Method Detail

adjustIntoback to summary
public Temporal adjustInto(Temporal temporal)

Implements java.time.temporal.TemporalAdjuster.adjustInto.

Adjusts the specified temporal object to have this hour-minute. Note that if the target has a second or nanosecond field, that is not altered by this method.

This returns a temporal object of the same observable type as the input with the hour and minute changed to be the same as this.

The adjustment is equivalent to using Temporal#with(TemporalField, long) passing ChronoField#MINUTE_OF_DAY as the field. Note that this does not affect any second/nanosecond field in the target.

In most cases, it is clearer to reverse the calling pattern by using Temporal#with(TemporalAdjuster):

  // these two lines are equivalent, but the second approach is recommended
  temporal = thisHourMinute.adjustInto(temporal);
  temporal = temporal.with(thisHourMinute);

This instance is immutable and unaffected by this method call.

Parameters
temporal:Temporal

the target object to be adjusted, not null

Returns:Temporal

the adjusted object, not null

Annotations
@Override
Exceptions
DateTimeException:
if unable to make the adjustment

fromback to summary
public static HourMinute from(TemporalAccessor temporal)

Obtains an instance of HourMinute from a temporal object.

This obtains a hour-minute based on the specified temporal. A TemporalAccessor represents an arbitrary set of date and time information, which this factory converts to an instance of HourMinute.

The conversion extracts the HOUR_OF_DAY and MINUTE_OF_HOUR fields.

This method matches the signature of the functional interface TemporalQuery allowing it to be used in queries via method reference, HourMinute::from.

getback to summary
public int get(TemporalField field)

Overrides default java.time.temporal.TemporalAccessor.get.

Gets the value of the specified field from this hour-minute as an int.

This queries this hour-minute for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this hour-minute,. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.

Parameters

This checks if this hour-minute can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.

If the field is a ChronoField then the query is implemented here. The supported fields are:

  • MINUTE_OF_HOUR
  • MINUTE_OF_DAY
  • HOUR_OF_AMPM
  • CLOCK_HOUR_OF_AMPM
  • HOUR_OF_DAY
  • CLOCK_HOUR_OF_DAY
  • AMPM_OF_DAY
All other ChronoField instances will return false.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.

Parameters
field:TemporalField

Returns a copy of this hour-minute with the specified amount subtracted.

This returns a HourMinute based on this one, with the specified amount subtracted. The amount is typically Period but may be any other type implementing the TemporalAmount interface.

The calculation is delegated to the amount object by calling TemporalAmount#subtractFrom(Temporal). The amount implementation is free to implement the subtraction in any way it wishes, however it typically calls back to minus(long, TemporalUnit). Consult the documentation of the amount implementation to determine if it can be successfully subtracted.

This instance is immutable and unaffected by this method call.

queryback to summary
public <R> R query(TemporalQuery<R> query)

Overrides default java.time.temporal.TemporalAccessor.query.

Queries this hour-minute using the specified query.

This queries this hour-minute using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.

The result of this method is obtained by invoking the TemporalQuery#queryFrom(TemporalAccessor) method on the specified query passing this as the argument.

Parameters
<R>
the type of the result
query:TemporalQuery<R>

the query to invoke, not null

Returns:R

the query result, null may be returned (defined by the query)

rangeback to summary
public ValueRange range(TemporalField field)

Overrides default java.time.temporal.TemporalAccessor.range.

Gets the range of valid values for the specified field.

The range object expresses the minimum and maximum valid values for a field. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.

Parameters
field:TemporalField

the field to query the range for, not null

Returns:ValueRange

the range of valid values for the field, not null

Annotations
@Override
Exceptions
DateTimeException:
if the range for the field cannot be obtained
UnsupportedTemporalTypeException:

readResolveback to summary
private Object readResolve()

Validates the input.

Returns:Object

the valid object, not null

toLocalTimeback to summary
public LocalTime toLocalTime()

Returns the equivalent LocalTime.

This returns a LocalTime formed from this hour and minute.

Returns:LocalTime

the equivalent local time, not null

toStringback to summary
public String toString()

Overrides java.lang.Object.toString.

Outputs this hour-minute as a String, such as 12:31.

Returns:String

a string representation of this hour-minute, not null

@ToString
untilback to summary
public long until(Temporal endExclusive, TemporalUnit unit)

Implements java.time.temporal.Temporal.until.

Calculates the amount of time until another hour-minute in terms of the specified unit.

This calculates the amount of time between two HourMinute objects in terms of a single TemporalUnit. The start and end points are this and the specified hour-minute. The result will be negative if the end is before the start. The Temporal passed to this method is converted to a HourMinute using from(TemporalAccessor). For example, the period in hours between two hour-minutes can be calculated using startHourMinute.until(endHourMinute, YEARS).

The calculation is implemented in this method for ChronoUnit. The units MINUTES, HOURS and HALF_DAYS are supported. Other ChronoUnit values will throw an exception.

If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.

This instance is immutable and unaffected by this method call.

Parameters
endExclusive:Temporal

the end date, exclusive, which is converted to a HourMinute, not null

unit:TemporalUnit

the unit to measure the amount in, not null

Returns:long

the amount of time between this hour-minute and the end hour-minute

withback to summary
private HourMinute with(int newYear, int newMinute)

Returns a copy of this hour-minute with the new hour and minute, checking to see if a new object is in fact required.

Parameters
newYear:int

the hour to represent, validated from 0 to 23

newMinute:int

the minute-of-hour to represent, validated from 0 to 59

Returns:HourMinute

the hour-minute, not null

public HourMinute with(TemporalAdjuster adjuster)

Overrides default java.time.temporal.Temporal.with.

Returns an adjusted copy of this hour-minute.

This returns a HourMinute based on this one, with the hour-minute adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.

The result of this method is obtained by invoking the TemporalAdjuster#adjustInto(Temporal) method on the specified adjuster passing this as the argument.

This instance is immutable and unaffected by this method call.

Parameters
adjuster:TemporalAdjuster

the adjuster to use, not null

Returns:HourMinute

a HourMinute based on this with the adjustment made, not null

withback to summary
public HourMinute with(TemporalField field, long newValue)

Implements java.time.temporal.Temporal.with.

Returns a copy of this hour-minute with the specified field set to a new value.

This returns a HourMinute based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the hour or minute. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.

If the field is a ChronoField then the adjustment is implemented here. The supported fields behave as follows:

  • MINUTE_OF_HOUR - Returns a HourMinute with the specified minute-of-hour. The hour will be unchanged.
  • MINUTE_OF_DAY - Returns a HourMinute with the specified minute-of-day.
  • HOUR_OF_AMPM - Returns a HourMinute with the specified hour-of-am-pm. The AM/PM and minute-of-hour will be unchanged.
  • CLOCK_HOUR_OF_AMPM - Returns a HourMinute with the specified clock-hour-of-am-pm. The AM/PM and minute-of-hour will be unchanged.
  • HOUR_OF_DAY - Returns a HourMinute with the specified hour-of-day. The minute-of-hour will be unchanged.
  • CLOCK_HOUR_OF_DAY - Returns a HourMinute with the specified clock-hour-of-day. The minute-of-hour will be unchanged.
  • AMPM_OF_DAY - Returns a HourMinute with the specified AM/PM. The hour-of-am-pm and minute-of-hour will be unchanged.

In all cases, if the new value is outside the valid range of values for the field then a DateTimeException will be thrown.

All other ChronoField instances will throw an UnsupportedTemporalTypeException.

If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.

This instance is immutable and unaffected by this method call.

Parameters
field:TemporalField
