  • Show how quick and easy it is to build and deploy – had to stretch out the content because it is so quick to build and dev.
  • After explaining, download source http://code.google.com/p/apex-lang/and include source into eclipse.
  • ===================================Null-safety===================================Save following class:public class Foo{ public void doSomethingWithAString(String str){ System.debug(str.trim().length()); }}Run anonymously:new Foo().doSomethingWithAString('test123');Run with null and of course, null pointerModify to use StringUtilspublic class Foo{ public void doSomethingWithAString(String str){ System.debug(al.StringUtils.length(al.StringUtils.trim(str))); }}===================================isEmpty/isBlank======================================================================isEmpty/isBlank===================================
  • After explaining the changes, switch to running example
  • Further explain the interaction via this diagram.Next, show more complex example with nested paginators
  • Switch to eclipse run following example anonymouslySystem.debug('\\n\\n#################################\\n' + new SoqlBuilder().selectx('ID').selectx('Name').fromx('Account').toSoql() + '\\n#################################\\n\\n');========================selecting fields========================.selectx(new Set<Object>{'ID','Name'}).fromx('Account').selectx(new List<Object>{'ID','Name'}).fromx('Account')========================relationship queries========================.selectx('id').selectx(new SoqlBuilder().selectx('id').fromx('OpportunityLineItems')).fromx('Opportunity')========================conditions - multiple ways========================.fromx('account').wherex(new FieldCondition().field('name').equals('acme'))//.fromx('account').wherex(new FieldCondition('name').equals('acme'))//.fromx('account').wherex(new FieldCondition('name',Operator.EQUALS,'acme'))//.fromx('account').wherex(new FieldCondition('name','acme')) ========================Primitives to String literals========================.fromx('account').wherex(new FieldCondition('x').equals('acme')).fromx('account').wherex(new FieldCondition('x').equals('ac\\'me')).fromx('account').wherex(new FieldCondition('x').equals(Datetime.newinstance(2010,1,1,1,1,1)))========================Conditions========================//simple NOT condition.fromx('account').wherex( new NotCondition(new AndCondition() .add(new FieldCondition('name','acme')) .add(new FieldCondition('ispartner',true))) )//nested ANDs and ORs.fromx('account').wherex( new NotCondition( new AndCondition() .add( new OrCondition() .add(new FieldCondition('name','acme')) .add( new AndCondition() .add(new FieldCondition('ispartner',true)) .add(new FieldCondition('NumberOfEmployees').lessThan(10)) ) ) .add( new OrCondition() .add(new FieldCondition('createddate').lessThan(new DateFormula().yesterdayx())) .add(new FieldCondition('Rating','Hot')) ) ))========================Wildcarding========================.fromx('account').wherex( new OrCondition() .add(new FieldCondition('name').likex('acme')) .add(new FieldCondition('name').likex('test'))).toSoql(new SoqlOptions().wildcardStringsInLikeOperators())

    3. 3. What is Code Share?<br />http://developer.force.com/codeshare<br />Directory of Open Source Projects for Force.com<br />Commit. Share. Rate. Comment.<br />
    4. 4. Using Code Share Projects<br />Search for Projects<br />Top Rated<br />Latest Added<br />All Projects<br />Stay Up to Date<br />RSS of Latest Projects<br />Rate & Comment<br />Reviews help everyone!<br />
    5. 5. Installing Code Share Projects<br />As A Package<br />Via Code Repository<br />Eclipse plugins available (subclipse, egit etc.)<br />
    6. 6.

    7. 7. Enough Talk….Let’s see a Project in Action!<br />
    8. 8. apex-lang Overview<br />A collection of just over 100 apex classes aimed at making core Apex/VF programming easier<br />Consists of only code - no objects, pages, etc<br />Has 100% code coverage<br />Project Website: <br />http://code.google.com/p/apex-lang/<br />Documented via my blog richardvanhook.com <br />Contributions are certainly welcome! Contact me at richard.vanhook@edlconsulting.com or post suggestion on my blog.<br />
    9. 9. Install Options<br />From http://code.google.com/p/apex-lang/<br />Install the Managed Package<br />Easiest install option but of course, the code is hidden<br />All classes must prefixed with al; example: al.StringUtils<br />Directly add source code<br />Download source zip file and expand into eclipse src/classes <br />Just copy & paste what you need!<br />Use apex-lang as reference<br />
    10. 10. String Manipulation<br />Use StringUtils<br />Ported directly from Apache Commons Lang therefore Javadoc for StringUtils.java very much applies. (see http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/StringUtils.html)<br />Examples:<br />All methods follow “null safe” pattern<br />Empty/Blank checks: <br />isEmpty(), isBlank(), isNotEmpty(), isNotBlank()<br />Joining Strings: <br />new List<String>{'a','b','c'} to 'a:b:c’<br />Filtering characters<br />
    11. 11. Pagination<br />Modified to utilize apex-lang pagination<br />Controller:<br />global class MyController implements SObjectPaginatorListener { <br /> global List<Account> records {get;private set;}<br /> global SObjectPaginatorpaginator {get;private set;}<br /> global MyController(){<br />paginator = new SObjectPaginator(5,this);<br />paginator.setRecords([select name from Account limit 100]); <br /> } <br /> global void handlePageChange(List<SObject> newPage){<br /> if(records == null){records = new List<Account>();}<br />records.clear();<br /> if(newPage != null && newPage.size() > 0){<br /> for(SObject record : newPage){ <br />records.add((Account)record);<br /> }<br /> }<br /> }<br />}<br />VF Page:<br /><apex:page controller="MyController"> <br /> <apex:repeat value="{!records}" var="record"> <br /> <apex:outputText value="{!record.name}"/><br/> <br /> </apex:repeat> <br /> <apex:form ><br /> <apex:commandLink value="Previous" action="{!paginator.previous}"/> <br /> &nbsp;&nbsp;|&nbsp;&nbsp;<br /> <apex:commandLink value="Next" action="{!paginator.next}"/><br /> </apex:form> <br /></apex:page><br />
    12. 12. Pagination<br />
    13. 13. SOQL Builder<br />Use SoqlBuilder.cls and supporting classes<br />Useful for dynamically creating SOQL query strings<br />Think: <br />String soql = new SoqlBuilder().fromx('Account').toSoql()<br />List<Account> a = Database.query(soql);<br />Instead of: <br />String soql = 'select id from Account';<br />List<Account> a = Database.query(soql);<br />Above example is intentionally simplified – real world use cases for SoqlBuilder more complex<br />Not intended as replacement for static query strings:<br />List<Account> a = [select id from Account];<br />
    14. 14. Recap & Summary<br />Before coding, search CodeShare!<br />Take time to rate, commit, and commit!<br />Apex-lang rocks man<br />Share the love!<br />
