## Class FBCachedClob

- java.lang.Object
- - org.firebirdsql.jdbc.field.FBCachedClob

- All Implemented Interfaces:
    java.sql.Clob, java.sql.NClob

      public class FBCachedClob
      extends java.lang.Object
      implements java.sql.Clob, java.sql.NClob

  Clob implementation that is cached client-side.

  This implementation is used for disconnected result sets (ie scrollable and hold cursors over commit).

  This class also implements `NClob` so it can be used with the `set/get/updateNClob` methods transparently. It technically does not conform to the JDBC requirements for `NClob`.
