Hello all, I'm calling an Apex class called AHelper from the Developer Console, that initializes. You can render any page as a PDF by adding the renderAs attribute to the apex :page> component, and specifying “pdf” as the rendering service. For example.

Apex i. About the Tutorial. Apex is a proprietary language developed by terney.info It is a strongly typed, object- oriented programming language that.

Salesforce Apex Code is the Force programming language to write custom robust business logic and is executed in the Salesforce environment. Similar to other.
Thus each time execute is run, you are allowed queries and 50, DML rows and so on. When that execute is complete, a new one is instantiated with the next group of Accounts, with a brand new set of governor limits. Finally the finish method wraps up any loose ends as necessary, like sending a status email. So your batch that runs against 10, Accounts will actually be run in 50 separate execute transactions, each of which only has to deal with Accounts.
Governor limits still apply, but only to each transaction, along with a separate set of limits for the batch as a whole. Disadvantages of batch processing : It runs asynchronously, which can make it hard to troubleshoot without some coded debugging, logging, and persistent stateful reporting.
If you need access within execute to some large part of the full dataset being iterated, this is not available.
Each execution only has access to whatever is passed to it, although you can persist class variables by implementing Database. There is still a fairly large limit on total Heap size for the entire batch run, which means that some very complex logic may run over, and need to be broken into separate batches.
I have used apexDoc for a while and we are starting to roll it out more fully for our use at my organization. In answer to your questions 1. There is an idea of the ideas exchange for it to be done but it seems to gain very little support.
Theoretically, it should be pretty easy as apex is a Java DSL.
Have you tried running Doxygen and if so what errors does it throw up? I use ApexDoc to generate some basic output and then have a little script tied in to copy across custom css and things. I believe the IDE is being open sourced at some time in which case I would imagine the antlr grammar file would become available which may help you out. Paul Workarounds for Missing Apex Time. UPDATE As tomlogic points out, the above method is not very robust — some locales may include spaces in the date or time portion of the format, and the ordering is not consistent.
This second attempt assumes that the date and time are separated by zero or more spaces, but handles spaces within the two portions, and either ordering of date and time.
Unfortunately, the standard math methods only include simpler operations i. Keep an eye on Apex tooling api, which is used in Developer console. This is supposed to be released to public access soon. The best that you can do is to dynamically create an instance of a class that implements an interface and executes one of the methods on the interface. Apex is not a general-purpose programming language but is instead a proprietary language used for specific business logic functions.
Apex requires unit testing for development into a production environment. How Validation Rules Executed? Any record that is saved in Salesforce will run through the validation rules. Explain Considerations for Static keyword in Apex?
Static allowed only in outer class. Static variables not transferred as a part of View State. Static variables and static block run in the order in which they are written in class. Static variables are static only in the scope of a request. However; database. We can achieve the database.
DMLOptions Important Difference: If we use the DML statement insert , then in bulk operation if an error occurs, the execution will stop and Apex code throws an error which can be handled in try catch block. If DML database methods Database.
Static variables are only static within the scope of the request. They are not static across the server, or across the entire organization.
Explain few considerations for Future annotation in Apex? A parameter to the future method can only be primitive or collection of primitive data type. A future method cannot call another future method.
Used to show or hide the element. Rerender: After Ajax which component should be refreshed — available on command link, command button, action support etc.
Renderas: render page as pdf, doc and excel. What is batch apex? Why do we use batch apex?
Below is an image which gives you the complete picture of Salesforce in action. The client or user either requests or provides information to the Salesforce application. This is generally done using Visualforce.
This information is then passed on to the application logic layer, written in Apex. Depending upon the information, data is either inserted or removed from the database. Salesforce also provides you with the option of using web services to directly access the application logic. A Salesforce developer can approach development either using the declarative or programmatic options. Below is an image which provides you with details on both the declarative and programmatic approaches available at each of the user interface, business logic and data model layer.
Generally, you should use programmatic approach only when you can not achieve the necessary user-interface using the declarative approach. To access the data model, you can use the declarative approach using objects, fields and relationships.
