Constructors Summary
public SimpleListDeserializer(Class javaType, QName xmlType)
The Deserializer is constructed with the xmlType and javaType (which could be a java primitive like int.class)

                          
         
        super (javaType, xmlType);

        this.xmlType = xmlType;
        this.javaType = javaType;
public SimpleListDeserializer(Class javaType, QName xmlType, org.apache.axis.description.TypeDesc typeDesc)

        super (javaType, xmlType, typeDesc);

        this.xmlType = xmlType;
        this.javaType = javaType;
        this.typeDesc = typeDesc;
Methods Summary

Convert the string that has been accumulated into an Object. Subclasses may override this.

Set the bean properties that correspond to element attributes. This method is invoked after startElement when the element requires deserialization (i.e. the element is not an href and the value is not nil.)

param
namespace is the namespace of the element
