Detailed Description

A write only view on top of node container.

Constructor & Destructor Documentation

NodeContainerModifier()

catapult::ionet::NodeContainerModifier::NodeContainerModifier	(	NodeContainerData &	nodeContainerData,
		utils::SpinReaderWriterLock::ReaderLockGuard &&	readLock
	)

Creates a view around nodeContainerData with lock context readLock.

Member Function Documentation

add()

bool catapult::ionet::NodeContainerModifier::add	(	const Node &	node,
		NodeSource	source
	)

Adds a node to the collection with source.

Note

Node sources can be promoted but never demoted.

Here is the call graph for this function:

addConnectionStates()

void catapult::ionet::NodeContainerModifier::addConnectionStates	(	ServiceIdentifier	serviceId,
		ionet::NodeRoles	role
	)

Adds connection states for the service identified by serviceId to all nodes with role.

Here is the caller graph for this function:

ageConnectionBans()

void catapult::ionet::NodeContainerModifier::ageConnectionBans	(	ServiceIdentifier	serviceId,
		uint32_t	maxConnectionBanAge,
		uint32_t	numConsecutiveFailuresBeforeBanning
	)

Ages all connection bans for the service identified by serviceId given maxConnectionBanAge and numConsecutiveFailuresBeforeBanning.

ageConnections()

void catapult::ionet::NodeContainerModifier::ageConnections	(	ServiceIdentifier	serviceId,
		const utils::KeySet &	identities
	)

Ages all connections for the service identified by serviceId for nodes with identities.
