Global Binding Declarations

The code below shows the globalBindings declarations in po.xsd:

<jxb:globalBindings
        fixedAttributeAsConstantProperty="true"
        collectionType="java.util.Vector"
        typesafeEnumBase="xsd:NCName"
        choiceContentProperty="false"
        typesafeEnumMemberName="generateError"
        bindingStyle="elementBinding"
        enableFailFastCheck="false"
        generateIsSetMethod="false"
        underscoreBinding="asCharInWord"/>

In this example, all values are set to the defaults except for collectionType.

• Setting fixedAttributeAsConstantProperty to true indicates that all fixed attributes should be bound to Java constants. By default, fixed attributes are just mapped to either simple or collection property, whichever is more appropriate.

• Setting collectionType to java.util.Vector specifies that all lists in the generated implementation classes should be represented internally as vectors. Note that the class name you specify for collectionType must implement java.util.List and be callable by newInstance.

• If typesafeEnumBase is set to xsd:string, it would be a global way to specify that all simple type definitions deriving directly or indirectly from xsd:string and having enumeration facets should be bound by default to a typesafe enum. If typesafeEnumBase is set to an empty string, "", no simple type definitions would ever be bound to a typesafe enum class by default. The value of typesafeEnumBase can be any atomic simple type definition except xsd:boolean and both binary types.

• The JAXB implementation does not support the enableFailFastCheck attribute.

  Note –

  Using typesafe enum classes enables you to map schema enumeration values to Java constants, which in turn makes it possible to do compares on Java constants rather than string values.
