CTS_add_rule: Add Rule to Element

Description

Takes the ui elements in the state and element and attempts to add a rule.

Usage

CTS_add_rule(state, element)

Value

Element with the results of adding the rule. The rares list element can be used to determine the exit status of the function.

• RULE_IS_GOOD If true it indicates that the pieces of the rule from the UI check out.

• RULE_UPDATED If RULE_IS_GOOD and RULE_UPDATED is true then a previous rule definition was overwritten. If RULE_IS_GOOD is TRUE and RULE_UPDATED is FALSE then a new rule was added.

• notify_text Text for notify message

• notify_id Notification ID

• notify_type Notification type

• msgs Vector of messages.

Arguments

state

CTS state from CTS_fetch_state()

element

Element list from CTS_fetch_current_element()

Details

This depends on the following UI values in the state and element

• state[["CTS"]][["ui"]][["rule_name"]]

• state[["CTS"]][["ui"]][["rule_condition"]]

• state[["CTS"]][["ui"]][["rule_type"]]

  • For rule type "dose"

    • state[["CTS"]][["ui"]][["action_dosing_state"]]

    • state[["CTS"]][["ui"]][["action_dosing_values"]]

    • state[["CTS"]][["ui"]][["action_dosing_times"]]

    • state[["CTS"]][["ui"]][["action_dosing_durations"]]

  • For rule type "set state"

    • state[["CTS"]][["ui"]][["action_set_state_state"]]

    • state[["CTS"]][["ui"]][["action_set_state_values"]]

  • For rule type "manual code"

    • state[["CTS"]][["ui"]][["action_manual_code"]]
