Dibyendu Majumdar updated DERBY-3451:
-------------------------------------
Description:
In the package org.apache.derby.iapi.error, the class StandardException
contains references to following classes:
org.apache.derby.impl.jdbc.Util
org.apache.derby.impl.jdbc.EmbedSQLException
This is undesirable as it introduces a dependency between StandardException and
the implementation of EmbedSQLException.
was:
In the package org.apache.derby.iapi.error, the class StandardException
contains references to following classes:
org.apache.derby.impl.jdbc.Util
org.apache.derby.impl.jdbc.EmbedSQLException
This is undesirable as it introduces a dependency between StandardException and
the implementation of EmbedSQLException.
To remove this dependency, following changes have been made.
A new interface called DerbySQLException has been added to
org.apache.derby.iapi.error.
The EmbedSQLException class has been modified to implement this interface.
The StandardException calls the isSimpleWrapper method on the DerbySQLException
interface, thereby avoiding a need to reference EmbedSQLException.
A new static method getArgumentFerry() has been added to StandardExcepion. This
performs the same task as the current getArgumentFerry() method in
SQLExceptionFactory and SQLExceptionFactory40.
SQLExceptionFactory.getArgumentFerry() has been amended to call
StandardException.getArgumentFerry().
SQLExceptionFactory40.getArgumentFerry() has been removed.
StandardException.getArgumentFerry() now handles the pre-JDBC3 and post-JDBC4
scenarios (in the pre-JDBC4 scenario, the passed argument is a
DerbySQLException, which is returned immediately), so there is no need to
override this functionality.
This change allows us to avoid having a dependency between StandardException
and Util.
As the getArgumentFerry() method now checks for DerbySQLException rather than
EmbedSQLException, it is able to avoid dependency on EmbedSQLException.
