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.

ECIEncoderSet
public ECIEncoderSet(java.lang.String stringToEncode, java.nio.charset.Charset priorityCharset, int fnc1)
Constructs an encoder set- Parameters:
stringToEncode
- the string that needs to be encodedpriorityCharset
- The preferredCharset
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().
