Method Detail

eventId

public final String eventId()

An ID associated with the event. If an event ID is not provided, Amazon Personalize generates a unique ID for the event. An event ID is not used as an input to the model. Amazon Personalize uses the event ID to distinquish unique events. Any subsequent events after the first with the same event ID are not used in model training.

Returns:

An ID associated with the event. If an event ID is not provided, Amazon Personalize generates a unique ID for the event. An event ID is not used as an input to the model. Amazon Personalize uses the event ID to distinquish unique events. Any subsequent events after the first with the same event ID are not used in model training.

eventType

public final String eventType()

The type of event, such as click or download. This property corresponds to the EVENT_TYPE field of your Interactions schema and depends on the types of events you are tracking.

Returns:

The type of event, such as click or download. This property corresponds to the EVENT_TYPE field of your Interactions schema and depends on the types of events you are tracking.

eventValue

public final Float eventValue()

The event value that corresponds to the EVENT_VALUE field of the Interactions schema.

Returns:

The event value that corresponds to the EVENT_VALUE field of the Interactions schema.

itemId

public final String itemId()

The item ID key that corresponds to the ITEM_ID field of the Interactions schema.

Returns:

The item ID key that corresponds to the ITEM_ID field of the Interactions schema.

properties

public final String properties()

A string map of event-specific data that you might choose to record. For example, if a user rates a movie on your site, other than movie ID (itemId) and rating (eventValue) , you might also send the number of movie ratings made by the user.

Each item in the map consists of a key-value pair. For example,

{"numberOfRatings": "12"}

The keys use camel case names that match the fields in the Interactions schema. In the above example, the numberOfRatings would match the 'NUMBER_OF_RATINGS' field defined in the Interactions schema.

Returns:

A string map of event-specific data that you might choose to record. For example, if a user rates a movie on your site, other than movie ID (itemId) and rating (eventValue) , you might also send the number of movie ratings made by the user.

Each item in the map consists of a key-value pair. For example,

{"numberOfRatings": "12"}

The keys use camel case names that match the fields in the Interactions schema. In the above example, the numberOfRatings would match the 'NUMBER_OF_RATINGS' field defined in the Interactions schema.

sentAt

public final Instant sentAt()

The timestamp (in Unix time) on the client side when the event occurred.

Returns:

The timestamp (in Unix time) on the client side when the event occurred.

recommendationId

public final String recommendationId()

The ID of the recommendation.

Returns:

The ID of the recommendation.

hasImpression

public final boolean hasImpression()

For responses, this returns true if the service returned a value for the Impression 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.

impression

public final List<String> impression()

A list of item IDs that represents the sequence of items you have shown the user. For example, ["itemId1", "itemId2", "itemId3"].

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 hasImpression() method.

Returns:

A list of item IDs that represents the sequence of items you have shown the user. For example, ["itemId1", "itemId2", "itemId3"].
