## Package org.apache.tapestry5.func

Light-weight functional programming for Flows of values

See:
Description

Interface Summary
Flow<T> | A flow is a a functional interface for working with an ordered collection of elements.
FlowOperations<T,FT> |
LazyFunction<T> | A lazy function is used to populate a `Flow` incrementally.
LazyValue<T> | A function that returns a value, allowing the computation of that value to be deferred as late as possible.
Mapper<S,T> | Interface for operation `Flow.map(Mapper)` to define how Flow elements are mapped from one type to another (or otherwise transformed).
Mapper2<A,B,C> | A generalization of `Mapper` for a two-input function.
Predicate<T> | Used when filtering a collection of objects of a given type; the predicate is passed each object in turn, and returns true to include the object in the result collection.
Reducer<A,T> | A reducer takes an accumulator value and a single value from a collection and computes a new accumulator value.
Worker<T> | An operational function used with a `Flow`.
ZippedFlow<A,B> | The result of the `Flow.zipWith(Flow)` method (or created from a Map via `F.zippedFlow(Map)`), a Flow of combined `Tuple` values (that can be deconstructed, eventually, using `ZippedFlow.unzip()`).

Class Summary
F | Functional operations on collections with generics support.
LazyContinuation<T> | The result of the evaluation of a `LazyFunction`.
LazyZipValue<A,B> |
Tuple<A,B> | A Tuple holds two values of two different types.
