    • getConsoleEncoding

      public org.jcodings.Encoding getConsoleEncoding()
      Since Java 1.6, class Console is available. But the encoding or codepage of the underlying connected console is currently private. Had to use Reflection to get it.
      Returns:
      console codepage

    • findEncoding

      public org.jcodings.Encoding findEncoding(IRubyObject str)
      Find an encoding given a Ruby object, coercing it to a String in the process.
      Parameters:
      str - the object to coerce and use to look up encoding. The coerced String must be ASCII-compatible.
      Returns:
      the Encoding object found, nil (for internal), or raises ArgumentError

    • findEncodingNoError

      public org.jcodings.Encoding findEncodingNoError(IRubyObject str)
      Find an encoding given a Ruby object, coercing it to a String in the process. This version does not raise a Ruby error if it can't find the encoding, and simply returns null.
      Parameters:
      str - the object to coerce and use to look up encoding. The coerced String must be ASCII-compatible.
      Returns:
      the Encoding object found, nil (for internal)

      private org.jcodings.Encoding findEncodingCommon(ByteList name, boolean error)

    • findEntry

      public org.jcodings.EncodingDB.Entry findEntry(IRubyObject str)
      Find an encoding given a Ruby object, coercing it to a String in the process.
      Parameters:
      str - the object to coerce and use to look up encoding. The coerced String must be ASCII-compatible.
      Returns:
      the Encoding object found, nil (for internal), or raises ArgumentError

      public Charset charsetForEncoding(org.jcodings.Encoding encoding)
      Get a java.nio Charset for the given encoding, or null if impossible
      Parameters:
      encoding - the encoding
      Returns:
      the charset
