  @Jon, I'm not sure you'd actually see any real performance gain by using a StringBuffer for 50 words, as you have the overhead of instantiating the Java object first. Definitely worthwhile for longer strings.... read more »

  @Ben, I thought it would be fun to try :) Java arrays and CF arrays aren't the same which makes it harder than it should be. You can also use the copyOfRange method to get something like the first 10 and last 10 words of an article like this: <cfset javaArray = CreateObject( "java","java.util.Ar... read more »

  Just for fun you could do this... <cfset javaArray = CreateObject( "java","java.util.Arrays" ) /> <cfset wordArray = javaArray.copyOf( blogContent.Split( " " ), 50 ) /> <cfset blogSnippet = ArrayToList( wordArray, " " ) /> <p>#blogSnippet#</p>... read more »

• Learning ColdFusion 9: Trying To Understand ORM Event Handling

  Posted on Aug 24, 2009 at 11:59 AM

  @Ben, Another great post! I'll have a guess that the update events are not fired until they are actually updated at the end of the request. You could try forcing it by adding an ORMFlush() after the entity save and before the cfdump. @Rick, you can use this for logging to a file (audit trail) or fo... read more »

• Learning ColdFusion 9: EntityNew() vs. The NEW Operator / CreateObject()

  @Ben, @Rupesh In that case I apologise for posting incorrect information. I was under the impression that hibernate was being used. Sorry guys!... read more »

• Learning ColdFusion 9: EntityNew() vs. The NEW Operator / CreateObject()

  Posted on Aug 20, 2009 at 10:58 AM

  @Rob, I've played around with the hibernate inheritance and find that it works really well. The method I prefer is the one-table-per-entity and the discriminator column. For example for a user superclass, with a manager subclass my code would be something like this: /** * @output false * @hint I ... read more »

• Learning ColdFusion 9: EntityNew() vs. The NEW Operator / CreateObject()

  Posted on Aug 20, 2009 at 10:50 AM

  I think I'm right in saying that EntityNew uses Hibernate directly to create the entity, so it has Java performance. Whereas using new has the performance impact of ColdFusion creating the object. I like using the two methods so that I can see in my code if I'm working with a persisted entity of a... read more »

  Hi Ben, that is a great point that Bob raised about letting an entity validate itself. I had a look into and my response was too long to add here so I posted it here: http://www.aliaspooryorik.com/blog/index.cfm/e/posts.details/post/cf9-orm-clearing-the-session-cache-227... read more »

• My 1,000th ColdFusion Post - What It Means To Me (And Free Prizes)

  Posted on Jan 23, 2009 at 12:55 PM

  Congratulations and Thank You Ben for all your posts! I started out with ColdFusion because when I was walking down the road in my lunch break I saw an ad in a window for a web developer and it was a CF shop. Since then I've built applications in ASP, .Net & PHP and can honestly say that ColdFusio... read more »

• Ask Ben: Dynamic Table Names In ColdFusion Queries

  Posted on Nov 13, 2008 at 11:01 AM

  @Ben - it's certainly easier to read! I really hope CF9 supports a cfscript version cfqueryparam something like: WHERE is_deleted = #QueryParam(myvar, 'cf_sql_bit')# which is much nicer than: WHERE is_deleted = <cfqueryparam value="1" cfsqltype="cf_sql_bit" />... read more »

• Hal Helms On Object Oriented Programming - Day One

  Posted on Oct 21, 2008 at 8:55 AM

  Thanks for giving us a summary of your day. Interesting reading. Totally agree with your last para "how bad it is to program before you understand the use cases." It can be a fatal mistake, we're all code junkies and just want to code, but it really is worth taking some time out first :)... read more »
