server.base_skill.BaseSkill

class documentation

class BaseSkill(_BaseSkill):

Constructor: BaseSkill(name, suspendable, minimum_access_level, parent, ...)

Abstract base skill without state machine logic.

For skills with logic in Python, there is FiniteSkillLogicMixin and ContinuousSkillLogicMixin.

Derived classes must implement at least the reset(), start() and halt() methods for a non-suspendable skill. The _condition_skill_ready() method can be overridden in order to add skill specific conditions before the start() method is allowed to be executed by the state machine.

Method	`__init__`	Cooperative Constructor. Create a new skill instance.
Async Method	`add_feasibility_check`	Add a feasibility check for this skill.
Async Method	`add_precondition_check`	Add a precondition check for this skill.
Async Method	`_init_check`	Undocumented
Instance Variable	`_feasibility_check`	Undocumented
Instance Variable	`_precondition_check`	Undocumented

Inherited from _BaseSkill:

Async Method	`call_other_continuous_skill`	Call another continuous skill from this skill.
Async Method	`call_other_finite_skill`	Call another finite skill from this skill.
Async Method	`wait_for_state`	Undocumented
Property	`current_state`	Return the current state of the skill.
Property	`ua_state_machine`	Undocumented
Async Method	`_condition_is_suspendable`	Undocumented

Async Method	`_write_current_state`	Undocumented
Instance Variable	`_called_skills`	Undocumented
Instance Variable	`_condition`	Undocumented
Instance Variable	`_current_state`	Undocumented
Instance Variable	`_suspendable`	Undocumented
Instance Variable	`_ua_current_state`	OPC UA node if the state variable of the state machine.
Instance Variable	`_ua_state_machine`	OPC UA base node of state machine.
