Class SignedEbcdicNumberInterpreter

java.lang.Object
  org.jpos.iso.SignedEbcdicNumberInterpreter

All Implemented Interfaces:

Interpreter

public class SignedEbcdicNumberInterpreter
extends Object
implements Interpreter

Implements EBCDIC Interpreter for signed numerics. (see http://publib.boulder.ibm.com/infocenter/wmbhelp/v6r0m0/index.jsp?topic=/com.ibm.etools.mft.doc/ad06900_.htm) Strings are converted to and from EBCDIC bytes. Negatives will be prepended with "-" Unsigned numbers are interpreted as positive

Field Detail

INSTANCE

public static final SignedEbcdicNumberInterpreter INSTANCE

An instance of this Interpreter. Only one needed for the whole system

public SignedEbcdicNumberInterpreter()

Method Detail

interpret

public void interpret(String data,
                      byte[] targetArray,
                      int offset)

Description copied from interface: Interpreter

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

Specified by:

interpret in interface Interpreter

Parameters:

data - The data to be interpreted.

uninterpret

public String uninterpret(byte[] rawData,
                          int offset,
                          int length)

Description copied from interface: Interpreter

Converts the byte array into a String. This reverses the interpret method.

Specified by:

uninterpret in interface Interpreter

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

public int getPackedLength(int nDataUnits)

Description copied from interface: Interpreter

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

Specified by:

getPackedLength in interface Interpreter
