public static final class StandardTags.CallTag
extends Tag

Marks program locations that represent a call to other guest language functions, methods or closures.

Use case descriptions:

• Debugger: Marks program locations where returning or stepping out from a method/procedure/closure call should halt. The debugger will halt at the code location that has just executed the call that returned.

The CallTag uses the identifier "CALL". A node tagged with StandardTags.RootTag must provide a source section, if its root node provides a source section.

If the a node tagged with call returns a non null value then it must be an interop value. There are assertions in place verifying this when Java assertions are enabled (-ea).
