◆ signalStop()

void ripple::PerfLog_test::PerfLogParent::signalStop ( )

Definition at line 68 of file PerfLog_test.cpp.

◆ onPrepare()

void ripple::PerfLog_test::PerfLogParent::onPrepare ( )

overrideprivatevirtual

Override called during preparation.

Since all other Stoppable objects in the tree have already been constructed, this provides an opportunity to perform initialization which depends on calling into other Stoppable objects. This call is made on the same thread that called prepare(). The default implementation does nothing. Guaranteed to only be called once.

Reimplemented from ripple::Stoppable.

Definition at line 77 of file PerfLog_test.cpp.

◆ onStart()

void ripple::PerfLog_test::PerfLogParent::onStart ( )

overrideprivatevirtual

Override called during start.

Reimplemented from ripple::Stoppable.

Definition at line 82 of file PerfLog_test.cpp.

◆ onStop()

void ripple::PerfLog_test::PerfLogParent::onStop ( )

overrideprivatevirtual

Override called when the stop notification is issued.

The call is made on an unspecified, implementation-specific thread. onStop and onChildrenStopped will never be called concurrently, across all Stoppable objects descended from the same root, inclusive of the root.

It is safe to call isStopping, isStopped, and areChildrenStopped from within this function; The values returned will always be valid and never change during the callback.

The default implementation simply calls stopped(). This is applicable when the Stoppable has a trivial stop operation (or no stop operation), and we are merely using the Stoppable API to position it as a dependency of some parent service.

Thread safety: May not block for long periods. Guaranteed only to be called once. Must be safe to call from any thread at any time.

Reimplemented from ripple::Stoppable.

Definition at line 87 of file PerfLog_test.cpp.

◆ onChildrenStopped()

void ripple::PerfLog_test::PerfLogParent::onChildrenStopped ( )

overrideprivatevirtual

Override called when all children have stopped.

The call is made on an unspecified, implementation-specific thread. onStop and onChildrenStopped will never be called concurrently, across all Stoppable objects descended from the same root, inclusive of the root.

It is safe to call isStopping, isStopped, and areChildrenStopped from within this function; The values returned will always be valid and never change during the callback.

◆ isStopping()

bool ripple::RootStoppable::isStopping ( ) const

inherited

Definition at line 175 of file Stoppable.cpp.

◆ prepare()

void ripple::RootStoppable::prepare ( )

inherited

Prepare all contained Stoppable objects.

This calls onPrepare for all Stoppable objects in the tree. Calls made after the first have no effect. Thread safety: May be called from any thread.

Definition at line 181 of file Stoppable.cpp.

◆ start()

void ripple::RootStoppable::start ( )

inherited

Start all contained Stoppable objects.

The default implementation does nothing. Calls made after the first have no effect. Thread safety: May be called from any thread.

Definition at line 188 of file Stoppable.cpp.

◆ stop()

void ripple::RootStoppable::stop ( beast::Journal j )

inherited

Notify a root stoppable and children to stop, and block until stopped.

Has no effect if the stoppable was already notified. This blocks until the stoppable and all of its children have stopped. Undefined behavior results if stop() is called without a previous call to start(). Thread safety: Safe to call from any thread not associated with a Stoppable.

Definition at line 199 of file Stoppable.cpp.

Return true if start() was ever called.

Returns: true if we are stopping

Set the parent of this Stoppable.

Note: The Stoppable must not already have a parent. The parent to be set cannot not be stopping. Both roots must match.
