1. TUF23: TRIM User Forum 2010 Changing the Economics of IM Rory Kleeman Software Architect, HP Information Management

2. TRIM User Forum 2010 TRIM SDK.NET A new development toolkit

3. TRIM User Forum 2010 Why TRIM SDK.NET? –Support.NET developers with a more natural.NET interface –Improve memory model for.NET development environment ReleaseCOMObject difficult to use –More object-oriented hierarchy –Tidy up a long-standing COM interface

4. TRIM User Forum 2010 Main Object Hierarchy TrimObject TrimPropertySet TrimMainObject TrimChildObject TrimObject Record Location and more...

5. TRIM User Forum 2010 TrimPropertySet –A set of property values, each identified by a PropertyIds value –Properties ErrorMessage Error (derives from TrimException : ApplicationException) Caption Database Icon (new TrimIcon class) IsModified –Methods GetProperty (PropertyIds) returns Object GetPropertyIcon (PropertyIds) returns TrimIcon SetProperty(PropertyIds, Object) GetPropertyAsString(PropertyIds, DisplayType) IsMandatory(PropertyIds) VerifyProperty(PropertyIds) CanModifyProperty(PropertyIds)

6. TRIM User Forum 2010 TrimObject –Derives from TrimPropertySet, identified by a BaseObjectTypes value –Properties TrimType (each TrimObject is of type BaseObjectTypes) Uri (64-bit unique identifier) NameString (eg, Record.RecordNumber ) NameStringExtra (eh, Record.Title) IsReadOnly –Methods IsMandatory(FieldDefinition) IsValidFor(Purpose, …) –Interfaces, used for special capabilities (see Get…Interface methods) ITrimNotes ITrimUserFields ITrimAccessControl ITrimActiveDates ITrimDocument

7. TRIM User Forum 2010 TrimMainObject –Derives from TrimObject, designed to be “persisted” –Properties Verified LastUpdatedOn (used for update synchronisation) Uri (64-bit unique identifier) NameString (eg, Record.RecordNumber ) NameStringExtra (eh, Record.Title) IsReadOnly –Methods Verify(…) Save(), to persist any changes Delete(), is permanent MakeReference(RefFileName) GetChildObjectList(BaseObjectTypes childType) –Interfaces, used for special capabilities (see Get…Interface methods) ITrimSecurity ITrimAccessControlDefault ITrimLabels

8. TRIM User Forum 2010 TrimChildObject –Derives from TrimObject, contained within a TrimChildObjectList –Properties ParentList, the parent TrimChildObjectList –Methods Delete() −removes from parent, −not permanent until parent object is saved −care required when calling in a loop

9. TRIM User Forum 2010 TrimChildObjectList –Derives from IEnumerable belongs to a TrimMainObject implements a concept of an array of propertySets –Properties ErrorMessage, Error, Database ParentObject ParentList, the parent TrimChildObjectList TrimType Count Item[index] –Methods GetEnumerator() FindChildByUri(Uri) –Supports foreach ( TrimChildObject obj in myChildList )

10. TRIM User Forum 2010 Searching –Provided by TrimMainObjectSearch class –Search consists of a reverse-polish array of TrimSearchStackItem objects –A stack item is either a TrimSearchClause or a TrimSearchOperator –A TrimSearchClause is a method with parameters –A TrimSearchOperator is one of and, or, not –Search can also be specified using a “linear” string assignee:me and (createdOn:this month or updatedOn:this month) [0]: assignee:me [1]: createdOn:this month [2]: updatedOn:this month [3]: or [4]: and

11. TRIM User Forum 2010 TrimMainObjectSearch –Derives from IEnumerable, allowing foreach iteration –Properties ErrorMessage, Error, Database TrimType, BaseObjectTypes specified in constructor Icon Title FastCount SearchString SearchAsXML –Methods GetEnumerator(), for foreach support GetResultAsUriArray(…), useful for web apps SetSearchString(), returns TrimParserException ClearSearch() AddSearchClause() And() Or() Not() GetSearchAsStack() SetSearchFromStack()

12. TRIM User Forum 2010 TrimMainObjectSearch (cont.) –The main search stack can be “filtered” by specifying more criteria which are effectively combined with the main search using the and operator FilterString property SetFilterString() ClearFilters() AddFilterClause() GetFiltersAsArray() SetFiltersToDefault() SaveFiltersAsDefault() –The result set can also be sorted, using a subset of the search methods that are considered suitable for sorting SortString property SetSortString() ClearSort() AddSortItemAscending(…) AddSortItemDescending(…) GetSortAsArray() SetSortToDefault() SaveSortAsDefault()

13. TRIM User Forum 2010 TrimMainObjectSearch (cont.) –A number of “canned” selection methods are also available SelectByPrefix SelectFavorites(…) SelectByUserLabel(userLabelToSelectBy) SelectNone() SelectAll() SelectByUris(array of uris) SelectTopLevels(), for hierarchical objects SelectThoseWithin(parent), for hierarchical objects –The selection may also be assisted by specifying the purpose to which the list will be used, although not always SetPurpose(…) ClearPurpose() IsValidFromPurpose(TrimMainObject) –Can also do an “in-memory” compare, to see if an object would match the selection criteria contained in the search ItemMatches(TrimMainObjectToMatch)

14. TRIM User Forum 2010 TrimApplication –Represents the process which the TRIM SDK.NET is being called from –A “singleton”, with all properties and methods as static –Properties RuntimeEnvironment(Environments enum value) SDKVersion SoftwareVersion WebServerWorkPath ServiceType(windows, web, none) BinaryPath TemporaryPath HasUserInterface –Methods SetAsService() SetAsWebService(workPath) GetMessage(…) for accessing standard TRIM messages ProcessMessage(…), accessing TRIM substitution strings SetDefaultLanguage(…) GetDatabaseIds(servicedByWorkgroup)

15. TRIM User Forum 2010 Other Helper Classes –TrimIcon SDK.NET exposes the set of TRIM Icons, useful in certain situations Provides functionality based on the Icons enumeration Can also be constructed to represent the icon embedded within a Windows binary –TrimAccessControlList Class designed to simplify operations involving the updating and retrieval of access control information –TrimSecurityProfile Encapsulates a TrimSecurityLevel and an array of TrimSecurityCaveats Facilities simpler updates to the security profile of TRIM objects –TrimDateTime Encapsulates a date and time and is class used for all data and time fields in TRIM Extends System::DateTime by handling blank dates, blank times, and business calendar arithmetic Provides the usual date and time methods and properties

16. TRIM User Forum 2010 Object Model Helper Classes –Somewhat akin to “reflection”, there are a number of classes that expose the inherent behaviour of TRIM SDK elements –Provide captioning and capability discovery –ObjectDef Describes capabilities of a particular BaseObjectTypes value –PropertyDef Based on a value from the enumeration PropertyIds –Enum Based on a value from the enumeration AllEnumerations –EnumItem Allows you to access items with a particular enum. –CommandDef Based on a value from the enumeration CommandIds –SearchClauseDef Based on a value from the enumeration SearchClauseIds

17. TRIM User Forum 2010 Differences from COM –. NET supports constructors, so we use them db.GetRecord becomes new Record(db) –Since enumeration item values need to be qualified in.NET, we no longer have the two character prefix ctAuthor becomes ContactTypes.Author –Many of the “optional” features of objects have been implemented using an interface GetNotesInterface() allows for a more generic style of programming –Implements IDisposible, allowing for more efficient memory management COM Interop did not implement IDisposable... –No more “obsolete” properties and methods
