Hello All.
What would be the best way to implement this, I mean, the server where Im
deploying right now its a G5, with 3 GB Ram, and I need the fuzzy matches to
be as fast as possible,
So I was thininking to surround the textefield where the user can type with
a WOForm, and place inside a AjaxObserveField, which makes me have some
questions:
I have the follwoing in the html
<wo:form multipleSubmit = "$true">
<wo:AjaxUpdateContainer id="transTextContainer">
<div id ="newTextArea">
<wo:text value = "$newTranslationValue"
class = "descrTA" id="newTA"/>
</div>
</wo:AjaxUpdateContainer>
<div class = "button_holder" id
="modificationButtons">
<div id="addTrans">
<table>
<tr>
<td class ="butCell"
><wo:AjaxSubmitButton effect="highlight" id ="addT" class ="moreButton"
value ="Add" updateContainerID ="WGInfomation" action ="$addUnits"
onClickBefore = "verifyData()" onComplete="clearData"/></td>
<td class ="butCell"
><wo:AjaxSubmitButton effect="highlight" id ="updT" class ="moreButton"
value ="Update" updateContainerID ="WGInfomation" action ="$updateUnit"
onClickBefore = "verifyData()" onComplete="clearData"/></td>
</tr>
</table>
</div>
<div id="saveTrans">
<div id="close"><wo:AjaxSubmitButton
class="moreButton" value="Delete Selected" action="$deleteLastWord"
updateContainerID ="WGInfomation" onComplete="clearData"/></div>
</div><!-- /Button_holder -->
<wo:AjaxSubmitButton id ="commit" class =
"moreButton" value= "Commit Translation Set" action =
"$commitTranslatinoSet" updateContainerID ="WGInfomation" onClick =
"Element.show('busy2')" onComplete = "function(x){Element.hide('busy2')}"/>
</div><!-- /modifyButton -->
</wo:form >
as you can see the textfield its alreay surrownded by a WOForm, what happens
if I surrowunded again?. with a <WOForm action = "$fuzzyMatchesSearch">
will the AajxObjeserField trigger that method?
Second, in the fuzzyMatchesSearch method I will call the implementation the
Levenshtein Algorithm, so given an Array of stirngs I will check each one
and select jsut the ones that retturns a value of no more than 2, (if I
understood good the algorithm).
Im new to the threading thing, so, should I create a class that implement
Runnable, and in the run() method run the Levensthein Algorithm, and from
within the fuzzyMatchesSearch methohd run create the instance of my Runnable
Class and run the thread?.. or..... Im really divagating here, you guys know
much better than me so Im asking an advice please.
Thanks tons
