SennMagic

Updates incoming in 3.6

2011-05-09T11:18:00.000+02:00

Hi all,

version 3.6 of SennMagic is currently in the making and there's some nice new stuff in there!

AutowiredHttpServlet: an HttpServlet that allows your Spring beans to be automatically injected if you annotate them with the Spring @Autowired annotation.

The Directory class has been retrofitted to extend java.io.File. Some methods have been removed to avoid duplicate methods with java.io.File.

The Chainable Collections API has some new stuff aswell!

First of all, the implementations have been changed so they return their own implementation instead of the interface. This way specific implementation methods can be added to the end of the chain if needed.
For example in ChainableHashMap:

public ChainableMap<K, V> add(K key, V value) {...}

has been changed to:

public ChainableHashMap<K, V> add(K key, V value) {...}

Second, I've added ChainableVector and ChainableHashtable to the CCA.

And as always methods have been added to various existing classes.

Stay tuned!

Bart

Not dead but very much alive!

2011-01-23T20:50:00.000+01:00

It's been a while since I updated anything on the SennMagic project, but here it is!

Version 3.5 has some minor changes and additions in existing classes (DFCUtils, GeneralUtils) but most importantly:
The 'chainable' collections api!

Don't you just hate it when you are instantiating objects and you have to pass a Collection instance and you can't do it in one line because the collection needs one or more items in it, like this:

car.setPassengers(new ArrayList<Passenger>()); // you can only add an empty list
//so you have to do:
List<Passenger> passengers = new ArrayList<Passenger>();
passengers.add(new Passenger("Bart"));
car.setPassengers(passengers);

That's all in the past with the chainable collections api!

The chainable collections api has extra methods (with very recognizable, straightforward names) to add/remove/replace items in the collections, but instead of the normal return value, it returns the collection itself. This enables you to 'chain' actions like this:

//same as previous example:
car.setPassengers(new ChainableArrayList<Passenger>().put(new Passenger("Bart")));

I have created implementations for the most commonly used collections (+maps):

ChainableList extends List

ChainableArrayList extends ArrayList implements ChainableList
ChainableLinkedList extends LinkedList implements ChainableList

ChainableMap extends Map

ChainableHashMap extends HashMap implements ChainableMap
ChainableLinkedHashMap extends LinkedHashMap implements ChainableMap
ChainableTreeMap extends TreeMap implements ChainableMap

ChainableQueue extends Queue

ChainablePriorityQueue extends PriorityQueue implements ChainableQueue

ChainableSet extends Set

ChainableHashSet extends HashSet implements ChainableSet
ChainableLinkedHashSet extends LinkedHashSet implements ChainableSet
ChainableTreeSet extends TreeSet implements ChainableSet

It's already proven to be quite handy, especially when creating unit tests, in multiple projects, by multiple developers.

Get it while it's still hot!

New version! Focus on Java Reflection

2010-05-06T20:32:00.002+02:00

Hello young ,and less young, padawans

I was gathering stuff to put in my next release, but it was nothing mind-boggling.
Until a couple of days ago...

I was trying to create a method that would be able to call an SBO (Documentum Service-Based Business Object) without having to import the SBO-interface and having to add the jar to my classpath.

I know this can easily be done using Java Reflection, but the problem was: I wanted to create one method to call any SBO.

Something like this:

public Object callSBO(String sboName, String methodName, Object... args){...}

Now, that isn't such a hard thing to do.

Get the SBO-service
use Reflection to get the method and invoke it

That is, when all your arguments are Objects!

I came across the problem of calling an SBO that takes an int value + some Objects.
The problem is that Java reflection wraps an int-value into an Integer to be able to put it in a Object-array.
Since we don't want to pass both an Object[] array and the corresponding Class[] array, we have to create the Class-array on the fly.
So we start with 2 ints, and unwillingly end up with 2 Integers.

Now I don't know if you have ever tried calling a function that takes int-values with Integer values through reflection, but I can assure you, it results in nice NoSuchMethodExceptions.

As a possible solution I tried to replace all primitive-wrappers-classes in the Class-array with primitive-classes, but what if you ever come across a method like this:

public void foo(int i, String s, Double d){...}

Ye, I know, functions that mix primitives with wrappers are rare, but exist nonetheless! So ignoring that possibility would be a bad choice.
That left me with 2 options:

Also pass an array with the corresponding classes to the method (no way!)
Work some MAGIC

I obviously decided to choose the latter, and I'll present it soon!

It's easy to use, just pass a Class/Object, methodName and an array of Objects to the method (as varArgs), and let SennMagic decide which values should be primitive and which should be wrappers.

I created the method to able to use in any case, and I also added a specific method callService(...) to DFCUtils.

Now you can call any SBO without having to add the jar to the classpath of the (web)application.

Till soon...

Cheers,

Bart

DFC with multiple dfc.properties files

2010-04-13T10:37:00.005+02:00

UPDATED: I have called quits on this little sideproject. It was working ok-ish, but it was not performant enough and I just couldn't bring myself to make this work.
Source code can be handed out if you'd like to give it a try.

For now I'll just focus (lol) on the SennMagic library

I developed a small Java package that allows you to code a DFC based application that uses multiple dfc.properties files.

I'm still in the testing phase, but if you want to try it out (and help me test it) you can contact me and ask for the package.

It has to be tested in
- various OS's
- different Documentum setups (Oracle, SQL Server)
- single- & multithreaded DFC apps (this might show us a few bugs)
- webapps

You can contact me through
- replying here
- mail
- twitter
- EMC Community Forums

Use "SennMagic DFC" as subject.

