As shown above, the XSDateTime interface provides mapping to a number of decimal/integer data types. The application needs to ensure that appropriate methods for each of these types is invoked. The mapping of these types to defined methods is shown in the table below. Accessing methods that are undefined for a type will give unexpected results.
| XML Schema Data Type | Applicable method in XSDateTime* |
| integer | getBigInteger() |
| positiveInteger | getBigInteger() |
| negativeInteger | getBigInteger() |
| nonPositiveInteger | getBigInteger() |
| nonNegativeInteger | getBigInteger() |
| unsignedShort | getInt() |
| unsignedLong | getBigInteger() |
| unsignedByte | getShort() |
| unsignedInt | getLong() |
| long | getLong() |
| int | getInt() |
| short | getShort() |
| byte | getByte() |
* This
shows the base method that can be called. That is, users can call this
method and all methods returning bigger types than the base method
according to the order: byte < short < int < long <
BigInteger < BigDecimal. For example, in the case of unsignedShort,
users can call getInt(), getLong(), getBigInteger() and getBigDecimal()
but NOT getShort() or getByte().
