Member Typedef Documentation

◆ Children

Definition at line 319 of file Stoppable.h.

Constructor & Destructor Documentation

◆ Manager()

ripple::PeerFinder::Manager::Manager ( Stoppable parent)
explicitprotected

Definition at line 288 of file PeerfinderManager.cpp.

◆ ~Manager()

virtual ripple::PeerFinder::Manager::~Manager ( )
virtualdefault

Destroy the object.

Any pending source fetch operations are aborted. There may be some listener calls made before the destructor returns.

Member Function Documentation

◆ setConfig()

virtual void ripple::PeerFinder::Manager::setConfig ( Config const &  config)
pure virtual

Set the configuration for the manager.

The new settings will be applied asynchronously. Thread safety: Can be called from any threads at any time.

Implemented in ripple::PeerFinder::ManagerImp.

◆ config()

virtual Config ripple::PeerFinder::Manager::config ( )
pure virtual

Returns the configuration for the manager.

Implemented in ripple::PeerFinder::ManagerImp.

◆ addFixedPeer()

virtual void ripple::PeerFinder::Manager::addFixedPeer ( std::string const &  name,
std::vector< beast::IP::Endpoint > const &  addresses 
)
pure virtual

Add a peer that should always be connected.

This is useful for maintaining a private cluster of peers. The string is the name as specified in the configuration file, along with the set of corresponding IP addresses.

Implemented in ripple::PeerFinder::ManagerImp.

◆ addFallbackStrings()

virtual void ripple::PeerFinder::Manager::addFallbackStrings ( std::string const &  name,
std::vector< std::string > const &  strings 
)
pure virtual

Add a set of strings as fallback IP::Endpoint sources.

Parameters
nameA label used for diagnostics.

Implemented in ripple::PeerFinder::ManagerImp.

◆ new_inbound_slot()

virtual std::shared_ptr<Slot> ripple::PeerFinder::Manager::new_inbound_slot ( beast::IP::Endpoint const &  local_endpoint,
beast::IP::Endpoint const &  remote_endpoint 
)
pure virtual

Add a URL as a fallback location to obtain IP::Endpoint sources.

Parameters
nameA label used for diagnostics. Create a new inbound slot with the specified remote endpoint. If nullptr is returned, then the slot could not be assigned. Usually this is because of a detected self-connection.

Implemented in ripple::PeerFinder::ManagerImp.

◆ new_outbound_slot()

virtual std::shared_ptr<Slot> ripple::PeerFinder::Manager::new_outbound_slot ( beast::IP::Endpoint const &  remote_endpoint)
pure virtual

Create a new outbound slot with the specified remote endpoint.

If nullptr is returned, then the slot could not be assigned. Usually this is because of a duplicate connection.

Implemented in ripple::PeerFinder::ManagerImp.

◆ on_endpoints()

virtual void ripple::PeerFinder::Manager::on_endpoints ( std::shared_ptr< Slot > const &  slot,
Endpoints const &  endpoints 
)
pure virtual

Called when mtENDPOINTS is received.

Implemented in ripple::PeerFinder::ManagerImp.

◆ on_closed()

virtual void ripple::PeerFinder::Manager::on_closed ( std::shared_ptr< Slot > const &  slot)
pure virtual

Called when the slot is closed.

This always happens when the socket is closed, unless the socket was canceled.

Implemented in ripple::PeerFinder::ManagerImp.

◆ on_failure()

virtual void ripple::PeerFinder::Manager::on_failure ( std::shared_ptr< Slot > const &  slot)
pure virtual

Called when an outbound connection is deemed to have failed.

Implemented in ripple::PeerFinder::ManagerImp.

◆ onRedirects()

virtual void ripple::PeerFinder::Manager::onRedirects ( boost::asio::ip::tcp::endpoint const &  remote_address,
std::vector< boost::asio::ip::tcp::endpoint > const &  eps 
)
pure virtual

Called when we received redirect IPs from a busy peer.

Implemented in ripple::PeerFinder::ManagerImp.

◆ onConnected()

virtual bool ripple::PeerFinder::Manager::onConnected ( std::shared_ptr< Slot > const &  slot,
beast::IP::Endpoint const &  local_endpoint 
)
pure virtual

Called when an outbound connection attempt succeeds.

The local endpoint must be valid. If the caller receives an error when retrieving the local endpoint from the socket, it should proceed as if the connection attempt failed by calling on_closed instead of on_connected.

