DESCRIPTION

If one wishes to enforce table locks, then a LockQuery would be used to specify and set up those table locks.

Use UnlockQuery to release table locks.

Constructor & Destructor Documentation

LockQuery::__construct (   $tablelocks)

Constructor. See affiliated setter functions for expanded descriptions as to the kinds of input that these arguments expect.

Parameters
$tablelocksarray The tables to be locked and their lock type specification

Member Function Documentation

LockQuery::makeQuery ( $query_string,
$dtype_string 
)

Used by the MysqlFacet class when it is executing the query.

Parameters
&$query_stringstring The generated SQL query
&$dtype_Stringstring The generated input data type string
LockQuery::setTablelocks (   $tablelocks)

Defines the kinds of table locks that should be set.

This function expects an array of arrays in which each array has two values: the first being the name of the table to lock, and the second being the lock type, either Query::$LOCK_R for a read lock and Query::$LOCK_W for a write lock.
