Member Function Documentation

dataWaitTime() [1/2]

UInt32 dataWaitTime ( ) const

inline

Defines amount of time Feed Engine spends on socket waiting for I/O while running master processing loop.

Time is measured in milliseconds.

Note

Default value is '10'.

Warning

Given parameter significantly affects Handler's responsiveness and load onto CPU!

Definition at line 145 of file FeedEngine.h.

dataWaitTime() [2/2]

void dataWaitTime ( UInt32 value )

inline

Sets dataWaitTime.

See also

dataWaitTime.

Definition at line 151 of file FeedEngine.h.

socketBufferSize() [1/2]

UInt32 socketBufferSize ( ) const

inline

Defines size of receiving buffer in bytes for sockets.

Note

Default value is 8 MiB.

Definition at line 178 of file FeedEngine.h.

socketBufferSize() [2/2]

void socketBufferSize ( UInt32 value )

inline

Sets udpSocketBufferSize.

See also

udpSocketBufferSize.

Definition at line 184 of file FeedEngine.h.

spinBeforeIdleTime() [1/2]

UInt32 spinBeforeIdleTime ( ) const

inline

Defines amount of time Feed Engine keeps cycling before going to sleep when no useful activity can be done.

Time is measured in milliseconds.

Note

Default value is '1'.

Warning

Given parameter has direct influence onto CPU load!

Definition at line 164 of file FeedEngine.h.

spinBeforeIdleTime() [2/2]

void spinBeforeIdleTime ( UInt32 value )

inline

Sets redundancySpinTime.

See also

redundancySpinTime.

Definition at line 170 of file FeedEngine.h.

threadAffinity() [1/2]

ThreadAffinity & threadAffinity ( )

inline

Defines set of CPUs allowed for each working thread to be executed on while processing market data by Handlers bound to Feed Engine instance which is configured by given settings.

Note

By default set is empty thus allowing threads to be executed on any CPU available in the system.

Definition at line 117 of file FeedEngine.h.

threadAffinity() [2/2]

const ThreadAffinity & threadAffinity ( ) const

inline

Defines set of CPUs allowed for each working thread to be executed on while processing market data by Handlers bound to Feed Engine instance which is configured by given settings.

Note

By default set is empty thus allowing threads to be executed on any CPU available in the system.

Definition at line 105 of file FeedEngine.h.

threadCount() [1/2]

UInt32 threadCount ( ) const

inline

Number of working threads to be used by feed engine.

Note

Default value is '1'.

Definition at line 125 of file FeedEngine.h.

threadCount() [2/2]

void threadCount ( UInt32 value )

inline

Sets threadsCount.

See also

threadsCount.

Definition at line 131 of file FeedEngine.h.

toString()

std::string toString

(

)

const

Returns the string representation.
