Member Function Documentation

void DcmQueryRetrieveProcessTable::addProcessToTable (  int  pid,
T_ASC_Association *  assoc
) 
 

adds a new child process to the process table.

Parameters:
pid process ID of the child process
assoc peer hostname and AEtitles are read from this object

void DcmQueryRetrieveProcessTable::cleanChildren (  OFBool  verbose = OFFalse  ) 
 

check if child processes have terminated and, if yes, remove them from the process table.

This method should be called regularly.

Parameters:
verbose if true, diagnostic output is printed to the console

size_t DcmQueryRetrieveProcessTable::countChildProcesses (   )  const [inline]
 

returns the number of child processes in the table

Returns:
number of child processes

References OFList< T >::size(), and table_.

OFBool DcmQueryRetrieveProcessTable::haveProcessWithWriteAccess (  const char *  calledAETitle  )  const
 

check if we have a child process that has write access to the given aetitle.

Used to enforce an ad-hoc rule that allows only one parallel association to negotiate storage presentation contexts for each storage area (aetitle)

void DcmQueryRetrieveProcessTable::removeProcessFromTable (  int  pid  )  [private]
 

remove the process with the given process ID from the table

Parameters:
pid process ID
