pack-priv Class InstantComparator

extends Object
implements Comparator<Instant>
Class Inheritance
All Implemented Interfaces
java.util.Comparator
Imports
java.time.Instant, java.util.Comparator
Specialized comparator for Instants. If either timestamp has a zero fraction, compares only seconds. If either timestamp has no time fraction smaller than a millisecond, compares only milliseconds. If either timestamp has no fraction smaller than a microsecond, compares only microseconds.

a value < 0 if a < b, a value > 0 if a > b, and 0 if a == b
compare(Instant
first Instant to compare

public int compare(Instant a, Instant b)

Implements java.util.Comparator.compare.

Doc from java.util.Comparator.compare.

Compares its two arguments for order. Returns a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

The implementor must ensure that signum(compare(x, y)) == -signum(compare(y, x)) for all x and y. (This implies that compare(x, y) must throw an exception if and only if compare(y, x) throws an exception.)

The implementor must also ensure that the relation is transitive: ((compare(x, y)>0) && (compare(y, z)>0)) implies compare(x, z)>0.

Finally, the implementor must ensure that compare(x, y)==0 implies that signum(compare(x, z))==signum(compare(y, z)) for all z.

Parameters
a:Instant

the first object to be compared.

b:Instant

the second object to be compared.

Returns:int

a negative integer, zero, or a positive integer as the first argument is less than, equal to, or greater than the second.

Annotations

compareback to summary
public int compare(Instant a, Instant b, boolean forceSecondsOnly)

Compares two Instants to the lower resolution of the two instants. See InstantComparator.

Parameters
a:Instant

first Instant to compare

b:Instant

second Instant to compare

forceSecondsOnly:boolean

whether to omit all fraction comparison

Returns:int

a value < 0 if a < b, a value > 0 if a > b, and 0 if a == b
