Db.set_feedback

import com.sleepycat.db.*; public interface DbFeedback { public abstract void db_feedback(Db db, int opcode, int pct); } public class Db { public void set_feedback(DbFeedback db_feedback) throws DbException; ... } Description Some operations performed by the Berkeley DB library can take non-trivial amounts of time. The Db.set_feedback method can be used by applications to monitor progress within these operations. When an operation is likely to take a long time, Berkeley DB will call the specified callback method. This method must be declared with three arguments: the first will be a reference to the enclosing database handle, the second a flag value, and the third the percent of the operation that has been completed, specified as an integer value between 0 and 100. It is up to the callback method to display this information in an appropriate manner. The opcode argument may take on any of the following values: Db.DB_UPGRADE The underlying database is being upgraded. Db.DB_VERIFY The underlying database is being verified. The Db.set_feedback interface may be used to configure Berkeley DB at any time during the life of the application. The Db.set_feedback method throws an exception that encapsulates a non-zero error value on failure.
