Up: Object-Oriented Access to Database Records

Source Code

This class represents the top level functionality of the Family Tree. Only a single instance of this class is created in the common initialization code and assigned to the global variable $tree. Its primary purpose is to provide a set of factory methods for obtaining existing instances of classes derived from class Record in such a way as to avoid creating duplicate instances.

It also provides access to the global settings table defined by Legacy Family Tree©, although that table is not used by this application. This class provides access to the information in the table tblHR.

      CREATE TABLE `tblHR` (
         `Item`       VARCHAR(10) NOT NULL DEFAULT '',
         `Setting`    VARCHAR(255) DEFAULT NULL,
          PRIMARY KEY (`Item`) )
      ENGINE=InnoDB DEFAULT CHARSET=utf8

This class is not derived from class Record but implements part of the same interface.
