updateExecutionInput

public void updateExecutionInput(ExecutionInput executionInput)

engineRun

public CompletableFuture<ExecutionResult> engineRun(Supplier<CompletableFuture<ExecutionResult>> engineRun)

Only used once outside of this class: when the execution starts

throwIfCancelled

public void throwIfCancelled()
                      throws AbortExecutionException

This will abort the execution via throwing AbortExecutionException if the ExecutionInput has been cancelled

Throws:

AbortExecutionException

possibleCancellation

public @Nullable Throwable possibleCancellation(@Nullable Throwable currentThrowable)

if the passed in Throwableis non-null then it is returned as id and if there is no exception then the cancellation state is checked in ExecutionInput.isCancelled() and a AbortExecutionException is made as the returned Throwable

Parameters:

currentThrowable - the current exception state

Returns:

a current throwable or a cancellation exception or null if none are in error

ifCancelledMakeException

public @Nullable AbortExecutionException ifCancelledMakeException()

Returns:

a AbortExecutionException if the current operation has been cancelled via ExecutionInput.cancel()