Returns
true if the connection should be kept

Implemented in ripple::PeerFinder::ManagerImp.

◆ activate()

virtual Result ripple::PeerFinder::Manager::activate ( std::shared_ptr< Slot > const &  slot,
PublicKey const &  key,
bool  reserved 
)
pure virtual

Request an active slot type.

Implemented in ripple::PeerFinder::ManagerImp.

◆ redirect()

virtual std::vector<Endpoint> ripple::PeerFinder::Manager::redirect ( std::shared_ptr< Slot > const &  slot)
pure virtual

Returns a set of endpoints suitable for redirection.

Implemented in ripple::PeerFinder::ManagerImp.

◆ autoconnect()

virtual std::vector<beast::IP::Endpoint> ripple::PeerFinder::Manager::autoconnect ( )
pure virtual

Return a set of addresses we should connect to.

Implemented in ripple::PeerFinder::ManagerImp.

◆ buildEndpointsForPeers()

virtual std::vector<std::pair<std::shared_ptr<Slot>, std::vector<Endpoint> > > ripple::PeerFinder::Manager::buildEndpointsForPeers ( )
pure virtual

◆ once_per_second()

RootStoppable& ripple::Stoppable::getRoot ( )
inherited

Definition at line 214 of file Stoppable.h.

◆ setParent()

void ripple::Stoppable::setParent ( Stoppable parent)
inherited

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

Definition at line 43 of file Stoppable.cpp.

◆ isStopping()

bool ripple::Stoppable::isStopping ( ) const
inherited

Returns true if the stoppable should stop.

Definition at line 54 of file Stoppable.cpp.

◆ isStopped()

bool ripple::Stoppable::isStopped ( ) const
inherited

Returns
true if we are stopping

Definition at line 455 of file Stoppable.h.

◆ stopped()

void ripple::Stoppable::stopped ( )
protectedinherited

Called by derived classes to indicate that the stoppable has stopped.

Definition at line 72 of file Stoppable.cpp.

◆ onPrepare()

void ripple::Stoppable::onPrepare ( )
privatevirtualinherited

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 in ripple::ApplicationImp, ripple::OverlayImpl, ripple::test::Stoppable_test::Root, ripple::test::Stoppable_test::C, ripple::test::Stoppable_test::I, ripple::test::Stoppable_test::B, ripple::test::Stoppable_test::H, ripple::test::Stoppable_test::G, ripple::SHAMapStoreImp, ripple::test::Stoppable_test::A, ripple::PeerFinder::ManagerImp, ripple::perf::PerfLogImp, ripple::test::Stoppable_test::F, ripple::test::Stoppable_test::E, ripple::detail::LedgerCleanerImp, ripple::test::Stoppable_test::J, ripple::LoadManager, ripple::PerfLog_test::PerfLogParent, and ripple::test::Stoppable_test::D.

Definition at line 80 of file Stoppable.cpp.

◆ onStart()

void ripple::Stoppable::onStart ( )
privatevirtualinherited

◆ onStop()

void ripple::Stoppable::onStop ( )
privatevirtualinherited

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.

◆ onChildrenStopped()

void ripple::Stoppable::onChildrenStopped ( )
privatevirtualinherited

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.

The default implementation does nothing.

Definition at line 240 of file beast_PropertyStream.cpp.

◆ write() [2/2]

void beast::PropertyStream::Source::write ( PropertyStream stream,
std::string const &  path 
)
inherited

Parse the path and write the corresponding Source and optional children.

If the source is found, it is written. If the wildcard character '*' exists as the last character in the path, then all the children are written recursively.

Definition at line 252 of file beast_PropertyStream.cpp.

◆ find()

std::pair< PropertyStream::Source *, bool > beast::PropertyStream::Source::find ( std::string  path)
inherited

Parse the dot-delimited Source path and return the result.

The first value will be a pointer to the Source object corresponding to the given path. If no Source object exists, then the first value will be nullptr and the second value will be undefined. The second value is a boolean indicating whether or not the path string specifies the wildcard character '*' as the last character.

print statement examples "parent.child" prints child and all of its children "parent.child." start at the parent and print down to child "parent.grandchild" prints nothing- grandchild not direct discendent "parent.grandchild." starts at the parent and prints down to grandchild "parent.grandchild.*" starts at parent, print through grandchild children
