All Known Implementing Classes:
AsciiInterpreter, BCDInterpreter, EbcdicInterpreter, HEXInterpreter, LiteralInterpreter, SignedEbcdicNumberInterpreter
public interface Interpreter
Implementations convert Strings into byte arrays and vice versa.

    Modifier and Type
    Method
    Description
    int
    getPackedLength(int nDataUnits)
    Returns the number of bytes needed to store nDataUnits data units in this interpretation.
    void

  • Method Details

    • interpret

      void interpret(String data, byte[] b, int offset) throws ISOException
      Converts the string data into a different interpretation. Standard interpretations are ASCII, EBCDIC, BCD and LITERAL.
      Parameters:
      data - the string data to interpret
      b - the target byte array
      offset - the offset in b to start writing at
      Throws:
      ISOException - on error

    • uninterpret

      String uninterpret(byte[] rawData, int offset, int length) throws ISOException
      Converts the byte array into a String. This reverses the interpret method.
      Parameters:
      rawData - The interpreted data.
      offset - The index in rawData to start interpreting at.
      length - The number of data units to interpret.
      Returns:
      The uninterpreted data.
      Throws:
      ISOException - on error

    • getPackedLength

      int getPackedLength(int nDataUnits)
      Returns the number of bytes needed to store nDataUnits data units in this interpretation.
      Parameters:
      nDataUnits - the number of logical data units
      Returns:
      the packed byte length
