From IHRIS Wiki
Revision as of 08:50, 10 November 2009 by Litlfred (talk | contribs)

This article describes the abstract class I2CE_List.

Base object for dealing with lists of data. This is an abstract object with base code for many of the I2CE_Form interface methods. It is used for many of the list database objects such as AcademicLevel and District . It assumes all lists have a code field and by default a description field but this can be overwritten by certain objects like Cadre . @abstract

Constants

I2CE_List::MAIN_FIELD

The main field name used for display a description of a record. Defined as: "name"

I2CE_List::SEC_FIELD

The secondary field name used for displaying a description of a record in combination with the MAIN_FIELD. Defined as: null

I2CE_List::SORT_FIELD

The sort field name to be used for sorting the display list. This can't be used with the SEC_FIELD option for display. Defined as: null

Variables

$cache

An array to cache lookup entries Any lookups done to the database will be cached in this static array so additional lookups using the same id won't have to access the database. @static

name()

Return the display name for this list object. This will return the same value as lookup() but from the current object instead of from the database.
