ISOAmountFieldPackager
public ISOAmountFieldPackager(int maxLength, java.lang.String description, Padder padder, Interpreter interpreter, Prefixer prefixer)
Creates an ISOAmountFieldPackager.- Parameters:
maxLength
- The maximum length of the field in characters or bytes depending on the datatype.description
- The description of the field. For human readable output.padder
- The type of padding used.interpreter
- The interpreter used to encode the field.prefixer
- The type of length prefixer used to encode this field.
-
ISOAmountFieldPackager
public ISOAmountFieldPackager()
Constructs a default ISOAmountFieldPackager. There is no padding, no length prefix and a literal interpretation. The set methods must be called to make this ISOAmountFieldPackager useful.
-
ISOAmountFieldPackager
public ISOAmountFieldPackager(Padder padder, Interpreter interpreter, Prefixer prefixer)
Constructs an ISOAmountFieldPackager with a specific Padder, Interpreter and Prefixer. The length and description should be set with setLength() and setDescription methods.- Parameters:
padder
- The type of padding used.interpreter
- The interpreter used to encode the field.prefixer
- The type of length prefixer used to encode this field.
-
-
Method Detail
-
setPadder
public void setPadder(Padder padder)
Sets the Padder.- Parameters:
padder
- The padder to use during packing and unpacking.
-
setInterpreter
public void setInterpreter(Interpreter interpreter)
Sets the Interpreter.- Parameters:
interpreter
- The interpreter to use in packing and unpacking.
-
setPrefixer
public void setPrefixer(Prefixer prefixer)
Sets the length prefixer.- Parameters:
prefixer
- The length prefixer to use during packing and unpacking.
-
getMaxPackedLength
public int getMaxPackedLength()
Returns the prefixer's packed length and the interpreter's packed length.- Specified by:
getMaxPackedLength
in classISOFieldPackager
-
pack
public byte[] pack(ISOComponent c) throws ISOException
Packs the component into a byte[].- Specified by:
pack
in classISOFieldPackager
- Parameters:
c
- - a component- Returns:
- packed component
- Throws:
ISOException
-
unpack
public int unpack(ISOComponent c, byte[] b, int offset) throws ISOException
Unpacks the byte array into the component.- Specified by:
unpack
in classISOFieldPackager
- Parameters:
c
- The component to unpack into.b
- The byte array to unpack.offset
- The index in the byte array to start unpacking from.- Returns:
- The number of bytes consumed unpacking the component.

ISOException
-
unpack
public void unpack(ISOComponent c, java.io.InputStream in) throws java.io.IOException, ISOException
Unpack the input stream into the component.- Overrides:
unpack
in classISOFieldPackager
- Parameters:
c
- The Component to unpack into.in
- Input stream where the packed bytes come from.- Throws:
java.io.IOException
- Thrown if there's a problem reading the input stream.ISOException
-
checkLength
protected void checkLength(int len, int maxLength) throws java.lang.IllegalArgumentException
Checks the length of the data against the maximum, and throws an IllegalArgumentException. This is designed to be called from field Packager constructors and the setLength() method.- Parameters:
len
- The length of the data for this field packager.maxLength
- The maximum length allowed for this type of field packager. This depends on the prefixer that is used.- Throws:
java.lang.IllegalArgumentException
- If len > maxLength.
