Detailed Description

The parameters affecting all feeds involved into market data processing.

Definition at line 935 of file FeedSettings.h.

Constructor & Destructor Documentation

FeedSettings() [1/2]

FeedSettings ( SettingChangeController * controller = nullptr )

inline

Initializes the instance with the default values.

Definition at line 939 of file FeedSettings.h.

FeedSettings() [2/2]

FeedSettings ( const FeedSettings & other )

inline

Initializes the instance as a copy of the other one.

Definition at line 953 of file FeedSettings.h.

Member Function Documentation

engine() [1/2]

NetFeedEngine * engine ( ) const

inline

Returns the Feed Engine used by the handler.

Returns

Pointer to the configured Feed Engine, or nullptr if it was explicitly cleared.

Note

Unless replaced, this method returns an internally owned default Feed Engine backed by a SocketFeedEngine and internal worker threads. Do not delete the default engine or invoke NetFeedEngine::process on it.

Definition at line 1091 of file FeedSettings.h.

engine() [2/2]

FeedSettings & engine ( NetFeedEngine * engine )

inline

Replaces the default Feed Engine with an explicit instance.

Parameters

engine

Feed Engine to bind, or nullptr to leave the handler without a Feed Engine.

Returns

Reference to this object.

Exceptions

std::runtime_error

If the setting belongs to a handler that is processing market data or being configured from another source.

Note

The handler does not take ownership of an explicit Feed Engine. Keep the instance alive while it is bound and run its processing logic from the application.

Passing nullptr causes the next Handler::start() attempt to fail, reports Issue::OperationFailure through HandlerListener::onError, and leaves the handler stopped. Bind a valid engine before starting market data processing.

Definition at line 1107 of file FeedSettings.h.

feedANetworkInterfaces()

FeedSettings & feedANetworkInterfaces ( const std::string & interfaces )

inline

Specifies one or more network interfaces on which to join multicast groups referring to primary (A) feeds.

Multiple interfaces can be specified using semi-colon as a delimiter.

The given member is kind of batch set-up. Manual specification of network interfaces for a particular feed is also possible through the corresponding parameters.

Exceptions

std::runtime_error

If the setting belongs to a handler that is processing market data or being configured from another source.

Definition at line 977 of file FeedSettings.h.

feedBNetworkInterfaces()

FeedSettings & feedBNetworkInterfaces ( const std::string & interfaces )

inline

Specifies one or more network interfaces on which to join multicast groups referring to secondary (B) feeds.

Multiple interfaces can be specified using semi-colon as a delimiter.

The given member is kind of batch set-up. Manual specification of network interfaces for a particular feed is also possible through the corresponding parameters.

Exceptions

std::runtime_error

If the setting belongs to a handler that is processing market data or being configured from another source.

Definition at line 998 of file FeedSettings.h.

historicalFeeds() [1/2]

TcpRecoveryFeedSettings & historicalFeeds ( )

inline

The settings related to historical (TCP Recovery) feeds.

Definition at line 1080 of file FeedSettings.h.

historicalFeeds() [2/2]

const TcpRecoveryFeedSettings & historicalFeeds ( ) const

inline

The settings related to historical (TCP recovery) feeds.

Definition at line 1074 of file FeedSettings.h.

incrementalFeeds() [1/2]

RealtimeFeedSettings & incrementalFeeds ( )

inline

The settings related to incremental feeds.

Definition at line 1032 of file FeedSettings.h.

incrementalFeeds() [2/2]

const RealtimeFeedSettings & incrementalFeeds ( ) const

inline

The settings related to incremental feeds.

Definition at line 1026 of file FeedSettings.h.

instrumentFeeds() [1/2]

MulticastRecoveryFeedSettings & instrumentFeeds ( )

inline

The settings related to instrument feeds.

Definition at line 1044 of file FeedSettings.h.

instrumentFeeds() [2/2]

const MulticastRecoveryFeedSettings & instrumentFeeds ( ) const

inline

The settings related to instrument feeds.

Definition at line 1038 of file FeedSettings.h.

mboSnapshotFeeds() [1/2]

MulticastRecoveryFeedSettings & mboSnapshotFeeds ( )

inline

The settings related to snapshot feeds.

Definition at line 1068 of file FeedSettings.h.

mboSnapshotFeeds() [2/2]

const MulticastRecoveryFeedSettings & mboSnapshotFeeds ( ) const

inline

The settings related to snapshot feeds.

Definition at line 1062 of file FeedSettings.h.

operator=()

FeedSettings & operator= ( const FeedSettings & other )

inline

Re-initializes the instance as a copy of the other one.

Exceptions

std::runtime_error

If the setting belongs to a handler that is processing market data or being configured from another source.

Definition at line 1118 of file FeedSettings.h.

packetMaxSize() [1/2]

PacketSize packetMaxSize ( ) const

inline

Max size for network packet transmitted by MDP.

Note

Default value is '1420'.

Definition at line 1010 of file FeedSettings.h.

packetMaxSize() [2/2]

FeedSettings & packetMaxSize ( PacketSize value )

inline

Max size for network packet transmitted by MDP.

Exceptions

std::runtime_error

If the setting belongs to a handler that is processing market data or being configured from another source.

Definition at line 1018 of file FeedSettings.h.

snapshotFeeds() [1/2]

MulticastRecoveryFeedSettings & snapshotFeeds ( )

inline

The settings related to snapshot feeds.

Definition at line 1056 of file FeedSettings.h.

snapshotFeeds() [2/2]

const MulticastRecoveryFeedSettings & snapshotFeeds ( ) const

inline
