Interface CollectionConditional<C extends CollectionConditional<C>>

All Superinterfaces:

Conditional<C>, Copyable<C>

All Known Implementing Classes:

DefaultCollectionConditional

public interface CollectionConditional<C extends CollectionConditional<C>>
extends Conditional<C>

An extension of Conditional that is used for matching a set of conditionals against each member of a collection field. This conditional is useful in scenarios where the states of members of a collection are relevant to gate certain functionality.

For example, a conditional that is a match when all members of a collection have a "type" of "PRODUCT, or is empty:

 Conditionals.whenCollection("choices")
         .conditional(PropertyConditional.when("type").equalTo("PRODUCT"))
         .allMatch()
         .matchIfEmpty()
