Class ECIEncoderSet

  • public final class ECIEncoderSet
extends java.lang.Object
    Set of CharsetEncoders for a given input string Invariants: - The list contains only encoders from CharacterSetECI (list is shorter then the list of encoders available on the platform for which ECI values are defined). - The list contains encoders at least one encoder for every character in the input. - The first encoder in the list is always the ISO-8859-1 encoder even of no character in the input can be encoded by it. - If the input contains a character that is not in ISO-8859-1 then the last two entries in the list will be the UTF-8 encoder and the UTF-16BE encoder.

                     int fnc1)
        Constructs an encoder set
        Parameters:
        stringToEncode - the string that needs to be encoded
        priorityCharset - The preferred Charset or null.
        fnc1 - fnc1 denotes the character in the input that represents the FNC1 character or -1 for a non-GS1 bar code. When specified, it is considered an error to pass it as argument to the methods canEncode() or encode().
