All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`PAssert.SingletonAssert<T>`	`inEarlyPane(BoundedWindow window)` Creates a new `PAssert.SingletonAssert` like this one, but with the assertion restricted to only run on the provided window, running the checker only on early panes for each key.
`PAssert.SingletonAssert<T>`	`inFinalPane(BoundedWindow window)` Creates a new `PAssert.SingletonAssert` like this one, but with the assertion restricted to only run on the provided window, running the checker only on the final pane for each key.
`PAssert.SingletonAssert<T>`	`inLatePane(BoundedWindow window)` Creates a new `PAssert.SingletonAssert` with the assertion restricted to only run on the provided window, running the checker only on late panes for each key.
`PAssert.SingletonAssert<T>`	`inOnlyPane(BoundedWindow window)` Creates a new `PAssert.SingletonAssert` like this one, but with the assertion restricted to only run on the provided window.
`PAssert.SingletonAssert<T>`	`inOnTimePane(BoundedWindow window)` Creates a new `PAssert.SingletonAssert` like this one, but with the assertion restricted to only run on the provided window, running the checker only on the on-time pane for each key.
`PAssert.SingletonAssert<T>`	`isEqualTo(T expected)` Asserts that the value in question is equal to the provided value, according to `Object.equals(java.lang.Object)`.
`PAssert.SingletonAssert<T>`	`notEqualTo(T notExpected)` Asserts that the value in question is not equal to the provided value, according to `Object.equals(java.lang.Object)`.
`PAssert.SingletonAssert<T>`	`satisfies(SerializableFunction<T,java.lang.Void> checkerFn)` Applies the provided checking function (presumably containing assertions) to the value in question.

- Method Detail
  - inOnlyPane
```
PAssert.SingletonAssert<T> inOnlyPane(BoundedWindow window)
```
    Creates a new PAssert.SingletonAssert like this one, but with the assertion restricted to only run on the provided window.
    The assertion will expect outputs to be produced to the provided window exactly once. If the upstream Trigger may produce output multiple times, consider instead using inFinalPane(BoundedWindow) or inOnTimePane(BoundedWindow).
    
    Returns:
    
    a new PAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inFinalPane
```
PAssert.SingletonAssert<T> inFinalPane(BoundedWindow window)
```
    Creates a new PAssert.SingletonAssert like this one, but with the assertion restricted to only run on the provided window, running the checker only on the final pane for each key.
    If the input WindowingStrategy does not always produce final panes, the assertion may be executed over an empty input even if the trigger has fired previously. To ensure that a final pane is always produced, set the Window.ClosingBehavior of the windowing strategy (via Window.withAllowedLateness(Duration, ClosingBehavior) setting Window.ClosingBehavior to Window.ClosingBehavior.FIRE_ALWAYS).
    
    Returns:
    
    a new PAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inOnTimePane
```
PAssert.SingletonAssert<T> inOnTimePane(BoundedWindow window)
```
    Creates a new PAssert.SingletonAssert like this one, but with the assertion restricted to only run on the provided window, running the checker only on the on-time pane for each key.
    
    Returns:
    
    a new PAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inEarlyPane
```
PAssert.SingletonAssert<T> inEarlyPane(BoundedWindow window)
```
    Creates a new PAssert.SingletonAssert like this one, but with the assertion restricted to only run on the provided window, running the checker only on early panes for each key.
    
    Returns:
    
    a new PAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inLatePane
```
PAssert.SingletonAssert<T> inLatePane(BoundedWindow window)
```
    Creates a new PAssert.SingletonAssert with the assertion restricted to only run on the provided window, running the checker only on late panes for each key.
    
    Returns:
    
    a new PAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - isEqualTo
```
PAssert.SingletonAssert<T> isEqualTo(T expected)
```
    Asserts that the value in question is equal to the provided value, according to Object.equals(java.lang.Object).
    
    Returns:
    
    the same PAssert.SingletonAssert builder for further assertions
  - notEqualTo
```
PAssert.SingletonAssert<T> notEqualTo(T notExpected)
```
    Asserts that the value in question is not equal to the provided value, according to Object.equals(java.lang.Object).
    
    Returns:
    
    the same PAssert.SingletonAssert builder for further assertions
  - satisfies
```
PAssert.SingletonAssert<T> satisfies(SerializableFunction<T,java.lang.Void> checkerFn)
```
    Applies the provided checking function (presumably containing assertions) to the value in question.
    
    Returns:
    
    the same PAssert.SingletonAssert builder for further assertions
