Interface DiscoveryIssueReporter.Condition<T>

Enclosing interface:

DiscoveryIssueReporter

public static interface DiscoveryIssueReporter.Condition<T>

A Condition is a union of Predicate and Consumer.

Instances of this type may be used as Predicates or Consumers. For example, a Condition may be passed to Stream.filter(Predicate) if it is used for filtering, or to Stream.peek(Consumer) if it is only used for reporting or other side effects.

This interface is not intended to be implemented by clients.
