Comparing(IFunction)

Accepts a function that extracts a java.lang.Comparable Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.
Comparing(IFunction, IComparator)

Accepts a function that extracts a sort key from a type T, and returns a Comparator<T> that compares by that sort key using the specified Comparator.

Comparing(IFunction)

Accepts a function that extracts a java.lang.Comparable Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.

Parameters

keyExtractor
IFunction

the function used to extract the Comparable sort key

Returns

IComparator

a comparator that compares by an extracted key

Attributes
RegisterAttribute JavaTypeParametersAttribute

Remarks

Accepts a function that extracts a java.lang.Comparable Comparable sort key from a type T, and returns a Comparator<T> that compares by that sort key.

The returned comparator is serializable if the specified function is also serializable.
