Abstract Value Members

  3. abstract def init(view: BaseAccountStateView, consensusEpochNumber: Int): Unit
  4. abstract def process(invocation: Invocation, view: BaseAccountStateView, context: ExecutionContext): Array[Byte]

    Apply invocation to the given view.

    Apply invocation to the given view. Possible results:

    • applied as expected: return byte[]
    • invocation valid and (partially) executed, but operation "failed": throw ExecutionFailedException
    • invocation invalid and must not exist in a block: throw any other Exception
    invocation

    invocation to execute

    view

    state view

    context

    contextual information accessible during execution. It contains also the consensus epoch number

    returns

    return data on successful execution

    Exceptions thrown

    ExecutionFailedException revert-and-consume-all-gas, also mark the message as "failed"

    ExecutionRevertedException revert-and-keep-gas-left, also mark the message as "failed"

    RuntimeException any other exceptions are considered as "invalid message"
