New Class Wizard

Package to which the new class belongs. You can select an existing package name or enter a new name. If you enter a new name, the new package is automatically created when you save your class definition. The only punctuation marks that property names can contain are a dot (.) and a leading percent sign (%).

For more information on packages, see Package Options.

Name of your new class. This must be a valid class name and must not conflict with the name of a previously defined class. Note that you cannot change this class name later.

See Rules and Guidelines for Identifiers.

(optional) Description of the new class. This description is used when the class' documentation is displayed in the online class library documentation.

A description may include HTML formatting tags. See Creating Class Documentation in Defining and Using Classes.

Create a definition for a persistent class. Persistent objects can be stored in the database.

Create a definition for a serial class. Serial objects can be embedded in persistent objects to create complex data types such as addresses.

Create a definition for a registered class. Registered objects are not stored in the database.

Create a definition for an abstract class with no superclass.

Create a definition for a data type class. A data type class is used to create user-defined data types.

Create a definition for a %CSP.PageOpens in a new tab class. A CSP class is used to create a CSP event handling class. This is a programmatic way to create CSP Pages or to respond to HTTP events (for example, to create an XML server). Using CSP files with InterSystems IRIS is not recommended.

Extend an existing class: check Extends and enter (or choose from a list) the name of an existing superclass.

The data type used by clients to represent this data enter a client application.

The data type used by ODBC or JDBC to represent this data type. Choose a type that corresponds to how you want this data type to appear to ODBC/JDBC based applications.

The SQL Category used by the InterSystems SQL Engine when it performs logical operations on this data type.

(optional) For a persistent class, enter the SQL username to be the owner of the new class. This username controls privileges when this class is used via SQL. If this field is left blank, then the default owner, _system, is used.

(optional) For a persistent class, enter a name to be used for the SQL table that corresponds to this class. If this field is left blank, then the SQL table name is identical to the class name. If the class name is not a valid SQL identifier, you must enter an SQL table name here.

(optional) If selected, the class is XML-enabled; that is, it has the ability to project itself as an XML document. It can also be used in Web Service methods. This is equivalent to adding the %XML.AdaptorOpens in a new tab class to the class' superclass list.

For more information see Using XML Tools as well as Creating Web Services and Web Clients.

This feature is not supported in InterSystems IRIS.

(optional) If you select this option, your new class supports automatic data population. This is equivalent to adding the %Library.PopulateOpens in a new tab class to the class' superclass list.

Automatic data population allows you to easily create random data with which you can test the operation of your class. To populate a class, compile it and then execute the class' Populate method (inherited from the %Library.PopulateOpens in a new tab class). For example, using the Terminal:

 Do ##class(MyApp.Person).Populate(100)

For more information see InterSystems IRIS Data Population Utility.

Specifies what the content type served by this CSP class is. The available options are HTML or XML. This option is used to set the value of the CONTENTTYPE parameter of the new class to text/html or text/xml respectively. You can later change this to whatever value you want.
