Trigger class

Any condition on a device (DeviceDescriptor) which starts or stops TaskDescriptors at certain points in time when the condition applies. The condition can either be time-bound, based on data streams, initiated by a user of the platform, or a combination of these.

Properties

$type ↔ String?

The runtime class name (type) of this object. Used for deserialization from JSON objects.

getter/setter pair, inherited

fromJsonFunction → Function

The function which can convert a JSON string to an object of this type.

no setter, override

hashCode → int

The hash code for this object.

no setter, inherited

jsonType → String

Return the __type to be used for JSON serialization of this class. Default is runtimeType. Only specify this if you need another type.

no setter, override

requiresMasterDevice ↔ bool?

Determines whether the trigger needs to be evaluated on a master device (MasterDeviceDescriptor). For example, this is the case when the trigger is time bound and needs to be evaluated by a task scheduler running on a master device.

getter/setter pair

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

sourceDeviceRoleName ↔ String?

The device role name from which the trigger originates.

getter/setter pair

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

Return a JSON encoding of this object.

override

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
