-
hasContext
public final boolean hasContext()For responses, this returns true if the service returned a value for the Context 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. -
context
The contextual metadata to use when getting recommendations. Contextual metadata includes any interaction information that might be relevant when getting a user's recommendations, such as the user's current location or device type.
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
hasContext()
method.- Returns:
- The contextual metadata to use when getting recommendations. Contextual metadata includes any interaction information that might be relevant when getting a user's recommendations, such as the user's current location or device type.
-
filterArn
The ARN of the filter to apply to the returned recommendations. For more information, see Filtering Recommendations.
When using this parameter, be sure the filter resource is
ACTIVE
.- Returns:
- The ARN of the filter to apply to the returned recommendations. For more information, see Filtering Recommendations.
When using this parameter, be sure the filter resource is
ACTIVE
.
-
hasFilterValues
public final boolean hasFilterValues()For responses, this returns true if the service returned a value for the FilterValues 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. -
filterValues
The values to use when filtering recommendations. For each placeholder parameter in your filter expression, provide the parameter name (in matching case) as a key and the filter value(s) as the corresponding value. Separate multiple values for one parameter with a comma.
For filter expressions that use an
INCLUDE
element to include items, you must provide values for all parameters that are defined in the expression. For filters with expressions that use anEXCLUDE
element to exclude items, you can omit thefilter-values
.In this case, Amazon Personalize doesn't use that portion of the expression to filter recommendations.For more information, see Filtering recommendations and user segments.
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
hasFilterValues()
method.- Returns:
- The values to use when filtering recommendations. For each placeholder parameter in your filter
expression, provide the parameter name (in matching case) as a key and the filter value(s) as the
corresponding value. Separate multiple values for one parameter with a comma.

-
recommenderArn
The Amazon Resource Name (ARN) of the recommender to use to get recommendations. Provide a recommender ARN if you created a Domain dataset group with a recommender for a domain use case.
- Returns:
- The Amazon Resource Name (ARN) of the recommender to use to get recommendations. Provide a recommender ARN if you created a Domain dataset group with a recommender for a domain use case.
-
hasPromotions
public final boolean hasPromotions()For responses, this returns true if the service returned a value for the Promotions 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. -
promotions
The promotions to apply to the recommendation request. A promotion defines additional business rules that apply to a configurable subset of recommended items.
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
hasPromotions()
method.- Returns:
- The promotions to apply to the recommendation request. A promotion defines additional business rules that apply to a configurable subset of recommended items.
-
hasMetadataColumns
public final boolean hasMetadataColumns()For responses, this returns true if the service returned a value for the MetadataColumns 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. -
metadataColumns
If you enabled metadata in recommendations when you created or updated the campaign or recommender, specify the metadata columns from your Items dataset to include in item recommendations. The map key is
ITEMS
and the value is a list of column names from your Items dataset. The maximum number of columns you can provide is 10.For information about enabling metadata for a campaign, see Enabling metadata in recommendations for a campaign. For information about enabling metadata for a recommender, see Enabling metadata in recommendations for a recommender.
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
hasMetadataColumns()
method.- Returns:
- If you enabled metadata in recommendations when you created or updated the campaign or recommender,
specify the metadata columns from your Items dataset to include in item recommendations. The map key is
ITEMS
and the value is a list of column names from your Items dataset. The maximum number of columns you can provide is 10.For information about enabling metadata for a campaign, see Enabling metadata in recommendations for a campaign.

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. -
getValueForField
Description copied from class:SdkRequest
Used to retrieve the value of a field from any class that extendsSdkRequest
. The field name specified should match the member name from the corresponding service-2.json model specified in the codegen-resources folder for a given service. The class specifies what class to cast the returned value to. If the returned value is also a modeled class, theSdkRequest.getValueForField(String, Class)
method will again be available.- Overrides:
getValueForField
in classSdkRequest
- Parameters:
fieldName
- The name of the member to be retrieved.clazz
- The class to cast the returned object to.- Returns:
- Optional containing the casted return value
