Class CharPredicates

java.lang.Object

com.github.tommyettinger.ds.support.util.CharPredicates

public final class CharPredicates
extends Object

Predefined CharPredicate tests that will work identically on all target platforms. These are meant to replace Character's static methods that test char properties, but may do so differently on different JRE versions (due to newer Unicode versions and their changes) or on GWT (where Unicode properties are essentially missing). This is not directly included elsewhere in this library to best allow dead code elimination.
This is currently compatible with OpenJDK 25's Character methods.
