Class DataFormatter

java.lang.Object

ifs.fnd.buffer.DataFormatter

All Implemented Interfaces:

java.lang.Cloneable

Direct Known Subclasses:

BooleanFormatter, DateFormatter, NumberFormatter, StringFormatter

public abstract class DataFormatter
extends java.lang.Object
implements java.lang.Cloneable

Transforms a simple Java Object (like Date, Double, String or Boolean) into a String and vice versa. This class defines the following data types (base-types and sub-types):

   Type Name   Type ID    Base Type Marker
   ---------   ---------- ----------------
   String      STRING            S
   Number      NUMBER            N
   Integer     INTEGER
   Money       MONEY
   Datetime    DATETIME          D
   Date        DATE
   Time        TIME
   Boolean     BOOLEAN           B

An instance of DataFormatter works with only one Type ID, which is specified at the construction time and is returned by getTypeId() method.
