Class Buffer

  • public final class Buffer
    extends java.lang.Object
    This is a wrapper around ByteBuffer. It maintains the same semantics and mechanisms of the ByteBuffer.

    Java 9 introduced API changes to some methods in ByteBuffer. Instead of returning instances of Buffer, those methods were rewritten to return instances of ByteBuffer instead. While this is perfectly fine at compile time, running "modern" code on Java 8 and earlier throws NoSuchMethodError. In order to prevent occurrences of this exceptions in the future, Buffer is used consistently in place of ByteBuffer. Since it is not possible to directly convert a Buffer into a ByteBuffer and the other way around, Buffer makes it less likely to develop dangerous code in the future.
