2 cjb


Commandreturn
CommandReturn

  • Standard return object for client commands

    • Indicates success or failure

    • May contain

      • Strings

      • Other CommandReturn objects

      • Event descriptions

    • Serialized object (XML) is returned

3 cjb


Commandsequencer
CommandSequencer

  • Commands from client to subsystem

  • Layer above lower level RPC

  • Supports

    • Status of command

    • Block on command

    • Results of command

  • Subsystem reference 481s008

4 cjb


Core

  • ArgumentList

    • Used to pass arguments from client to subsystem

  • BitArray

    • Supports arrays of packed bits and bit fields

  • Configuration

    • Reads parameters from LBT.conf

5 cjb


Core cont
Core (cont)

  • Conversions

    • Provides unit conversions

  • LoadMonitor

    • Used when starting subsystems

  • Shm

    • Supports access to shared memory segments

  • Socket

    • Socket support

6 cjb


Core cont1
Core (cont)

  • Signal

    • Simple signal handling

  • Synchronization (IMutex, MsgQueue, PMutex, Semaphore)

    • Provides mutexes, semaphores and condition synchronization

  • SysLog

    • syslog support

7 cjb


Core cont2
Core (cont)

  • System

    • Gets IP addresses and PIDs

  • SystemClock

    • Get time, MJD, calendar time; do delays

  • Thread

    • Support for POSIX threads in TCS context

  • XML support

    • Xerces based XML parsing

8 cjb


Datadictionary
DataDictionary

  • Supports reflective memory and events

    • Writing (ddsconfig) and reading binary definition files

9 cjb


Eventhandler
EventHandler

  • Event class

  • Logs events to local flat file

  • Interfaces with the LSS

10 cjb


Networkconfig
NetworkConfig

  • Handles starting/stopping TCS networks and subsystems

    • netconfig

    • networkserver

11 cjb


Reflectivememory
ReflectiveMemory

  • Reflective memory network support

    • gshmconfig

    • gshmserver

12 cjb


RPC

  • Underlying layer for all TCS communications

    • rpcconfig

    • rpcserver

    • RPC class

13 cjb


Setvalue
SetValue

  • Reads and writes from/to reflective memory

    • Gtype class

    • SetValueInterface class

  • Provides reflective memory write protection

    • Only owning subsystem may write its memory

  • Metadata retrieval

14 cjb


Telemetryclient
TelemetryClient

  • Hook for subsystems to interface to the TEL subsystem

    • startStream
