Class LogicalPreparedStatement

java.lang.Object
  org.apache.derby.client.am.LogicalStatementEntity
      org.apache.derby.client.am.LogicalPreparedStatement

All Implemented Interfaces:: java.sql.PreparedStatement, java.sql.Statement, java.sql.Wrapper

Direct Known Subclasses:: LogicalCallableStatement, LogicalPreparedStatement40

public class LogicalPreparedStatement
extends LogicalStatementEntity
implements java.sql.PreparedStatement
extends LogicalStatementEntity
implements java.sql.PreparedStatement

A wrapper class for a physical Derby prepared statement.

The idea behind the logical prepared statement is to allow reuse of the physical prepared statement. In general the logical entity will forward all calls to the physical entity. A few methods have special implementations, the most important one being LogicalStatementEntity.close(). Each method will check that the logical statement is still open before the call is forwarded to the underlying physical statement.
