The Database (back_end) Classes There are 16 database (back-end) classes available in Release 4.1. An additional five database classes will be available with Release 4.5. The classes are as follows: Class Description NotesACL Represents a collection of all the access control list entries for a database. NotesACLEntry Represents a single entry in an access control list. NotesAgent Represents an agent. NotesDatabase Represents a Notes database. NotesDateTime Provides a means to translate between LotusScript and Notes date/time formatting. NotesDbDirectory Represents the database files on a server or the local machine. NotesDocument Represents a document in a database. NotesDocumentCollection Represents a collection of documents. NotesEmbeddedObject Represents embedded objects, links, and file attachments. NotesItem Represents a piece of data in a document. NotesLog Represents actions and errors that occur during a script’s execution. NotesNewsLetter A summary document that contains information from, or links to, several other documents. NotesRichTextItem Represents items that can contain rich text. NotesSession Root of Notes database objects—for global attributes, context, and persistent information. NotesView Represents a named view of a database. NotesViewColumn Represents a column of a view. NotesDateRange Represents a range of Notes date. NotesForm Represents a Notes form. NotesInternational Represents date-time settings from operating system. NotesName Represents a name. NotesTimer Represents a timer. Note The classes listed in italics will be available in Lotus Notes Release 4.5. Chapter 3: LotusScript Notes Classes 47
NotesACL Every NotesDatabase contains a NotesACL object representing that database’s access control list. To get NotesACL, use the ACL property in NotesDatabase. NotesACL also contains NotesACLEntry. The NotesDatabase class has three methods: QueryAccess, GrantAccess and RevokeAccess. You can use these methods to access and modify an ACL without declaring a NotesACL object. All you need to know is the name of the person, server, or group. Method Description AddRole Adds a role to an ACL. CreateACLEntry Creates an entry in the ACL with the name and level that you specify. When used with OLE automation, this method allows you to create a NotesACLEntry object without using the New method. DeleteRole Deletes a role from an ACL. GetEntry Given a name, finds its entry in an ACL. GetFirstEntry Returns the first entry in an ACL, usually the -Defaultentry. GetNextEntry Given an ACL entry, returns the next one. RenameRole Changes the name of a role. Save Saves the changes you’ve made to the ACL. If you don’t call Save before closing a database, the changes you’ve made to the ACL are lost. Property Description Parent Read-only. The database that owns an ACL. Role Read-only. All the roles defined in an access control list. UniformAccess Read-Write. Enables the “uniform access” option for the database. Note The property listed in italics will be available in Lotus Notes Release 4.5. NotesACLEntry To create a new NotesACLEntry object, we use the New method of NotesACLEntry or the CreateACLEntry method of NotesACL. The New method creates an entry in an ACL with the name and level that you 48 LotusScript for Visual Basic Programmers
