/*********************************************************************************
|
|
* Description: This file handles the Data base functionality for the application.
|
|
* It acts as the DB abstraction layer for the application. It depends on helper classes
|
|
* which generate the necessary SQL. This sql is then passed to PEAR DB classes.
|
|
* The helper class is chosen in DBManagerFactory, which is driven by 'db_type' in 'dbconfig' under config.php.
|
|
*
|
|
* All the functions in this class will work with any bean which implements the meta interface.
|
|
* The passed bean is passed to helper class which uses these functions to generate correct sql.
|
|
*
|
|
* The meta interface has the following functions:
|
|
* getTableName() Returns table name of the object.
|
|
* getFieldDefinitions() Returns a collection of field definitions in order.
|
|
* getFieldDefintion(name) Return field definition for the field.
|
|
* getFieldValue(name) Returns the value of the field identified by name.
|
|
* If the field is not set, the function will return boolean FALSE.
|
|
* getPrimaryFieldDefinition() Returns the field definition for primary key
|
|
*
|
|
* The field definition is an array with the following keys:
|
|
*
|
|
* name This represents name of the field. This is a required field.
|
|
* type This represents type of the field. This is a required field and valid values are:
|
|
* int
|
|
* long
|
|
* varchar
|
|
* text
|
|
* date
|
|
* datetime
|
|
* double
|
|
* float
|
|
* uint
|
|
* ulong
|
|
* time
|
|
* short
|
|
* enum
|
|
* length This is used only when the type is varchar and denotes the length of the string.
|
|
* The max value is 255.
|
|
* enumvals This is a list of valid values for an enum separated by "|".
|
|
* It is used only if the type is ?enum?;
|
|
* required This field dictates whether it is a required value.
|
|
* The default value is ?FALSE?.
|
|
* isPrimary This field identifies the primary key of the table.
|
|
* If none of the fields have this flag set to ?TRUE?,
|
|
* the first field definition is assume to be the primary key.
|
|
* Default value for this field is ?FALSE?.
|
|
* default This field sets the default value for the field definition.
