Method Summary

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)

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

Parameters:

data - The data to be interpreted.

uninterpret

java.lang.String uninterpret(byte[] rawData,
                             int offset,
                             int length)

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.

getPackedLength

int getPackedLength(int nDataUnits)

Returns the number of bytes required to interpret a String of length nDataUnits.
