function views_handler::get_field

Shortcut to get a handler's raw field value.

This should be overridden for handlers with formulae or other non-standard fields. Because this takes an argument, fields overriding this can just call return parent::get_field($formula)

Class

views_handler
Base handler, from which all the other handlers are derived. It creates a common interface to create consistency amongst handlers and data.

  // field.
