Class StatementProxy

java.lang.Object

to.etc.dbpool.StatementProxy

All Implemented Interfaces:

AutoCloseable, Statement, Wrapper

Direct Known Subclasses:

PreparedStatementProxy

public class StatementProxy
extends Object
implements Statement

Encapsulates a java.sql.Statement for NEMA purposes. This class implements all of the Statement interfaces, and merely routes all calls to the original statement. The close() call is used to remove this from the connection's traced statement list.

Method Detail

close

public void close()
           throws SQLException

The original close is augmented with a call to remove this from the list of traced connection resources.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Statement

Throws:

SQLException

getRealConnection

public Connection getRealConnection()

_conn

protected ConnectionProxy _conn()

pool

protected ConnectionPool pool()

closedByConnection

public void closedByConnection()
                        throws SQLException

This gets called when the Connection was closed, and it closes the resources. This only closes the actual statement and does not remove the element from the connection's trace list.

Throws:

SQLException

appendQuery

protected void appendQuery(StringBuilder sb)

internalDumpInfo

protected void internalDumpInfo()

getSQL

public String getSQL()

Return the SQL string for this statement.

Returns:

wrap

protected SQLException wrap(SQLException x)

Base code to wrap exceptions if needed to provide a better message.

Parameters:

x -

Returns:

getRealStatement

public Statement getRealStatement()

Returns the real statement, or throws an error when the statement has been closed.
