  • Method Details

    • propertyId

      public final String propertyId()

      The ID of the property to use as the variable. You can use the property name if it's from the same asset model. If the property has an external ID, you can specify externalId: followed by the external ID. For more information, see Using external IDs in the IoT SiteWise User Guide.

      Returns:
      The ID of the property to use as the variable. You can use the property name if it's from the same asset model. If the property has an external ID, you can specify externalId: followed by the external ID. For more information, see Using external IDs in the IoT SiteWise User Guide.

    • hierarchyId

      public final String hierarchyId()

      The ID of the hierarchy to query for the property ID. You can use the hierarchy's name instead of the hierarchy's ID. If the hierarchy has an external ID, you can specify externalId: followed by the external ID. For more information, see Using external IDs in the IoT SiteWise User Guide.

      You use a hierarchy ID instead of a model ID because you can have several hierarchies using the same model and therefore the same propertyId. For example, you might have separately grouped assets that come from the same asset model. For more information, see Asset hierarchies in the IoT SiteWise User Guide.

      Returns:
      The ID of the hierarchy to query for the property ID. You can use the hierarchy's name instead of the hierarchy's ID. If the hierarchy has an external ID, you can specify externalId: followed by the external ID. For more information, see Using external IDs in the IoT SiteWise User Guide.

    • hasPropertyPath

      public final boolean hasPropertyPath()
      For responses, this returns true if the service returned a value for the PropertyPath 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.

    • propertyPath

      public final List<AssetModelPropertyPathSegment> propertyPath()

      The path of the property.

      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 hasPropertyPath() method.

      Returns:
      The path of the property.

    • toBuilder

      public VariableValue.Builder toBuilder()
      Description copied from interface: ToCopyableBuilder
      Take this object and create a builder that contains all of the current property values of this object.
      Specified by:
      toBuilder in interface ToCopyableBuilder<VariableValue.Builder,VariableValue>
      Returns:
      a builder for type T

    • builder

      public static VariableValue.Builder builder()

    • serializableBuilderClass

      public static Class<? extends VariableValue.Builder> serializableBuilderClass()

    • hashCode

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

    • equals

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

    • equalsBySdkFields

      public final boolean equalsBySdkFields(Object obj)
      Description copied from interface: SdkPojo
      Indicates whether some other object is "equal to" this one by SDK fields. An SDK field is a modeled, non-inherited field in an SdkPojo class, and is generated based on a service model.

      If an SdkPojo class does not have any inherited fields, equalsBySdkFields and equals are essentially the same.

      Specified by:
      equalsBySdkFields in interface SdkPojo
      Parameters:
      obj - the object to be compared with
      Returns:
      true if the other object equals to this object by sdk fields, false otherwise.

    • 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)

    • sdkFields

      public final List<SdkField<?>> sdkFields()
      Specified by:
      sdkFields in interface SdkPojo
      Returns:
      List of SdkField in this POJO. May be empty list but should never be null.
