public sealed class EventInput : IMessage<EventInput>, IEquatable<EventInput>, IDeepCloneable<EventInput>, IBufferMessage, IMessage
Events allow for matching intents by event name instead of the natural
language input. For instance, input {event: { name: "welcome_event",
parameters: { name: "Sam" } }> can trigger a personalized welcome response.
The parameter name may be used by the agent in the response:
"Hello #welcome_event.name! What can I do for you today?".
Required. The language of this query. See Language
Support
for a list of the currently supported language codes. Note that queries in
the same session do not necessarily need to specify the same language.
The collection of parameters associated with the event.
Depending on your protocol or client library language, this is a
map, associative array, symbol table, dictionary, or JSON object
composed of a collection of (MapKey, MapValue) pairs:
MapKey type: string
MapKey value: parameter name
MapValue type:
If parameter's entity type is a composite entity: map
Else: depending on parameter value type, could be one of string,
number, boolean, null, list or map
MapValue value:
If parameter's entity type is a composite entity:
map from composite entity property names to property values
