    public final class Context
extends com.google.protobuf.GeneratedMessageV3
implements ContextOrBuilder
     Dialogflow contexts are similar to natural language context. If a person says
 to you "they are orange", you need context in order to understand what "they"
 is referring to. Similarly, for Dialogflow to handle an end-user expression
 like that, it needs to be provided with context in order to correctly match
 an intent.

 Using contexts, you can control the flow of a conversation. You can configure
 contexts for an intent by setting input and output contexts, which are
 identified by string names. When an intent is matched, any configured output
 contexts for that intent become active. While any contexts are active,
 Dialogflow is more likely to match intents that are configured with input
 contexts that correspond to the currently active contexts.

 For more information about context, see the
 [Contexts guide](https://cloud.google.com/dialogflow/docs/contexts-overview).

      • getName

        public String getName()
         Required. The unique identifier of the context. Format:
 `projects/<Project ID>/agent/sessions/<Session ID>/contexts/<Context ID>`,
 or `projects/<Project ID>/agent/environments/<Environment ID>/users/<User

 The `Context ID` is always converted to lowercase, may only contain
 characters in `a-zA-Z0-9_-%` and may be at most 250 bytes long.

 If `Environment ID` is not specified, we assume default 'draft'
 environment. If `User ID` is not specified, we assume default '-' user.

 The following context names are reserved for internal use by Dialogflow.
 You should not use these contexts or create contexts with these names:

 map from composite entity property names to property values, otherwise,
 use parameter value.
