Each of the surround descriptors defines a possible type of code fragment that can be surrounded - for example, one surround descriptor can handle surrounding expressions, and another can handle statements.
Each surround descriptor, in turn, contains an array of [`Surrounder`](upsource:///platform/lang-api/src/com/intellij/lang/surroundWith/Surrounder.java) objects, defining specific templates which can be used for surrounding the selected code fragment (for example, _Surround With if_, _Surround With for_, and so on).
When the _Surround With_ action is invoked, the IDE queries all surround descriptors for the language until it finds one that returns a non-empty array from its `getElementsToSurround()` method.
When the <menupath>Code | Surround With...</menupath> action is invoked, the IDE queries all surround descriptors for the language until it finds one that returns a non-empty array from its `getElementsToSurround()` method.
Then it calls the [`Surrounder.isApplicable()`](upsource:///platform/lang-api/src/com/intellij/lang/surroundWith/Surrounder.java) method for each surrounder in that descriptor to check if the specific template is applicable in the current context.
Once the user selects a specific surrounder from the popup menu, the [`Surrounder.surroundElements()`](upsource:///platform/lang-api/src/com/intellij/lang/surroundWith/Surrounder.java) method is used to execute the surround action.
