Method Details
-
hasNonKeyAttributes
public final boolean hasNonKeyAttributes()For responses, this returns true if the service returned a value for the NonKeyAttributes 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. -
nonKeyAttributes
The nonkey attributes that are projected into the index. For each attribute, provide the attribute name.
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
hasNonKeyAttributes()
method.- Returns:
- The nonkey attributes that are projected into the index. For each attribute, provide the attribute name.
-
projectionType
The types of attributes that are projected into the index. Valid values are as follows:
-
ALL
-
INCLUDE
-
KEYS_ONLY

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.
