Abstract Value Members

abstract def apply(a: A, state: S): ((MissingAndErroneousFeatureInfo, Option[B]), S)

Given an a and some state, produce output, including a new state.
Given an a and some state, produce output, including a new state.
When using this function, the user is responsible for keeping track of, and providing the state.
The implementation of this function should be referentially transparent.
a
input
state
the state
returns
a tuple where the first element is a Tuple2 whose first element is missing and error information and second element is an optional result. The second element of the outer Tuple2 is the new state.
abstract val initialState: S

Some initial state that can be used on the very first call to apply(A, S).
Some initial state that can be used on the very first call to apply(A, S).
returns
some state.

def statefulMap[In <: Seq[A], Out](as: SeqLike[A, In], state: S)(implicit cbf: CanBuildFrom[In, ((MissingAndErroneousFeatureInfo, Option[B]), S), Out]): Out

Apply the apply(A, S) method to the elements of the sequence.
Apply the apply(A, S) method to the elements of the sequence. In the first application of apply(A, S), state will be used as the state. In subsequent applications, the state will come from the state generated in the output of the previous application of apply(A, S).
NOTE: This method isn't really parallelizable via chunking. The way to parallelize this method is to provide a separate starting state for each unit of parallelism.

as
input to map.
state
the initial state to use at the start of mapping.
cbf
object responsible for building the output collection.
def statefulMap(as: Iterator[A], state: S): Iterator[((MissingAndErroneousFeatureInfo, Option[B]), S)]

Apply the apply(A, S) method to the elements of the iterator.
Apply the apply(A, S) method to the elements of the iterator. In the first application of apply(A, S), state will be used as the state. In subsequent applications, the state will come from the state generated in the output of the previous application of apply(A, S).
For more information, see com.eharmony.aloha.util.StatefulMapOps
as
Note the first element of as will be forced in this method in order to construct the output.
state
the initial state to use at the start of the iterator.
returns
an iterator containing the a mapped to a (MissingAndErroneousFeatureInfo, Option[B]) along with the resulting state that is created in the process.
