Member Function Documentation

ccsCOMPL_STAT tcsmonSched::checkGidAttr (  node *    n )  [protected]

Checks a control attribute. Reads the database pointed by the node and compares it with its okValue. Parameters: n  node to check Returns: SUCCESS or FAILURE

void tcsmonSched::print (  void    )

ccsCOMPL_STAT tcsmonSched::getType (  char *    symAddr, node &    n )

Get info about the DB point passed. Gets type and direct address of <symAddr> and updates the node attribute with this info. Parameters: symAddr  Symbolic address of the point where to get the data n  node to update with data gathered from <symAddr> Returns: SUCCESS or FAILURE

ccsCOMPL_STAT tcsmonSched::addNode (  node *    n )

Add a new node group or a node to a node group. Takes the node passed as a parameter and creates a new node group (if Node->gid>0) or adds a node to the lastGroup created. If the node is a group definition adds the node to vector vTable and its period to vector vPeriod (used later by generateMap) it also increments mPeriod[period] entry.. Parameters: Node  The node to add Returns: SUCCESS or FAILURE

ccsCOMPL_STAT tcsmonSched::readAttr (  node *    )

ccsCOMPL_STAT tcsmonSched::fitsLog (  node *    )

FITS log a group. Logs the FITS keyword and DB value of a single node. Parameters: node  the node to log. Returns: SUCCESS or FAILURE

ccsCOMPL_STAT tcsmonSched::generateMap (  void    )

Create the logging time table (populate mTable map). mTable consist of pairs $(time, group)$, where time is the time left to start the {next} logging cycle (a logging cycle logs all DB attrs from a group definition). The table is populated as follows: \begin{itemize} \item The size of the table is the common denomitator of all logging periods. This is the period $T$ of the time table. \item Each logging group is allocated in the time table $T/p$ times ($p$ is the logging group period). The logging time for each logging group $Gi$ with logging period $p$ is computed as follows: Given $N_{p}$ (the number of groups with period $p$).\ $f = p/N_{p}$ \ $time_{0} = f * i, i=0 \ldots N_{p-1}$\ $time_{i} = time_{ i-1}+f*N_{p}$\ $time_{i} < T$ \ \item In case of collision an arbitrary offset of 3.7(s) is added until the collision is cleared. \end{itemize}

ccsCOMPL_STAT tcsmonSched::readFile (  const char *    )

Reads and parses an input file. The file is first lokked up at INTROOT/config and then at VLTROOT/config. Parameters: file  The name of the file to read. Returns: SUCCESS or FAILURE

vltUINT32 tcsmonSched::cycle (  void    )

Performs a logging cycle. This functions reads an mTable entry (time, group), check the group's control attribute and logs the group's values. Returns: The time (us) for the next cycle.

ccsCOMPL_STAT tcsmonSched::reset (  void    )

ccsCOMPL_STAT tcsmonSched::listTable (  char *    name )

bool tcsmonSched::OK (  void    )  [inline]

Member Data Documentation

vector<nodeGroup*> tcsmonSched::vTable [private]

Vector which holds Group definitions for logging.

map<vltUINT16,vltUINT16> tcsmonSched::mPeriod [private]

Indexed by period, returns how many groups logs on a given period.

map<vltUINT32, nodeGroup*> tcsmonSched::mTable [private]

mTable is a map. The keys (vltINT32) are timestamps signaling when to read the {nex}t logging group. The elements are the node group to log {now}.

ifstream tcsmonSched::ifile [private]

vltUINT16 tcsmonSched::period [private]

map<vltUINT32, nodeGroup*>::iterator tcsmonSched::mi [private]

bool tcsmonSched::ok [private]
