Performance – Arrays

ArrayNew ( dimension); arrayNew (1);




application.arts = arts;

ArrayNew(dimension, synchronized) arrayNew (1, false);




application.arts = arts;

ArrayNew(dimension, synchronized) arrayNew (1, false);

Safe Navigation



Cleaner Code

x = getX();

y = x.getY();


Cleaner Code

x = getX();if( isDefined(“x”) )

y = x.getY();


Cleaner Code – Safe navigation

x = getX();if( isDefined(“x”) )

y = x.getY();

VS

x = getX();y=x?.getY();


Cleaner Code

x = getX();if( isDefined(“x”) ){

y = x.getY();if( isDefined(“y”) ){

z = y.getZ();if( isDefined(“z”) )

myData = z.getData();}

}


Cleaner Code

x = getX();if( isDefined(“x”) ){

y = x.getY();if( isDefined(“y”) ){

z = y.getZ();if( isDefined(“z”) )

myData = z.getData();}

}

myData = x?.getY()?.getZ()?.getData();


Cleaner Code – stored procedures

<CFSTOREDPROC PROCEDURE=“testProcedure"datasource=“testDatasource"><CFPROCPARAM type="In" cfsqltype="CF_SQL_VARCHAR" value="ONE"

> <CFPROCPARAM type="In" cfsqltype="CF_SQL_VARCHAR" value="TWO"

></CFSTOREDPROC>


Cleaner Code – dbvarname

<CFSTOREDPROC PROCEDURE=“testProcedure"datasource=“testDatasource"><CFPROCPARAM type="In" cfsqltype="CF_SQL_VARCHAR" value="ONE"

dbvarname="@p_VarName1"> <CFPROCPARAM type="In" cfsqltype="CF_SQL_VARCHAR" value="TWO" dbvarname="@p_VarName2">

</CFSTOREDPROC>
