Method Details
-
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 specifyexternalId:
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 specifyexternalId:
followed by the external ID. For more information, see Using external IDs in the IoT SiteWise User Guide.
-
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.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.

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 theisEmpty()
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
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
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:

in interfaceToCopyableBuilder<VariableValue.Builder,

- a builder for type T

equalsBySdkFields
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 anSdkPojo
class, and is generated based on a service model.If an
SdkPojo
class does not have any inherited fields,equalsBySdkFields
andequals
are essentially the same.- Specified by:
equalsBySdkFields
in interfaceSdkPojo
- Parameters:
obj
- the object to be compared with- Returns:
- true if the other object equals to this object by sdk fields, false otherwise.
-
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. -
