import javax.lang.model.element.ExecutableElement;

Represents the type of an executable. An executable is a method, constructor, or initializer.

The executable is represented as when viewed as a method (or constructor or initializer) of some reference type. If that reference type is parameterized, then its actual type arguments are substituted into any types returned by the methods of this interface.

Returns the receiver type of this executable, or NoType with kind NONE if the executable has no receiver type. An executable which is an instance method, or a constructor of an inner class, has a receiver type derived from the declaring type. An executable which is a static method, or a constructor of a non-inner class, or an initializer (static or instance), has no receiver type.
Returns:the receiver type of this executable
