abstract class GroupClauseVerifier<S : ContractState, T : Any> : SingleClause


Constructors

<init> GroupClauseVerifier()

Properties

clauses abstract val clauses: List<GroupClause<S, T>>
requiredCommands open val requiredCommands: Set<Class<out CommandData>>

Classes for commands which must ALL be present in transaction for this clause to be triggered

Functions

verify open fun verify(tx: TransactionForContract, commands: Collection<AuthenticatedObject<CommandData>>): Set<CommandData>

Verify the transaction matches the conditions from this clause. For example, a "no zero amount output" clause would check each of the output states that it applies to, looking for a zero amount, and throw IllegalStateException if any matched.
