public interface PropertyReader
extends Serializable

Property reader. Object that implement this interface allow read-only access to a set of property entries. Each entry consists of a name and a value. Both are String objects.

Some implementations of this interface also support changing the underlying set of property entries. In this case, setting a property value to null has the same effect as removing the property altogether.

XINS 1.0.0
