expand
public PCollection<Row> expand(PCollection<T> input)
Description copied from class:PTransform
Override this method to specify how thisPTransform
should be expanded on the givenInputT
.NOTE: This method should not be called directly. Instead apply the
PTransform
should be applied to theInputT
using theapply
method.Composite transforms, which are defined in terms of other transforms, should return the output of one of the composed transforms. Non-composite transforms, which do not apply any transforms internally, should return a new unbound output and register evaluators (via backend-specific registration methods).
