What are default methods for batch apex?
The different method of Batch Apex Class are:
- start method: It is used to collect the variables, records or objects to be passed to the method execute.
- execute method: It performs the processing for each batch of data passed to the method.
- finish method: It is used to execute post-processing operations.
What is the return type of start method in batch apex?
To collect the records or objects to pass to the interface method execute , call the start method at the beginning of a batch Apex job. This method returns either a Database. QueryLocator object or an iterable that contains the records or objects passed to the job.
Which is an example of using batch apex?
Using Batch Apex, you can process records asynchronously in batches (hence the name, “Batch Apex”) to stay within platform limits. If you have a lot of records to process, for example, data cleansing or archiving, Batch Apex is probably your best solution.
Do you need a token to use apex?
From the Forms menu one entry could open a Form, another one an APEX page. But this is just one example, basically the idea is to auto-logon a user to an APEX app just by providing a one-time token. To be able to do that, we need a token table at first.
Which is the second possible solution for token based authentication?
The second possible solution for token based authentication is by using the Invalid Session Function. It looks very similar to our first approach, the big difference is that his procedure will be invoked by APEX only if there is no or an invalid session and that it will create a new session with every call.
Which is the best way to authenticate apex?
Starting with APEX 5.1.4 it is possible to use :APP_AJAX_X01 instead of manually parsing the query string in the Invalid Session Function. Using X01 (or any other Xxx Parameter) has a big advantage over using a Page or Application Item: it doesn’t conflict with any kind of Session State Protection.
