    Class WorldState

    WorldState contains information about the physical environment around a given robot. All of the fields within this message are optional, they can include information about the physical dimensions of an obstacle, the freespace of a robot, and any desired transforms between a given reference frame and a new target reference frame.

    Properties

    a list of obstacles expressed as a geometry and the reference frame in which it was observed; this field is optional

    from field: repeated viam.common.v1.GeometriesInFrame obstacles = 1;

    transforms: commonApi.Transform[]

    a list of Transforms, optionally with geometries. Used as supplemental transforms to transform a pose from one reference frame to another, or to attach moving geometries to the frame system. This field is optional

    from field: repeated viam.common.v1.Transform transforms = 3;

    runtime: ProtoRuntime
    typeName: "viam.common.v1.WorldState"

    Methods

    • Parse from binary data, merging fields.

      Repeated fields are appended. Map entries are added, overwriting existing keys.

      If a message field is already present, it will be merged with the new data.

      Parameters

      • bytes: Uint8Array
      • Optionaloptions: Partial<BinaryReadOptions>

      Returns this

    • Parse a message from a JSON value.

      Parameters

      • jsonValue: JsonValue
      • Optionaloptions: Partial<JsonReadOptions>

      Returns this

    • Parse a message from a JSON string.

      Parameters

      • jsonString: string
      • Optionaloptions: Partial<JsonReadOptions>

      Returns this

    • Retrieve the MessageType of this message - a singleton that represents the protobuf message declaration and provides metadata for reflection- based operations.

      Returns MessageType<commonApi.WorldState>

    • Serialize the message to binary data.

      Parameters

      • Optionaloptions: Partial<BinaryWriteOptions>

      Returns Uint8Array

    • Serialize the message to a JSON value, a JavaScript value that can be passed to JSON.stringify().

      Parameters

      • Optionaloptions: Partial<JsonWriteOptions>

      Returns JsonValue

    • Override for serialization behavior. This will be invoked when calling JSON.stringify on this message (i.e. JSON.stringify(msg)).

      Note that this will not serialize google.protobuf.Any with a packed message because the protobuf JSON format specifies that it needs to be unpacked, and this is only possible with a type registry to look up the message type. As a result, attempting to serialize a message with this type will throw an Error.

      This method is protected because you should not need to invoke it directly -- instead use JSON.stringify or toJsonString for stringified JSON. Alternatively, if actual JSON is desired, you should use toJson.

      Returns JsonValue

    • Serialize the message to a JSON string.

      Parameters

      • Optionaloptions: Partial<JsonWriteStringOptions>

      Returns string

    • Parameters

      • bytes: Uint8Array
      • Optionaloptions: Partial<BinaryReadOptions>

      Returns commonApi.WorldState

    • Parameters

      • jsonString: string
      • Optionaloptions: Partial<JsonReadOptions>

      Returns commonApi.WorldState
