itself).
GetDstClsId ( int luFlid ) : int	Gets the "Id" of the destination class that corresponds to this field. This is the "Id" of the class that is either owned or referred to by another class.
GetDstClsName ( int luFlid ) : string	Gets the name of the destination class that corresponds to this field. This is the name of the class that is either owned or referred to by another class.
GetFieldHelp ( int luFlid ) : string	Gets the help string of a field.
GetFieldId ( string bstrClassName, string bstrFieldName, bool fIncludeBaseClasses ) : int	Gets the field ID given the class and field names. Returns 0 if not found. Searches superclasses as well as actual class given.

GetFieldIds ( int cflid, SIL.FieldWorks.Common.COMInterfaces.ArrayPtr rgflid ) : void	Gets the list of field identification numbers (in no particular order). If the array provided is too small, only an arbitrary set of cflid values is returned. If the array provided is too large, the excess entries are set to zero.

GetFieldListRoot ( int luFlid ) : System.Guid	Gets the listRoot of the field.
GetFieldName ( int luFlid ) : string	Gets the name of a field.
GetFieldNameOrNull ( int luFlid ) : string	Gets the name of a field.
GetFieldType ( int luFlid ) : int	Gets the type of the field. This value indicates if the field is a primitive data type or a MultiStr/MultiTxt value or describes the relationship between two classes (i.e. owning/reference and atomic/collection/sequence). These numeric values are defined in the ~FWROOT\src\cellar\lib\CmTypes.h file.
GetFieldWs ( int luFlid ) : int	Gets the Ws of the field.
GetFieldXml ( int luFlid ) : string	Gets the Xml UI of a field.
GetFields ( int luClid, bool fIncludeSuperclasses, int grfcpt, int cflidMax, SIL.FieldWorks.Common.COMInterfaces.ArrayPtr _rgflid ) : int	Gets a list of the fields for the specified class. Gets all fields whose types match the specified argument, which should be a combination of the fcpt values defined in CmTypes.h, e.g., to get all owning properties pass kfcptOwningCollection \| kfcptOwningAtom \| kfcptOwningSequence. Returns E_FAIL if the array is too small. cflidMax 0 may be passed to obtain the required size. Fields of superclasses are also returned, if the relevant flag is true. [Note: The special CmObject fields are not returned, for now, but the plan to include them before too long.]
GetIncomingFields ( int clid, int fieldTypes ) : IEnumerable	Pass it on. Only real fields are interesting here.
GetOwnClsId ( int luFlid ) : int	Gets the "Id" value of the class that contains this field.
GetOwnClsName ( int luFlid ) : string	Gets the name of the class that contains this field.
InitXml ( string bstrPathname, bool fClearPrevCache ) : void	Alternative way to initialize, passing an XML file (like Ling.cm). <class num="int" id="className" base="baseClassName" abstract="true"> <props> <basic num="int" id="FieldName" sig="Boolean/Integer/Time/String/MultiString/MultiUnicode" /> <rel/owning num="int" id="FieldName" card="atomic/seq/col" sig="classname"/> currently doesn't initialize some less essential stuff like help strings and labels. Set fClearPrevCache to false to read in multiple XML files. Enhance JohnT: support attributes to handle these.

FdoMetaDataCacheDecoratorBase ( IFwMetaDataCacheManaged metaDataCache ) : System	Constructor. The hvo values are true 'handles' in that they are valid for one session, but may not be the same integer for another session for the 'same' object. Therefore, one should not use them for multi-session identity. CmObject identity can only be guaranteed by using their Guids (or using '==' in code).
