Examples of SerialClob

javax.sql.rowset.serial.SerialClob

A serialized mapping in the Java programming language of an SQL CLOB value.

The SerialClob class provides a constructor for creating an instance from a Clob object. Note that the Clob object should have brought the SQL CLOB value's data over to the client before a SerialClob object is constructed from it. The data of an SQL CLOB value can be materialized on the client as a stream of Unicode characters.

SerialClob methods make it possible to get a substring from a SerialClob object or to locate the start of a pattern of characters.

Thread safety

A SerialClob is not safe for use by multiple concurrent threads. If a SerialClob is to be used by more than one thread then access to the SerialClob should be controlled by appropriate synchronization. @author Jonathan Bruce
