Adds this period to the specified temporal object.
Adds this period to the specified temporal object.
This returns a temporal object of the same observable type as the input with this period added.
In most cases, it is clearer to reverse the calling pattern by using
Temporal#plus(TemporalAmount)
.
// these two lines are equivalent, but the second approach is recommended dateTime = thisPeriod.addTo(dateTime); dateTime = dateTime.plus(thisPeriod);
The specified temporal must have the same chronology as this period. This returns a temporal with the non-zero supported units added.
This instance is immutable and unaffected by this method call.

an object of the same type with the adjustment made, not null

DateTimeExceptionif unable to add
Checks if this period is equal to another period, including the chronology.
Checks if this period is equal to another period, including the chronology.
Compares this period with another ensuring that the type, each amount and the chronology are the same. Note that this means that a period of "15 Months" is not equal to a period of "1 Year and 3 Months".
the object to check, null returns false
true if this is equal to the other period
Gets the value of the requested unit.
Gets the value of the requested unit.
The supported units are chronology specific.
They will typically be ChronoUnit#YEARS YEARS
,
ChronoUnit#MONTHS MONTHS
and ChronoUnit#DAYS DAYS
.
Requesting an unsupported unit will throw an exception.

the long value of the unit

UnsupportedTemporalTypeExceptionif the unit is not supported
Gets the chronology that defines the meaning of the supported units.
Gets the chronology that defines the meaning of the supported units.
The period is defined by the chronology.
It controls the supported units and restricts addition/subtraction
to ChronoLocalDate
instances of the same chronology.
the chronology defining the period, not null
Gets the set of units supported by this period.
Gets the set of units supported by this period.
The supported units are chronology specific.
They will typically be ChronoUnit#YEARS YEARS
,
ChronoUnit#MONTHS MONTHS
and ChronoUnit#DAYS DAYS
.
They are returned in order from largest to smallest.
This set can be used in conjunction with #get(TemporalUnit)
to access the entire state of the period.

A hash code for this period.
A hash code for this period.
a suitable hash code
Checks if any of the supported units of this period are negative.
Checks if any of the supported units of this period are negative.
true if any unit of this period is negative
Checks if all the supported units of this period are zero.
Checks if all the supported units of this period are zero.
true if this period is zero-length
Returns a copy of this period with the specified period subtracted.
Returns a copy of this period with the specified period subtracted.
If the specified amount is a ChronoPeriod
then it must have
the same chronology as this period. Implementations may choose to
accept or reject other TemporalAmount
implementations.
This instance is immutable and unaffected by this method call.
the period to subtract, not null
a { @code ChronoPeriod} based on this period with the requested period subtracted, not null
if numeric overflow occurs
Returns a new instance with each amount in this period in this period multiplied by the specified scalar.
Returns a new instance with each amount in this period in this period multiplied by the specified scalar.
This returns a period with each supported unit individually multiplied. For example, a period of "2 years, -3 months and 4 days" multiplied by 3 will return "6 years, -9 months and 12 days". No normalization is performed.
the scalar to multiply by, not null
a { @code ChronoPeriod} based on this period with the amounts multiplied by the scalar, not null
if numeric overflow occurs
Returns a new instance with each amount in this period negated.
Returns a new instance with each amount in this period negated.
This returns a period with each supported unit individually negated. For example, a period of "2 years, -3 months and 4 days" will be negated to "-2 years, 3 months and -4 days". No normalization is performed.
a { @code ChronoPeriod} based on this period with the amounts negated, not null
if numeric overflow occurs, which only happens if one of the units has the value { @code Long.MIN_VALUE}
Returns a copy of this period with the amounts of each unit normalized.
Returns a copy of this period with the amounts of each unit normalized.
The process of normalization is specific to each calendar system. For example, in the ISO calendar system, the years and months are normalized but the days are not, such that "15 months" would be normalized to "1 year and 3 months".
This instance is immutable and unaffected by this method call.
a { @code ChronoPeriod} based on this period with the amounts of each unit normalized, not null
if numeric overflow occurs
Returns a copy of this period with the specified period added.
Returns a copy of this period with the specified period added.
If the specified amount is a ChronoPeriod
then it must have
the same chronology as this period. Implementations may choose to
accept or reject other TemporalAmount
implementations.
This instance is immutable and unaffected by this method call.
the period to add, not null
a { @code ChronoPeriod} based on this period with the requested period added, not null
if numeric overflow occurs
Subtracts this period from the specified temporal object.
Subtracts this period from the specified temporal object.
This returns a temporal object of the same observable type as the input with this period subtracted.
In most cases, it is clearer to reverse the calling pattern by using
Temporal#minus(TemporalAmount)
.
// these two lines are equivalent, but the second approach is recommended dateTime = thisPeriod.subtractFrom(dateTime); dateTime = dateTime.minus(thisPeriod);
The specified temporal must have the same chronology as this period. This returns a temporal with the non-zero supported units subtracted.
This instance is immutable and unaffected by this method call.
the temporal object to adjust, not null
an object of the same type with the adjustment made, not null
