Constructor Detail

ISOBinaryFieldPackager

public ISOBinaryFieldPackager()

Constructs a default ISOBinaryFieldPackager. There is no length prefix and a literal interpretation. The set methods must be called to make this ISOBinaryFieldPackager useful.

ISOBinaryFieldPackager

public ISOBinaryFieldPackager(int maxLength,
                              java.lang.String description,
                              BinaryInterpreter interpreter,
                              Prefixer prefixer)

Creates an ISOBinaryFieldPackager.

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.

interpreter - The interpreter used to encode the field.

prefixer - The type of length prefixer used to encode this field.

ISOBinaryFieldPackager

public ISOBinaryFieldPackager(BinaryInterpreter interpreter,
                              Prefixer prefixer)

Creates an ISOBinaryFieldPackager.

Parameters:

interpreter - The interpreter used to encode the field.

prefixer - The type of length prefixer used to encode this field.
