TimeTable

public TimeTable()

Method Details

builder

public static TimeTable.Builder builder()

Create a time table builder.

Time tables constructed via this builder are not equal to other instances unless all the fields specified are equal and TimeTable.Builder.id(Object) is explicitly set to equivalent objects.

Returns:

the builder

of

public static TimeTable of(Duration interval)

The time table.

Note: of(interval).equals(of(interval)) == false.

Parameters:

interval - the interval

Returns:

the time table

of

public static TimeTable of(Duration interval,
 Instant startTime)

The time table. Instances constructed via this method with the same interval and startTime will be equal.

Parameters:

interval - the interval

startTime - the start time

Returns:

the time table

clock

@Default
public Clock clock()

interval

public abstract Duration interval()

startTime

public abstract Optional<Instant> startTime()

blinkTable

@Default
public boolean blinkTable()

walk

public final <T> T walk(TableSpec.Visitor<T> visitor)
