### Constructors

<init> | `CompositeClause()` Abstract supertype for clauses which compose other clauses together in some logical manner.

### Properties

clauses | `abstract val clauses: List<Clause<S, C, K>>` List of clauses under this composite clause

### Inherited Properties

requiredCommands | `open val requiredCommands: Set<Class<out CommandData>>` Determine whether this clause runs or not

### Functions

getExecutionPath | `open fun getExecutionPath(commands: List<AuthenticatedObject<C>>): List<Clause<*, *, *>>` Determine the subclauses which will be verified as a result of verifying this clause.
matchedClauses | `abstract fun matchedClauses(commands: List<AuthenticatedObject<C>>): List<Clause<S, C, K>>` Determine which clauses are matched by the supplied commands

### Extension Functions

matches | `fun <C : CommandData> Clause<*, C, *>.matches(commands: List<AuthenticatedObject<C>>): Boolean` Determine if the given list of commands matches the required commands for a clause to trigger.

### Inheritors

AllComposition | `class AllComposition<S : ContractState, C : CommandData, K : Any> : CompositeClause<S, C, K>` Compose a number of clauses, such that all of the clauses must run for verification to pass.
AnyComposition | `class AnyComposition<in S : ContractState, C : CommandData, in K : Any> : CompositeClause<S, C, K>` Compose a number of clauses, such that any number of the clauses can run.
FirstComposition | `class FirstComposition<S : ContractState, C : CommandData, K : Any> : CompositeClause<S, C, K>` Compose a number of clauses, such that the first match is run, and it errors if none is run.
