isAfter

public boolean isAfter(EthiopianTime other)

Description copied from interface: Temporal

Queries if this object is after given object on a timeline.

Specified by:

isAfter in interface Temporal<EthiopianTime>

Parameters:

other - object this instance is compared to

Returns:

true if this instance is temporally after temporal else false

isBefore

public boolean isBefore(EthiopianTime other)

Description copied from interface: Temporal

Queries if this object is before given object on a timeline.

Specified by:

isBefore in interface Temporal<EthiopianTime>

Parameters:

other - object this instance is compared to

Returns:

true if this instance is temporally before temporal else false

isSimultaneous

public boolean isSimultaneous(EthiopianTime other)

Description copied from interface: Temporal

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

Is equivalent to !isAfter(temporal) && !isBefore(temporal). This method differs from the Object-method equals() such that first the comparison type must be a temporal one and second that only temporal-only state will be considered.

Specified by:

isSimultaneous in interface Temporal<EthiopianTime>

Parameters:

other - object this instance is compared to

Returns:

true if this instance is temporally equal to temporal else false

compareTo

public int compareTo(EthiopianTime other)

Description copied from class: TimePoint

Compares two time points preferably by their temporal positions on the common time axis.

Implementation note: In order to make the natural order consistent with equals() the whole state must be taken into account, with preference for those attributes which define the temporal position on the time axis.

Specified by:

compareTo in interface Comparable<EthiopianTime>

Specified by:

compareTo in class TimePoint<EthiopianTime.Unit,EthiopianTime>

See Also:

TimePoint.equals(Object)

equals

public boolean equals(Object obj)

Description copied from class: TimePoint

Compares the whole state of this instance with given object.

Implementations will usually define their state only based on the temporal position on the time axis because this is the most intuitive approach. Exceptions from this rule should be explicitly documented and reasoned.

Specified by:

equals in class TimePoint<EthiopianTime.Unit,EthiopianTime>

See Also:

TimePoint.compareTo(TimePoint)

hashCode

public int hashCode()

Description copied from class: TimePoint

Subclasses must redefine this method corresponding to the behaviour of equals().

Specified by:

hashCode in class TimePoint<EthiopianTime.Unit,EthiopianTime>

toString

public String toString()

Description copied from class: TimePoint

Provides a complete textual representation of the state of this time point.

The textual description often follows the conventions of ISO-8601. Usually the description starts with the chronological informations which are coarse-grained and ends with those ones which are fine-grained (for example the ISO-notation YYYY-MM-DD).

Specified by:

toString in class TimePoint<EthiopianTime.Unit,EthiopianTime>

toISO

public PlainTime toISO()

Converts this instance to its ISO-analogy.

Returns:

PlainTime

Since:

3.11/4.8

from

public static EthiopianTime from(PlainTime time)

Converts given ISO-time to Ethiopian time.

The special time 24:00 will be treated like 00:00. Fractions of second are lost during conversion.

Parameters:

time - ISO-time

Returns:

Ethiopian time

Since:

3.11/4.8

axis

public static TimeAxis<EthiopianTime.Unit,EthiopianTime> axis()

Provides a static access to the associated time axis respective chronology which contains the chronological rules.

Returns:

chronological system as time axis (never null)
