Class Schedule

java.lang.Object

net.named_data.jndn.encrypt.Schedule

public class Schedule
extends Object

Schedule is used to manage the times when a member can access data using two sets of RepetitiveInterval as follows. whiteIntervalList is an ordered set for the times a member is allowed to access to data, and blackIntervalList is for the times a member is not allowed.

Note:

This class is an experimental feature. The API may change.

Constructor Detail

Schedule

public Schedule()

Create a Schedule with empty whiteIntervalList and blackIntervalList.

Schedule

public Schedule(Schedule schedule)

Create a Schedule, copying values from the given schedule.

Parameters:

schedule - The Schedule to copy values from.

Method Detail

addWhiteInterval

public final Schedule addWhiteInterval(RepetitiveInterval repetitiveInterval)

Add the repetitiveInterval to the whiteIntervalList.

Parameters:

repetitiveInterval - The RepetitiveInterval to add. If the list already contains the same RepetitiveInterval, this does nothing.

Returns:

This Schedule so you can chain calls to add.

addBlackInterval

public final Schedule addBlackInterval(RepetitiveInterval repetitiveInterval)

Add the repetitiveInterval to the blackIntervalList.

Parameters:

repetitiveInterval - The RepetitiveInterval to add. If the list already contains the same RepetitiveInterval, this does nothing.

Returns:

This Schedule so you can chain calls to add.

getCoveringInterval

public final Schedule.Result getCoveringInterval(double timeStamp)

Get the interval that covers the time stamp. This iterates over the two repetitive interval sets and find the shortest interval that allows a group member to access the data. If there is no interval covering the time stamp, this returns false for isPositive and returns a negative interval.

Parameters:

timeStamp - The time stamp as milliseconds since Jan 1, 1970 UTC.

Returns:

An object with fields (isPositive, interval) where isPositive is true if the returned interval is positive or false if negative, and interval is the Interval covering the time stamp, or a negative interval if not found.

wireEncode

public final Blob wireEncode()

Encode this Schedule.

Returns:

The encoded buffer.

wireDecode

public final void wireDecode(ByteBuffer input)
                      throws EncodingException

Decode the input and update this Schedule object.

Parameters:

input - The input buffer to decode. This reads from position() to limit(), but does not change the position.

Throws:

EncodingException - For invalid encoding.

wireDecode

public final void wireDecode(Blob input)
                      throws EncodingException

Decode the input and update this Schedule object.

Parameters:

input - The input buffer to decode. This reads from position() to limit(), but does not change the position.

Throws:

EncodingException - For invalid encoding.

fromIsoString

public static double fromIsoString(String dateString)
                            throws EncodingException

Throws:

EncodingException

toIsoString

public static String toIsoString(double msSince1970)
