[ http://issues.apache.org/jira/browse/DERBY-983?page=comments#action_12366483 ]
Daniel John Debrunner commented on DERBY-983: --------------------------------------------- Shorthand methods can also decrease the size of the class, usually you are replacing a common expression or sequence with a simpler one. So every time the method is used there is a less number of instructions, this has to be balanced against the increased size of the class due to the method. If the shorthand method is shared across classes then the potential for space savings increase. Also they can be providing an encapsulation purpose, ensuring logic is only written once, so when it needs to change it's changed correctly in one place, rather than incorrectly by the coder missing one spot. Take the issue in the embedded driver where Util.notImplemented() is possibly being replaced with InternalDriver.getSQLExceptionFactory().notImplemented(). Apart from adding code here through an extra method call to each caller, the class has also gained a new constant pool entries such as the class name for SQLExceptionFactory, the method name getSQLExceptionFactory, the method descriptor for getSQLExceptionFactory. All leading to an increase in size. > NetClient JDBC (40) using engine classes > ---------------------------------------- > > Key: DERBY-983 > URL: http://issues.apache.org/jira/browse/DERBY-983 > Project: Derby > Type: Bug > Components: Network Client > Environment: all > Reporter: Anurag Shekhar > Assignee: Anurag Shekhar > Attachments: derby-983.diff > > network client has refrence of > org.apache.derby.impl.jdbc.Util.notImplemented () > this will cause class not found exception as this class is not part of client > jar -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
