Interface ResolverCreateHooks.PreWriteCheck

All Superinterfaces:

BiFunction<FDBRecordContext,LocatableResolver,CompletableFuture<Boolean>>

Enclosing class:

ResolverCreateHooks

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface ResolverCreateHooks.PreWriteCheck
extends BiFunction<FDBRecordContext,LocatableResolver,CompletableFuture<Boolean>>

Functional interface for the safety check that will be run before writing a mapping in the LocatableResolver. The passed LocatableResolver will be the resolver we are attempting to write to. Implementations can then use the transaction provided to check whether that resolver is the correct one. If not, implementations must throw an exception.
