class Empty[T <: AnyRef] extends NullSafeValidator[T]

type HasEmpty = AnyRef { def isEmpty: Boolean }

A structural type representing any object that can be empty.
class NotEmpty[T <: AnyRef] extends NullSafeValidator[T]

A validator that operates on objects that can be empty, and succeeds only if the provided instance is not empty.

An implicit conversion to enable any collection-like object (e.g. strings, options) to be handled by the com.wix.accord.combinators.CollectionCombinators.Empty and com.wix.accord.combinators.CollectionCombinators.NotEmpty combinators.
java.lang.String does not directly implement isEmpty (in practice it is implemented in scala.collection.IndexedSeqOptimized, via an implicit conversion and an inheritance stack), and this is a case where the Scala compiler does not always infer structural types correctly. By requiring a view bound from T to scala.collection.GenTraversableOnce we can force any collection-like structure to conform to the structural type com.wix.accord.combinators.HasEmpty, and by requiring a view bound from T to com.wix.accord.combinators.HasEmpty at the call site (e.g. com.wix.accord.dsl.empty) we additionally support any class that directly conforms to the structural type as well.
T
The type that conforms, directly or implicitly, to com.wix.accord.combinators.HasEmpty.
gto
An object that is, or is implicitly convertible to, scala.collection.GenTraversableOnce.
returns
The specified object, strictly-typed as com.wix.accord.combinators.HasEmpty.
