Examples of org.apache.jdo.model.java.JavaType

org.apache.jdo.model.java.JavaType
A JavaType instance represents a type as defined in the Java language. The interface defines interrogative methods to check whether a type is primitive, an interface or array, is a JDO supported collection or map, is a value or trackable class, is a persistence capable class, etc. Furthermore it defines methods to get detailed information about the type such as name, modifiers, superclass and the JDO meta data if this type represent a persistence capable class.
Different environments (runtime, enhancer, development) will have different JavaType implementations to provide answers to the various methods. @author Michael Bouschen @since JDO 1.0.1

        // return true if obj is this
        if (obj == this) return  true;
        // return false if obj does not have the correct type
        if ((obj == null) || !(obj instanceof JavaType)) return false;


        JavaType other = (JavaType)obj;
        // compare names
        String name = getName();
        if (name == null) return other.getName() == null;
        return name.equals(other.getName());
