Method Summary

Modifier and Type	Method and Description
boolean	abuts(ChronoInterval<PlainDate> other) Queries if this interval abuts the other one such that there is neither any overlap nor any gap between.
boolean	contains(ChronoInterval<PlainDate> other) Does this interval contain the other one?
boolean	isBefore(ChronoInterval<PlainDate> other) Is this interval before the other one?
boolean	isEmpty() A calendar interval is never empty.
boolean	isFinite() A calendar interval is always finite.
boolean	isSimultaneous(T other) Queries if this object and given object have the same position on the time axis.
Stream<PlainDate>	streamDaily() Obtains a stream iterating over every calendar date of this interval.
DateInterval	toFlexInterval() Converts this fixed interval to a date interval with flexible boundaries which can participate in any kind of interval boundary manipulations.
<V> ValueInterval<PlainDate,T,V>	withValue(V value) Creates a combination of this interval with an associated value.

Method Detail

isFinite

public final boolean isFinite()

A calendar interval is always finite.

Specified by:

isFinite in interface ChronoInterval<PlainDate>

Returns:

true

isEmpty

public final boolean isEmpty()

A calendar interval is never empty.

Specified by:

isEmpty in interface ChronoInterval<PlainDate>

Returns:

false

contains

public boolean contains(ChronoInterval<PlainDate> other)

Description copied from interface: ChronoInterval

Does this interval contain the other one?

An interval cannot contain infinite intervals but can contain an empty interval if it contains the start anchor of the empty interval.

Specified by:

contains in interface ChronoInterval<PlainDate>

Parameters:

other - another interval whose relation to this interval is to be investigated

Returns:

true if this interval contains the other one else false

isBefore

public boolean isBefore(ChronoInterval<PlainDate> other)

Description copied from interface: ChronoInterval

Is this interval before the other one?

Specified by:

isBefore in interface ChronoInterval<PlainDate>

Parameters:

other - another interval whose relation to this interval is to be investigated

Returns:

true if this interval is before the other one else false

abuts

public boolean abuts(ChronoInterval<PlainDate> other)

Description copied from interface: ChronoInterval

Queries if this interval abuts the other one such that there is neither any overlap nor any gap between.

Note: Empty intervals never abut.

Specified by:

abuts in interface ChronoInterval<PlainDate>

Parameters:

other - another interval which might abut this interval

Returns:

true if there is no intersection and no gap between else false

isSimultaneous

public boolean isSimultaneous(T other)

Queries if this object and given object have the same position on the time axis.

Parameters:

other - object this instance is compared to

Returns:

true if this instance is temporally equal to other else false

toFlexInterval

public DateInterval toFlexInterval()

Converts this fixed interval to a date interval with flexible boundaries which can participate in any kind of interval boundary manipulations.

Returns:

DateInterval

streamDaily

public Stream<PlainDate> streamDaily()

Obtains a stream iterating over every calendar date of this interval.

Returns:

daily stream

withValue

public <V> ValueInterval<PlainDate,T,V> withValue(V value)

Creates a combination of this interval with an associated value.

Type Parameters:

V - generic value type

Parameters:

value - associated value, not null

Returns:

new value interval
