| Search criteria are expressed as a tree of search-terms, forming
a parse-tree for the search expression.
Search-terms are represented by this class. This is an abstract
class; subclasses implement specific match methods.
Search terms are serializable, which allows storing a search term
between sessions.
Warning:
Serialized objects of this class may not be compatible with future
JavaMail API releases. The current serialization support is
appropriate for short term storage.
Warning:
Search terms that include references to objects of type
Message.RecipientType will not be deserialized
correctly on JDK 1.1 systems. While these objects will be deserialized
without throwing any exceptions, the resulting objects violate the
type-safe enum contract of the Message.RecipientType
class. Proper deserialization of these objects depends on support
for the readReplace method, added in JDK 1.2. |
