Interface Interpreter

All Known Implementing Classes:

AsciiInterpreter, BCDInterpreter, EbcdicInterpreter, HEXInterpreter, LiteralInterpreter, SignedEbcdicNumberInterpreter

public interface Interpreter

Implementations convert Strings into byte arrays and vice versa.

Method Summary

Modifier and Type	Method and Description
int	getPackedLength(int nDataUnits) Returns the number of bytes required to interpret a String of length nDataUnits.
void	interpret(java.lang.String data, byte[] b, int offset) Converts the string data into a different interpretation.
java.lang.String	uninterpret(byte[] rawData, int offset, int length) Converts the byte array into a String.

Method Detail

interpret

void interpret(java.lang.String data,
               byte[] b,
               int offset)
        throws ISOException

Converts the string data into a different interpretation. Standard interpretations are ASCII, EBCDIC, BCD and LITERAL.

Throws:

ISOException - on error

uninterpret

java.lang.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 required to interpret a String of length nDataUnits.
