I'm using an external bindings file when using jaxb against an XML schema.
I'm mostly using the bindings file to map from the XML schema primitives to my own types.
This is a snippet of the bindings file
<jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:ai="http://java.sun.com/xml/ns/jaxb/xjc" extensionBindingPrefixes="ai">
<jxb:bindings schemaLocation="xsdurl" node="xs:schema">
<jxb:globalBindings>
<jxb:javaType name="com.companyname.StringType" xmlType="xs:string"
parseMethod="parse" printMethod="print" hasNsContext="true">
</jxb:javaType>
</jxb:globalBindings>
</jxb:bindings>
</jxb:bindings>
So whenever a xs:string
is encountered, the com.companyname.StringType
the methods print
/ parse
are called for marshalling/unmarshalling etc.
Now if JAXB encounters an xs:enumeration
it will generate a java enum
.
For example:
<xs:simpleType name="Address">
<xs:restriction base="xs:string">
<xs:enumeration value="ADDR"/>
<xs:enumeration value="PBOX"/>
</xs:restriction>
</xs:simpleType>
public enum Address
{
ADDR,
PBOX,
public String value() {
return name();
}
public static Address fromValue(String v) {
return valueOf(v);
}
}
Does anyone know if it is possible to customise the creation of an enum
like it is for a primitive? I would like to be able to:
Add a standard member variable / other methods to every enum generated by jaxb.
Specify the static method used to create the
enum
.
