java.lang.Object org.jibx.extras.HashMapperStringToSchemaType
public class HashMapperStringToSchemaType
Custom marshaller/unmarshaller for java.util.Map
instances. This handles mapping hash maps with string keys and values that
match basic schema datatypes to and from XML. The key objects are marshalled
as simple text values, using the toString()
method to convert
them to String
if they are not already of that type. When
unmarshalling the keys are always treated as String
values. The
corresponding values can be any of the object types corresponding to basic
schema data types, and are marshalled with xsi:type attributes to specify the
type of each value. The types currently supported are Byte
,
Double
, Float
, Integer
,
Long
, java.util.Date
(as xsd:dateTime),
java.sql.Date
(as xsd:date), java.sql.Time
(as
xsd:time), java.math.BigDecimal
(with no exponent allowed, as
xsd:decimal), and java.math.BigInteger
(as xsd:integer). The
xsd:type attribute is checked when unmarshalling values to select the proper
deserialization and value type. The name of the top-level element in the XML
structure can be configured in the binding definition, but the rest of the
names are predefined and set in the code (though the namespace configured for
the top-level element will be used with all the names).
The net effect is that the XML structure will always be of the form:
<map-name size="6" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <entry key="name" xsi:type="xsd:string">John Smith</entry> <entry key="street" xsi:type="xsd:string">12345 Happy Lane</entry> <entry key="city" xsi:type="xsd:string">Plunk</entry> <entry key="state" xsi:type="xsd:string">WA</entry> <entry key="rating" xsi:type="xsd:int">6</entry> <entry key="joined" xsi:type="xsd:dateTime">2002-08-06T00:13:31Z</entry> </map-name>
where "map-name" is the configured top-level element name, the "size" attribute is the number of pairs in the hash map, and the "entry" elements are the actual entries in the hash map.
For unmarshalling this requires an active namespace declaration with a prefix for the schema namespace. All xsi:type attribute values must use this prefix. If more than one prefix is declared for the schema namespace, the innermost one declared must be used.
