Detailed Description

Registry of per-thread Redo_applier instances, which can be all freed by calling reset().

This is used and owned by recv_sys. This wraps ut::Per_thread so recovery workers can reuse one Redo_applier per thread while keeping explicit recv_sys-controlled destruction instead of thread-exit destruction.

operator->()

ib::redo::Redo_applier * ib::redo::Redo_applier_registry::operator-> ( )

inline

Return the Redo_applier associated with the calling thread.

The applier is created on first access for that thread.

Returns

Redo_applier owned by this registry for the calling thread.

operator=()

Redo_applier_registry & ib::redo::Redo_applier_registry::operator= ( const Redo_applier_registry &  )

delete

reset()

void ib::redo::Redo_applier_registry::reset ( void  )

inline

Destroy all per-thread appliers owned by this registry.

Calling operator->() afterwards is a contract violation.
