Method Summary

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

Method Detail

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 data to be interpreted.

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 required to interpret a String of length nDataUnits.
