Attribute Filter Script Functions

Attribute filter scripts can execute any standard JavaScript statements and functions. Additionally, attribute filter scripts use the AttributeFilter API to perform filter-specific operations. You must instantiate a new AttributeFilter object instance and then use it to invoke these methods, such as:

var filter = new AttributeFilter();
var csid = filter.Get(“Calling-Station-ID” );

These six AttributeFilter methods are provided:

  • new AttributeFilter()—Creates a new AttributeFilter object instance.
  • Get()—Gets the value of an attribute from the request or response packet.
  • Add()—Adds a new attribute value to the request or response packet.
  • Reset()—Deletes one or all values of an attribute.
  • Replace()—Deletes the value of an attribute and replaces it with a new value.
  • Execute()—Executes a static attribute filter.

    Note: Do not use the Execute() method to invoke a scripted attribute filter; a runtime error occurs.

Attribute filter scripts can also execute any of the methods of the DataAccessor class.

For more details about the AttributeFilter functions and methods, see AttributeFilter Object.
