find
fun <T : ContractState> findReferenceInputRef(clazz: Class<T>, predicate: Predicate<T>): StateAndRef<T>
Helper to simplify finding a single reference input matching a Predicate.
Return
the single item matching the predicate.
Parameters
clazz
The class type used for filtering via an Class.isInstance check. clazz must be an extension of ContractState.
predicate
A filtering function taking a state of type T and returning true if this is the desired item. The class filtering is applied before the predicate.
Throws
if no item, or multiple items are found matching the requirements.
