Method Detail

validate

ValidationResult validate(T transition,
                          TransitionIndex<N,M,T> transitionIndex,
                          TransitionValidator.Operation operation)

Checks the transition parameter correctness with respect to current transitions on the given index.

Parameters:

transition - the transition to check

transitionIndex - the transition index

operation - the operation to accomplish

Returns:

the validation result

getFailurePolicy

default TransitionValidator.FailurePolicy getFailurePolicy()
