Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`default void`	`shutdown()`	Shutdown hook called by the `AbstractBindingHarness`.
`default void`	`startup()`	Startup hook called by the `AbstractBindingHarness`.
`java.util.concurrent.CompletableFuture<QualifiedValue>`	`transform(QualifiedValue value)`	When the binding or previous transform emits a value, it will be given to this method.

- Method Detail
  - startup
```
default void startup()
```
    Startup hook called by the AbstractBindingHarness. This method will run on the SessionContext's ExecutionQueue thread. The default implementation is a no-op.
  - shutdown
```
default void shutdown()
```
    Shutdown hook called by the AbstractBindingHarness. This method will run on the SessionContext's ExecutionQueue thread. The default implementation is a no-op.
  - transform
```
java.util.concurrent.CompletableFuture<QualifiedValue> transform(@Nonnull
                                                                 QualifiedValue value)
                                                          throws java.lang.Throwable
```
    When the binding or previous transform emits a value, it will be given to this method. The expectation is that the transform will then push the transformed value onto the callback given to it in the factory
    
    Parameters:
    
    value - The input value to the Transform. It could be the output value of the binding itself if the transform is first in the chain, or it could be a transformed value if it is after the first in the chain. The input QualifiedValue can never be null (though the value it wraps can be null)
    
    Throws:
    
    java.lang.Throwable - If there is a problem with the transformation
