Interface Time

All Superinterfaces:

Cloneable, Field, Serializable

All Known Implementing Classes:

TimeField

public interface Time
extends Field

A RepeatTime represents a t= field contained within a TimeDescription. A RepeatTime specifies the start and stop times for a SessionDescription. Note: this class uses java.util.Date objects. SDP messages encode time in NTP format. To convert between them use SdpFactory.getDateFromNtp(long) and SdpFactory.getNtpTime(Date). Quoting from RFC 2327: Multiple "t=" fields may be used if a session is active at multiple irregularly spaced times; each additional "t=" field specifies an additional period of time for which the session will be active. If the session is active at regular times, an "r=" field (see below) should be used in addition to and following a "t=" field - in which case the "t=" field specifies the start and stop times of the repeat sequence. Please refer to IETF RFC 2327 for a description of SDP.

Method Detail

getStart

Date getStart()
              throws SdpParseException

Returns the start time of the conference/session.

Returns:

the date

Throws:

SdpParseException

setStart

void setStart(Date start)
              throws SdpException

Sets the start time of the conference/session.

Parameters:

start - start - the start time for the session.

Throws:

SdpException - if the date is null

getStop

Date getStop()
             throws SdpParseException

Returns the stop time of the session

Returns:

the stop time of the session.

Throws:

SdpParseException

setStop

void setStop(Date stop)
             throws SdpException

Sets the stop time of the session.

Parameters:

stop - start - the start time

Throws:

SdpException - if the date is null

isZero

boolean isZero()

Returns whether the start and stop times were set to zero (in NTP).

Returns:

boolean

setZero

void setZero()

Sets the start and stop times to zero (in NTP).

getTypedTime

boolean getTypedTime()

Returns whether the field will be output as a typed time or a integer value. Typed time is formatted as an integer followed by a unit character. The unit indicates an appropriate multiplier for the integer. The following unit types are allowed. d - days (86400 seconds) h - hours (3600 seconds) m - minutes (60 seconds) s - seconds ( 1 seconds)

Returns:

true, if the field will be output as a typed time; false, if as an integer value.

setTypedTime

void setTypedTime(boolean typedTime)

Sets whether the field will be output as a typed time or a integer value. Typed time is formatted as an integer followed by a unit character. The unit indicates an appropriate multiplier for the integer. The following unit types are allowed. d - days (86400 seconds) h - hours (3600 seconds) m - minutes (60 seconds) s - seconds ( 1 seconds)

Parameters:

typedTime - typedTime - if set true, the start and stop times will be output in an optimal typed time format; if false, the times will be output as integers.
