getRestrictPredicate

@Nullable
public @Nullable BiPredicate<Relation,Entity> getRestrictPredicate()

Instead of always restricting the removal of relation X if relation Y is set, this method allows to provide an additional condition that needs to evaluate to true to deny the removal. This predicate is applied to each set blocking relation to determine whether the removal should be restricted.

Returns:

a BiPredicate that receives the set blocking relation that is currently being tested as first argument and the entity to be removed as second argument

setRestrictPredicate

public void setRestrictPredicate(BiPredicate<Relation,Entity> restrictPredicate)

getErrorMessageFormatter

@Nullable
public @Nullable BiFunction<Entity,Set<String>,TextMessage> getErrorMessageFormatter()

Returns:

a function to create a text message. This function receives the entity that couldn't be deleted and a set with all text resources for the relations that caused the removal to fail.

setErrorMessageFormatter

public void setErrorMessageFormatter(BiFunction<Entity,Set<String>,TextMessage> errorMessageFormatter)
