Example: Edit a point class

A point class list in piconfig shows the following:

* (Ls - ) piconfig> @table piptcls
* (LS - PIPTCLS) piconfig> @mode list
* (Ls - PIPTCLS) piconfig> @ostru class
* (Ls - PIPTCLS) piconfig> @ostru set,...
* (Ls - PIPTCLS) piconfig> @select class=MyPtClass
* (Ls - PIPTCLS) piconfig> @ends
MyPtClass
base,classic
*----------

1. Add the attributes MyAttribute1 (string) and MyAttribute2 (int32) to this point class. To do this, create an attribute set, MyAttributeSet, as follows.

   @table piatrset
   @mode create
   @istru set
   @istru attrib,type,default
   @istru ...
   MyAttributeSet
   MyAttribute1,string,my default string
   MyAttribute2,int32,22

2. Check that the attribute was correctly created:

   @table piatrset
   @mode list
   @ostru set
   @ostru attrib,type,default
   @ostru ...
   @select set=MyAttributeSet
   @ends

   You should see:

   MyAttributeSet
   MyAttribute1,String,my default string
   MyAttribute2,Int32,22
   * End Repeat...
   *----------

3. Edit MyPtClass to include this attribute set. The system must be in stand-alone mode. Enter at a command prompt:

   piartool -sys -standalone on

4. In piconfig, define the attribute sets that should belong to the point class:

   @table piptcls
   @mode edit
   @istru class
   @istru set,...
   MyPtClass
   base,classic,MyAttributeSet

5. Check that these attributes now form MyPtClass.

   * (Ed - PIPTCLS) piconfig> @mode list
   * (Ls - PIPTCLS) piconfig> @ostru class
   * (Ls - PIPTCLS) piconfig> @ostru set,...
   * (Ls - PIPTCLS) piconfig> @select class=MyPtClass
   * (Ls - PIPTCLS) piconfig> @ends

   You should see:

   MyPtClass
   base,classic,MyAttributeSet
   *----------

6. To see all attributes that are in this point class, enter:

   @table pipoint
   @ptclass MyPtClass
   @?atr

7. Place the system back in normal mode:

   piartool -sys -standalone off
