As an aid to understanding the ProcessClass, it is useful to organize its methods into two categories according to their expected use--the primary interface and the virtual methods. This organization reflects what we believe is typical use of the ProcessClass methods.

**Non-Virtual Methods**

**Housekeeping (one-time) Use:**

|  | Init | initialize the ProcessClass object |
|  | AddRange (i) | add a range limit to the active sort order |
|  | AddSortOrder (i) | add a sort order |
|  | AppendOrder (i) | refine the active sort order |
|  | SetProgressLimits | calibrate the StepClass progress monitor |
|  | Kill (v) | shut down the ProcessClass object |

**Mainstream Use:**

|  | Open (i) | open the view |
|  | Next (v) | get the next result set element |
|  | Previous (iv) | get the previous result set element |
|  | PrimeRecord (i) | prepare a record for adding |
|  | ValidateRecord (iv) | validate the current result set element |
|  | SetFilter (i) | specify a filter for the active sort order |
|  | SetSort (iv) | set the active sort order |
|  | ApplyFilter (i) | range limit and filter the result set |
|  | ApplyOrder (i) | sort the result set |
|  | ApplyRange (i) | conditionally range limit and filter the result set |
|  | Close (i) | close the view |

**Occasional Use:**

|  | GetFreeElementName (i) | return the free element field name |
|  | Reset (v) | reposition to the first result set element |
|  | SetOrder (iv) | replace the active sort order |

(i)These methods are inherited from the ViewManager class.

(v)These methods are also Virtual.

**Virtual Methods**

Typically you will not call these methods directly--the Non-Virtual Methods call them. However, we anticipate you will often want to override these methods, and because they are virtual, they are very easy to override. These methods do provide reasonable default behavior in case you do not want to override them.

|  | Next | get the next result set element |
|  | Previous (i) | get the previous result set element |
|  | Reset | reposition to the first result set element |
|  | SetSort (i) | set the active sort order |
|  | ValidateRecord (i) | validate the current result set element |
|  | Kill | Shut down the ProcessClass object |

(i)These methods are inherited from the ViewManager class.
