Class ByteArrayCharSequence

  • All Implemented Interfaces:
    java.lang.CharSequence
    public class ByteArrayCharSequence
extends java.lang.Object
implements java.lang.CharSequence
    A CharSequence view onto a byte array of UTF-8-encoded characters, with the proviso that all of the characters were encoded as a single byte in UTF-8. This uses Java's built-in casting from UTF-8 to char primitives.

      • toSingleByteUtf8Encoding

        public static byte[] toSingleByteUtf8Encoding​(java.lang.CharSequence charSequence)
        Encodes a given CharSequence into a byte[] in UTF-8 encoding, with the requirement that it must be possible to represent all characters as a single byte in UTF-8. Otherwise an exception will be thrown.
        Parameters:
        charSequence - The CharSequence to encode
        Returns:
        A new byte[] encoding characters from the given CharSequence in UTF-8
        Throws:
        java.lang.IllegalStateException - If the characters cannot be encoded as described
