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