This package provides classes to parse and model every possible field and letter option of a SWIFT MT message.

The constructor accepts the field string literal and parses its content into a list of String with a simple and generic API of getComponent1() ... getComponentN(). If the component represents a date or number, additional API is provided to get the component parsed into a Calendar and Number with methods like getComponent1AsCalendar() and getComponent3AsNumber().

To best usage scenario for this functionality is to read and process received SWIFT messages, when you have a FIN message parsed into a SwiftMessage object and you need to retrieve specific fields' components.

Simple usage example:

Field32A f = new Field32A("090801USD1234,56");
String sdate = f.getComponent1()); //"090801";
Calendar date = f.getComponent1AsCalendar();
BigDecimal number = new BigDecimal(f.getComponent3AsNumber().doubleValue());

Full parsing example:

String fin = "{1:F01BANKDEFMAXXX2039063581}"+
"{2:O1031609050901BANKDEFXAXXX89549829458949811609N}"+
"{3:{108:00750532785315}}{4:\n"+
":20:007505327853\n"+
":23B:CRED\n"+
":32A:050902JPY3520000,\n"+
":33B:JPY3520000,\n"+
":50K:EUROXXXEI\n"+
":52A:FEBXXXM1\n"+
":53A:MHCXXXJT\n"+
":54A:FOOBICXX\n"+
":59:/13212312\n"+
"RECEIVER NAME S.A\n"+
":70:FUTURES\n"+
":71A:SHA\n"+
":71F:EUR12,00\n"+
":71F:EUR2,34\n"+
"-}";
SwiftMessage m = (new ConversionService()).getMessageFromFIN(fin);

Field32A f = new Field32A(m.getBlock4().getTagValue("32A"));

assertEquals("010203", f.getComponent1());
assertEquals(2001, f.getComponent1AsCalendar().get(Calendar.YEAR));
assertEquals(1, f.getComponent1AsCalendar().get(Calendar.MONTH));
assertEquals(3, f.getComponent1AsCalendar().get(Calendar.DATE));
assertEquals("USD", f.getComponent2());
assertEquals(new BigDecimal(123.45), 
    new BigDecimal(f.getComponent3AsNumber().doubleValue()));
