Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`java.util.List<DoFnSignature.Parameter>`	`extraParameters()`	Types of optional parameters of the annotated method, in the order they appear.
`default boolean`	`observesWindow()`	Whether this method observes - directly or indirectly - the window that an element resides in.
`@Nullable TypeDescriptor<? extends BoundedWindow>`	`windowT()`	The type of window expected by this method, if any.

- Method Detail
  - extraParameters
```
java.util.List<DoFnSignature.Parameter> extraParameters()
```
    Types of optional parameters of the annotated method, in the order they appear.
    Validation that these are allowed is external to this class.
  - observesWindow
```
default boolean observesWindow()
```
    Whether this method observes - directly or indirectly - the window that an element resides in.
    State, Timer, DoFn.SideInput parameters indirectly observe the window, because they are each scoped to a single window.
  - windowT
```
@Nullable TypeDescriptor<? extends BoundedWindow> windowT()
```
    The type of window expected by this method, if any.
