Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method and Description
`Coder<T>`	`getCoder()` Deprecated. instead call `PCollection.getCoder()` on the actual `PCollection` directly
`DataflowAssert.SingletonAssert<T>`	`inFinalPane(BoundedWindow window)` Creates a new `DataflowAssert.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.
`DataflowAssert.SingletonAssert<T>`	`inOnlyPane(BoundedWindow window)` Creates a new `DataflowAssert.SingletonAssert` like this one, but with the assertion restricted to only run on the provided window.
`DataflowAssert.SingletonAssert<T>`	`inOnTimePane(BoundedWindow window)` Creates a new `DataflowAssert.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.
`DataflowAssert.SingletonAssert<T>`	`is(T expected)` Deprecated. instead use `isEqualTo(Object)`
`DataflowAssert.SingletonAssert<T>`	`isEqualTo(T expected)` Asserts that the value in question is equal to the provided value, according to `Object.equals(java.lang.Object)`.
`DataflowAssert.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)`.
`DataflowAssert.SingletonAssert<T>`	`satisfies(SerializableFunction<T,Void> checkerFn)` Applies the provided checking function (presumably containing assertions) to the value in question.
`DataflowAssert.SingletonAssert<T>`	`setCoder(Coder<T> coderOrNull)` Deprecated. instead call `PCollection.setCoder(Coder)` on the actual `PCollection` directly.

- Method Detail
  - setCoder
```
@Deprecated
DataflowAssert.SingletonAssert<T> setCoder(Coder<T> coderOrNull)
```
    Deprecated. instead call PCollection.setCoder(Coder) on the actual PCollection directly.
    
    Sets the coder of the actual PCollection.
    
    Returns:
    
    the same DataflowAssert.IterableAssert builder for further assertions
  - getCoder
```
@Deprecated
Coder<T> getCoder()
```
    Deprecated. instead call PCollection.getCoder() on the actual PCollection directly
    
    Returns the coder of the actual PCollection.
  - inOnlyPane
```
DataflowAssert.SingletonAssert<T> inOnlyPane(BoundedWindow window)
```
    Creates a new DataflowAssert.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 DataflowAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inFinalPane
```
DataflowAssert.SingletonAssert<T> inFinalPane(BoundedWindow window)
```
    Creates a new DataflowAssert.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 ClosingBehavior of the windowing strategy (via Window.Bound#withAllowedLateness(Duration, ClosingBehavior) setting ClosingBehavior to ClosingBehavior#FIRE_ALWAYS).
    
    Returns:
    
    a new DataflowAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - inOnTimePane
```
DataflowAssert.SingletonAssert<T> inOnTimePane(BoundedWindow window)
```
    Creates a new DataflowAssert.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 DataflowAssert.SingletonAssert like this one but with the assertion only applied to the specified window.
  - isEqualTo
```
DataflowAssert.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 DataflowAssert.SingletonAssert builder for further assertions
  - is
```
@Deprecated
DataflowAssert.SingletonAssert<T> is(T expected)
```
    Deprecated. instead use isEqualTo(Object)
    
    Asserts that the value in question is equal to the provided value, according to Object.equals(java.lang.Object).
    
    Returns:
    
    the same DataflowAssert.SingletonAssert builder for further assertions
  - notEqualTo
```
DataflowAssert.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 DataflowAssert.SingletonAssert builder for further assertions
  - satisfies
```
DataflowAssert.SingletonAssert<T> satisfies(SerializableFunction<T,Void> checkerFn)
```
    Applies the provided checking function (presumably containing assertions) to the value in question.
    
    Returns:
    
    the same DataflowAssert.SingletonAssert builder for further assertions