Bart

EDIT: to avoid confusion: this jar cannot be found on our SourceForge page yet!

Bugfix

2010-03-31T14:59:00.000+02:00

I fixed the bug in CountryUtils!

You can find the updated version of SennMagic at SourceFourge!

Cheers!

Bug in CountryUtils

2010-03-25T14:20:00.002+01:00

Hello all,

I discovered that a there's a bug in CountryUtils.
It can't find the country_codes.xml file.

I'll fix this asap!

For the time being, if you want to use CountryUtils, place the resources-folder (found in senn-magic-3.2-src.zip/com/senn/magic/util/resources) in the root of your application.

My apologies!

Bart

SM 3.2 released! And how!!!

2010-03-03T20:47:00.001+01:00

Hi everybody,

it's been a while since the last version, but here it is!

SENNMAGIC 3.2!

A whole lot has been added since 3.1!

com.senn.magic.util.WebUtils
com.senn.magic.util.CountryUtils
com.senn.magic.util.DSUtils
com.senn.magic.io.Directory

And ofcourse, many methods added to the existing classes!

Check out the javadoc and release notes for more info!

As always you can find it @ our sourceforge page

Cheers,
Bart

Next version of SennMagic in the making!

2010-02-12T09:57:00.000+01:00

Hi everybody!

I'm glad to announce that if I've got alot of new stuff for the new version of SennMagic!
Some new Util-classes, some methods updated or improved and even a special dedicated POJO class for working with Filesystem directories (as opposed to using java.io.File which is not very straightforward for directories).

So how's that for a sneakpeak!

I don't know yet when I'll release it, but it won't be long!

Stay tuned!

Bart

SennMagic 3.1 = 3.0 fixed + extras!

2010-01-27T09:39:00.001+01:00

I fixed the compile-issue with SennMagic 3.0 and as an apology, I added some new methods that I was saving for a future release.

GeneralUtils.canBeBoolean(String):boolean
GeneralUtils.canBeByte(String):boolean
GeneralUtils.canBeDouble(String):boolean
GeneralUtils.canBeFloat(String):boolean
GeneralUtils.canBeInteger(String):boolean
GeneralUtils.canBeLong(String):boolean
GeneralUtils.canBeShort(String):boolean

These methods check if a String vaue can be converted to the respective type.
It saves you the trouble of having to catch NumberFormatException everytime you want to convert a String to something.

I also added

StringUtils.isValid(String):boolean

Which is a pretty simple and straightforward check. I use it all the time to check my string values.
It checks if a String value is not null and the length is > 0.

So, SennMagic 3.1 is available for download!

Only one place: http://sourceforge.net/projects/sennmagic

Bug in SennMagic 3.0

2010-01-25T13:25:00.001+01:00

Hi,

I just noticed that SennMagic 3.0 is compiled to 1.6.
I have no idea why my Ant build decided to build it in 6 all of a sudden...

I will fix this tonight when I get back from work, so expect a small update soon!

My apologies,

Bart

SennMagic 3.0!

2010-01-22T22:36:00.003+01:00

Hi everybody,

I know it has been a while since I last updated SennMagic, but that's because I decided to wait till I had enough new material.

So here it is, the new version, and yes it's another MAJOR release.

There's been some serious changes since 2.0 so I decided to bump it up to 3.0 instead of 2.1 or whatever.

So, what's new...

I changed the classnames to reflect their purpose better:
- LogMagic => SimpleLogger
- FileMagic => FileUtils
- TextMagic => StringUtils
- UtilMagic => GeneralUtils
I added DFCUtils, which contains some handy methods for DFC actions (more info below)
I added ignoreCase support to StringUtils.getOccurrencesCount(...)
I decided to split the jar, source and javadoc into 3 packages
1. package: senn-magic-3.0.jar
2. source: senn-magic-3.0-src.zip
3. docs: senn-magic-3.0-javadoc.zip
Last but no least, I refactored some methods and reformatted the code + javadoc

So what is DFCUtils...?

I've been busy doing alot of development on Documentum projects.
Documentum is an enterprise content management platform by EMC² (www.emc.com).

To access the Documentum content and metadata from Java, DFC is used.
DFC, or Documentum Foundation Classes, is an extensive API that allows you to do almost anything in Documentum.

DFCUtils is a helper class that contains methods to create sessions and execute DQL (Documentum Query Language).
So it saves me (and hopefully some other people too) some time.

So that's it, check out the new version at: http://sourceforge.net/projects/sennmagic

Cheers,
Bart

SennMagic 2.0!

2009-12-09T21:50:00.003+01:00

Hello all,

a new version of SennMagic has been released!

BE CAREFUL, THE PACKAGES HAVE CHANGED QUITE A BIT SO IT YOU WILL NEED TO REFACTOR WHEN USING THE NEW VERSION IN AN EXISTING PROJECT (just hit Shift+Ctrl+O in Eclipse ;) )

So what has changed:

FileMagic and TextMagic have been moved to the com.senn.magic.util package.
LogMagic has been moved to the com.senn.magic.logging package.

TextMagic.split(String, String):List has been added for completion reasons
TextMagic.split(String, char):List has been added for completion reasons

The class com.senn.magic.util.UtilMagic has been added to SennMagic.
This class will contain all useful methods that don't belong in the specific Magic-classes.

For now there only is UtilMagic.asArrayList(S[]):ArrayList< S >.

senn-magic-2.0.jar can be downloaded from http://sourceforge.net/projects/sennmagic

Cheers,
Bart
