virtual bool drizzled::plugin::StorageEngine::alwaysRegisterForXaTransaction | ( | ) | const [inline, virtual] |
Returns true if the class should be registered for every XA transaction regardless of whether the class modifies the server's state.
As an example, the XaTransactionApplier plugin class returns true for this virtual method. Even though it does not change the result of the transaction (it simply is logging the changes made by other resource managers), the applier plugin should be enlisted in all XA transactions in order to be able to rollback or recover its logging activity properly.
Implements drizzled::plugin::MonitoredInTransaction.
Reimplemented in drizzled::plugin::TransactionalStorageEngine, and drizzled::plugin::XaStorageEngine.
Definition at line 440 of file storage_engine.h.
virtual const char** drizzled::plugin::StorageEngine::bas_ext | ( | ) | const [pure virtual] |
If frm_error() is called then we will use this to find out what file extentions exist for the storage engine. This is also used by the default rename_table and delete_table method in Cursor.cc.
For engines that have two file name extentions (separate meta/index file and data file), the order of elements is relevant. First element of engine file name extentions array should be meta/index file extention. Second element - data file extention. This order is assumed by prepare_for_repair() when REPAIR Table ... USE_FRM is issued.
Implemented in Function, HailDBEngine, Schema, drizzled::plugin::SEAPITester, and TableProtoTesterEngine.
