Class Property

    • Method Detail

      • id

        public final String id()

        The ID of the asset property.

        Returns:
        The ID of the asset property.
      • name

        public final String name()

        The name of the property.

        Returns:
        The name of the property.
      • alias

        public final String alias()

        The alias that identifies the property, such as an OPC-UA server data stream path (for example, /company/windfarm/3/turbine/7/temperature). For more information, see Mapping industrial data streams to asset properties in the IoT SiteWise User Guide.

        Returns:
        The alias that identifies the property, such as an OPC-UA server data stream path (for example, /company/windfarm/3/turbine/7/temperature). For more information, see Mapping industrial data streams to asset properties in the IoT SiteWise User Guide.
      • unit

        public final String unit()

        The unit (such as Newtons or RPM) of the asset property.

        Returns:
        The unit (such as Newtons or RPM) of the asset property.
      • type

        public final PropertyType type()

        The property type (see PropertyType). A property contains one type.

        Returns:
        The property type (see PropertyType). A property contains one type.
      • hasPath

        public final boolean hasPath()
        For responses, this returns true if the service returned a value for the Path property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.
      • path

        public final List<AssetPropertyPathSegment> path()

        The structured path to the property from the root of the asset.

        Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

        This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasPath() method.

        Returns:
        The structured path to the property from the root of the asset.
      • externalId

        public final String externalId()

        The external ID of the asset property. For more information, see Using external IDs in the IoT SiteWise User Guide.

        Returns:
        The external ID of the asset property. For more information, see Using external IDs in the IoT SiteWise User Guide.
      • hashCode

        public final int hashCode()
        Overrides:
        hashCode in class Object
      • equals

        public final boolean equals​(Object obj)
        Overrides:
        equals in class Object
      • toString

        public final String toString()
        Returns a string representation of this object. This is useful for testing and debugging. Sensitive data will be redacted from this string using a placeholder value.
        Overrides:
        toString in class Object
      • getValueForField

        public final <T> Optional<T> getValueForField​(String fieldName,
                                                      Class<T> clazz)
