Interface ExecutableType

  • All Superinterfaces:
    AnnotatedConstruct, TypeMirror

    public interface ExecutableType
extends TypeMirror
    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.

    • Method Detail

      • getTypeVariables

        List<? extends TypeVariable> getTypeVariables​()
        Returns the type variables declared by the formal type parameters of this executable.
        Returns:
        the type variables declared by the formal type parameters, or an empty list if there are none

      • getReturnType

        TypeMirror getReturnType​()
        Returns the return type of this executable. Returns a NoType with kind VOID if this executable is not a method, or is a method that does not return a value.
        Returns:
        the return type of this executable

      • getParameterTypes

        List<? extends TypeMirror> getParameterTypes​()
        Returns the types of this executable's formal parameters.
        Returns:
        the types of this executable's formal parameters, or an empty list if there are none

      • getReceiverType

        TypeMirror getReceiverType​()
        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

      • getThrownTypes

        List<? extends TypeMirror> getThrownTypes​()
        Returns the exceptions and other throwables listed in this executable's throws clause.
        Returns:
        the exceptions and other throwables listed in this executable's throws clause, or an empty list if there are none.
