Package com.fasterxml.jackson.dataformat.javaprop.io

Class Latin1Reader

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, java.lang.Readable
    public final class Latin1Reader
extends java.io.Reader
    Optimized Reader that reads ISO-8859-1 encoded content from an input stream. The reason for custom implementation is that this allows recycling of underlying read buffer, which is important for small content.
