    • getArgumentTypes

      public Class<?>[] getArgumentTypes()
      Returns the argument types of the execution signature. The returned types may be null to indicate that nothing is known about argument types. If the argument returns a non-null value then the length of the array will be used for the number of expected arguments. Each value of the return array specifies the expected argument type of the execution. If an argument type is null then this indicates that the argument type is unknown.
