Method Summary

Modifier and Type	Method	Description
protected gov.aps.jca.dbr.DBR	getCompoundData(gov.aps.jca.Channel ch)	returns a compound DBR value of the channel, including value, alarm status, alarm severity, timestamp.
gov.aps.jca.dbr.TimeStamp	getTimeStamp(gov.aps.jca.Channel ch)	returns a timestamp for the channel request directly from EPICS server via compound DBR_TIME_XXXX.
static gov.aps.jca.dbr.TimeStamp	getTimeStamp(gov.aps.jca.dbr.DBR dbr)	returns a timestamp for the DBR if the DBR is of the tyep TIME.
static gov.aps.jca.dbr.DBRType	getTIMEType(gov.aps.jca.Channel ch)	returns the TIME DBRType of the channel that corresponds to its native primiary type.

Method Details

getTimeStamp

public gov.aps.jca.dbr.TimeStamp getTimeStamp(gov.aps.jca.Channel ch)
                                       throws gov.aps.jca.CAException,
gov.aps.jca.TimeoutException,
InterruptedException

returns a timestamp for the channel request directly from EPICS server via compound DBR_TIME_XXXX.

Parameters:

ch - the CA channel

Returns:

timestamp of the channel request

Throws:

gov.aps.jca.CAException

gov.aps.jca.TimeoutException

InterruptedException

getTimeStamp

public static gov.aps.jca.dbr.TimeStamp getTimeStamp(gov.aps.jca.dbr.DBR dbr)

returns a timestamp for the DBR if the DBR is of the tyep TIME.

Parameters:

dbr - the coumpound DBR value

Returns:

timestamp of the compound DBR

getCompoundData

protected gov.aps.jca.dbr.DBR getCompoundData(gov.aps.jca.Channel ch)
                                       throws gov.aps.jca.CAException,
gov.aps.jca.TimeoutException,
InterruptedException

returns a compound DBR value of the channel, including value, alarm status, alarm severity, timestamp. Implements the abstract base class method.

Overrides:

getCompoundData in class STSHandler

Parameters:

ch - channel

Returns:

a compound DBR value

Throws:

gov.aps.jca.CAException

gov.aps.jca.TimeoutException

InterruptedException

getTIMEType

public static gov.aps.jca.dbr.DBRType getTIMEType(gov.aps.jca.Channel ch)

returns the TIME DBRType of the channel that corresponds to its native primiary type. This method ensures the automatic type conversion between primiary types is always avoided during the channel request.

Parameters:

ch - the CA channel

Returns:

the TIME DBRType, i.e. DBR_TIME_XXXX
