Метод	Описание
__call ( string $name, array $arguments ) : ORM	Magic method to capture calls to undefined class methods.
__callStatic ( string $name, array $arguments ) : ORM	Magic method to capture calls to undefined static class methods.
__get ( $key )	--------------------- //
__isset ( $key )
__set ( $key, $value )
__unset ( $key )
_add_having_no_value ( $column_name, $operator )	Internal method to add a HAVING clause with no parameters(like IS NULL and IS NOT NULL)
_add_having_placeholder ( $column_name, $separator, $values )	Internal method to add a HAVING clause with multiple values (like IN and NOT IN)
_add_id_column_conditions ( &$query )	Add a WHERE clause for every column that belongs to the primary key
_add_where_no_value ( $column_name, $operator )	Add a WHERE clause with no parameters(like IS NULL and IS NOT NULL)
_add_where_placeholder ( $column_name, $separator, $values )	Add a WHERE clause with multiple values (like IN and NOT IN)
_setup_limit_clause_style ( string $connection_name )	Detect and initialise the limit clause style ("SELECT TOP 5" / ".
as_array ( )	Return the raw data wrapped by this ORM instance as an associative array. Column names may optionally be supplied as arguments, if so, only those keys will be returned.
avg ( $column )	Tell the ORM that you wish to execute a AVG query.
clear_cache ( $table_name = null, $connection_name = self::DEFAULT_CONNECTION )	Clear the query cache
configure ( string $key, mixed $value = null, string $connection_name = self::DEFAULT_CONNECTION )	Pass configuration settings to the class in the form of key/value pairs. As a shortcut, if the second argument is omitted and the key is a string, the setting is assumed to be the DSN string used by PDO to connect to the database (often, this will be the only configuration required to use Idiorm). If you have more than one setting you wish to configure, another shortcut is to pass an array of settings (and omit the second argument).
count ( $column = '*' )	Tell the ORM that you wish to execute a COUNT query.
count_null_id_columns ( )	Counts the number of columns that belong to the primary key and their value is null.
create ( $data = null )	Create a new, empty instance of the class. Used to add a new row to your database. May optionally be passed an associative array of data to populate the instance. If so, all fields will be flagged as dirty so all will be saved to the database when save() is called.
delete ( )	Delete this record from the database
delete_many ( )	Delete many records from the database
distinct ( )	Add a DISTINCT keyword before the list of columns in the SELECT query
find_array ( ) : array	Tell the ORM that you are expecting multiple results from your query, and execute it. Will return an array, or an empty array if no rows were returned.

find_one ( $id = null )	Tell the ORM that you are expecting a single result back from your query, and execute it. Will return a single instance of the ORM class, or false if no rows were returned.
find_result_set ( ) : IdiormResultSet	Tell the ORM that you are expecting multiple results from your query, and execute it. Will return a result set object containing instances of the ORM class.
for_table ( string $table_name, string $connection_name = self::DEFAULT_CONNECTION ) : ORM	Despite its slightly odd name, this is actually the factory method used to acquire instances of the class. It is named this way for the sake of a readable interface, ie ORM::for_table('table_name')->find_one()-> etc. As such, this will normally be the first method called in a chain.
