Is there any way to see all built in classes and interfaces as we can see in NetBeans for Java?

  • By "see" do you mean an equivalent of Javadoc?

  • As we can see built in classes on netBeans by (ctrl + clicking) on built in className in java. Means what is written in standard built in classes and in built in interfaces .... Commented Jul 11, 2015 at 10:00
  • I've modified your question to be more specific. Please re-edit if I've got it wrong.

There are several code editors for Apex typically built into an IDE and what you are looking for is a feature of those. The Apex can be parsed locally to offer code completions, but it is the Salesforce server that has a full (and up to date) model of the Apex source code, the platform provided APIs, the SObjects and other component definitions. So using a server API such as the relatively new Tooling API's "code completions" is a good way for the editor to go.

The code editor in the Developer Console supports this feature.

Of the available IDE's that support this feature, MavensMate is frequently recommended. Support for this feature is work in progress in the Force.com IDE provided by Salesforce. There are other editors/IDEs too that others may comment on.

Here is an example of the code completion available in the Developer Console:

  • Thanks for your response @Keith C, i used force.com iDE in eclipse. But in this ide where i can view schedulable interface and other things, for example when we use list<string> Lstr; Lstr.size() returns size of collection and size method is defined somewhere in library so where i can see standard built in list collection size() method. are u getting my question....

  • @AmitChaudhary The Force.com IDE is behind other editors/IDEs at the moment (and what you get depends on what version you are using). I've added a screen shot from the Developer Console that shows the list size method and the same code completion is available in MavensMate.

  • This shows size() method return type and parameter, i want to see defination of this method.. Commented Jul 11, 2015 at 12:56
  • @AmitChaudhary In Java, Eclipse code completion also links you into the Javadoc (which is nice but not critical), but there isn't a direct equivalent to Javadoc for Apex. The Apex code completion provides the signature - the method name and parameter names and types - and that most of the time gives you all the information you need - size and sort are pretty self documenting. If you need more detail you'll have to Google for it.
