Detailed Description

this class maintains a table of client processes.

For each client process, certain key parameters such as the peer hostname, AE titles, read/write access are stored along with the process ID.

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 ( )

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

This method should be called regularly.

size_t DcmQueryRetrieveProcessTable::countChildProcesses ( ) const

inline

returns the number of child processes in the 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
