There are cases in which a simple XML data type must be mapped to the
corresponding Java wrapper class for the Java primitive type:
v an element declaration with the nillable attribute set to True
v an element declaration with the minOccurs attribute set to 0 (zero) and the
v an attribute declaration with the use attribute set to optional or absent and
The following shows examples of each:
v
v
v
The element/attribute declarations for code, code2, code3 above are all mapped to
the java.lang.Integer type.
JavaBean Metadata ASI format: The metadata is derived mostly from the structure of
the bean. Other metadata, such as containedType and maxLength are not normal
parts of a JavaBean structure, so they must be part of the annotation maps.
Annotation maps:
Annotations are not normally part of a JavaBean structure, so JavaBeanRecords
must contain annotations in a specific format to be usable by the metadata API.
The JavaBeanRecord must implement the BeanMetadata interface.
public interface BeanMetadata {
}
Each property (if it needs metadata) will have its own Map, which will be stored
in the propertyAnnotations map, using the property name as key.
Reserved keys in the propertyAnnotations map:
v ContainedType
v PrimaryKey:
v DefaultValue:
v MaxLength:
