Action Block Structure

Field	Type	Required	Description
blockOptions	JsonObject	+	Action block options
blockOptions.method	JsonObject	+	Action description
blockOptions.method.args	JsonObject	+	Action description arguments that should be read from field attribute
blockOptions.method.name	string	+	Name of action
fields	JsonArray	+	Array of fields that must be extracted by the blockOptions.method.args names
fields[].name	string	+	Name of the field block corresponding of the declaration in blockOptions.method.args
fields[].type	string	–	Represents the Item Value Type
fields[].value	string	+	Value should be corresponded to the fields[].type
delay	JsonObject	–	Delay to action after event arises. If this field is absent or is empty then delay is absent.
blockMeta	JsonObject	–	Block metadata information. Intended to save data needed for user interfaces.
delay.seconds	int	–	Seconds number of delay
delay.minutes	int	–	Minutes number of delay
delay.hours	int	–	Hours number of delay
delay.days	int	–	Days number of delay
control	JsonObject	–	Control flow of execution of this action
control.exception	JsonObject	–	Exceptions for execution of the action
exec_policy	string	–	It is execution policy of block. The block policy have higher priority then policy of scene ( see description of hub.scenes.create ). If block policy is absent then block inherits policy of scene. The block policy can have next states: check_result – result of execution each block should checked and scene should be failed in case if block is failed; ignore_result – result of execution each block should be ignored and checked only in the end of scene execution. If any action was failed than partially_finished status. If all blocks have this status and all of them are failed than failed status.

Execution policies

Available policies:

check_result – the result of execution of each block is checked and the scene marked failed in case if any block has failed.
ignore_result – the result of execution of each block is ignored and checked only at the end of scene execution.
wait_result – is a mix of ignore_result and check_result. Scenes with the exec_policy wait_result should execute their actions one by one, i.e. start the next action after the previous one has finished. Execution continues even if the previous action fails.

For scenes with ignore_result and wait_result policies: if any action has failed, then the scene will have partially_finished status; if all actions have failed – failed.
