Class Transform
- All Implemented Interfaces:
Serializable
,SdkPojo
,ToCopyableBuilder<Transform.Builder,
Transform>
Contains an asset transform property. A transform is a one-to-one mapping of a property's data points from one form
to another. For example, you can use a transform to convert a Celsius data stream to Fahrenheit by applying the
transformation expression to each data point of the Celsius stream. A transform can only have a data type of
DOUBLE
and consume properties with data types of INTEGER
or DOUBLE
.

Method Details
-
expression
The mathematical expression that defines the transformation function. You can specify up to 10 variables per expression. You can specify up to 10 functions per expression.
For more information, see Quotas in the IoT SiteWise User Guide.
- Returns:
- The mathematical expression that defines the transformation function. You can specify up to 10 variables
per expression. You can specify up to 10 functions per expression.

hasVariables
public final boolean hasVariables()For responses, this returns true if the service returned a value for the Variables 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. -
variables
The list of variables used in the expression.
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
hasVariables()
method.- Returns:
- The list of variables used in the expression.
-
processingConfig
The processing configuration for the given transform property. You can configure transforms to be kept at the edge or forwarded to the Amazon Web Services Cloud. You can also configure transforms to be computed at the edge or in the cloud.
- Returns:
- The processing configuration for the given transform property. You can configure transforms to be kept at the edge or forwarded to the Amazon Web Services Cloud. You can also configure transforms to be computed at the edge or in the cloud.

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. -
