## Detailed Description

class HBhvConditionSensorActive : public HBhvCondition

  The HBhvConditionSensorActive class evaluates if the given sensor is currently active.

  Public Functions

  HBhvConditionSensorActive(const char *target, const char *hevent, bool invert, HBhvSensor *sensor)

    Constructs an HBhvConditionSensorActive object.

    Parameters

      - target – The descriptor of the target sensor. You can use HBhvTargetObject::CreateTargetString() to generate this string.

      - hevent – The event type.

      - invert – Pass true to invert the condition. In other words, this condition will return true if the condition evaluates to false and false if the condition evaluates to true.

      - sensor – A pointer to the HBhvSensor object that this condition belongs to.

  virtual void Evaluate(bool &and_flag, bool &or_flag)

    Evaluates the condition.

    Parameters

      - and_flag – Returns true if the target sensor was active or false if it is inactive. Note that this flag will return the opposite values if the invert flag is set to true.

      - or_flag – Result of evaluation

  virtual void Serialize(HUtilityXMLGenerator *xmlgen)

    Writes XML data to a buffer.
