Method Detail

matches

boolean matches(AppliedPTransform<?,?,?> application)

matchesDuringValidation

default boolean matchesDuringValidation(AppliedPTransform<?,?,?> application)

An AppliedPTransform matched by a PTransformMatcher will be replaced during pipeline surgery, and is often expected to be gone in the new pipeline. For the AppliedPTransform that is expected to remain in the pipeline after surgery, the corresponding PTransformMatcher should override this method, such that it will not be matched during the validation.
