_createTable

Method to load and return a model object.

_createTable(string $name, string $prefix = 'Table', array $config = array()) : \JTable|boolean
inherited
since

3.0

see \JTable::getInstance()

Arguments

$name

stringThe name of the view

$prefix

stringThe class prefix. Optional.

$config

_getList

Gets an array of objects from the results of database query.

_getList(string $query, integer $limitstart, integer $limit) : array<mixed,object>
inherited
since

3.0

throws

\RuntimeException

Arguments

$query

stringThe query.

$limit

integerThe number of records.

Response

array<mixed,object>An array of results.

_getListCount

Returns a record count for the query.

_getListCount(\JDatabaseQuery|string $query) : integer
inherited

Note: Current implementation of this method assumes that getListQuery() returns a set of unique rows, thus it uses SELECT COUNT(*) to count the rows. In cases that getListQuery() uses DISTINCT then either this method must be overriden by a custom implementation at the derived Model Class or a GROUP BY clause should be used to make the set unique.

$query

integerNumber of rows for query.
