public Class Buffers

extends Object
Class Inheritance
Imports
java.nio.Buffer
Utility functions to help avoid binary incompatibility due to variadic return types on Java 9. Java 9 introduced new overloads of several Buffer methods on its subclasses. Because those methods return the actual type of the subclass, they are incompatible with Java 8 where no such overloads exist. This utility casts all buffers to Buffer and makes the call from there, avoiding binding directly to the overloads that don't exist on Java 8.
