Definition

Namespace:
Java.Util
Assembly:
Mono.Android.dll

Overloads

Comparing(IFunction)
Obsolete.

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)
Obsolete.

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)

Caution

Use 'Java.Util.IComparator.Comparing'. This class will be removed in a future release.

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 ObsoleteAttribute

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.
