public final class Context extends 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.

Overrides
getDefaultInstanceForType()
public Context getDefaultInstanceForType()
getLifespanCount()
public int getLifespanCount()
Optional. The number of conversational query requests after which the
context expires. The default is 0. If set to 0, the context expires
immediately. Contexts expire automatically after 20 minutes if there
are no matching queries.
int32 lifespan_count = 2;
| Returns |
|---|
| Type | Description |
int | The lifespanCount.

getName()
Required. The unique identifier of the context. Supported formats:
projects/<Project ID>/agent/sessions/<Session ID>/contexts/<Context
ID>,projects/<Project ID>/locations/<Location ID>/agent/sessions/<Session
ID>/contexts/<Context ID>,projects/<Project ID>/agent/environments/<Environment ID>/users/<User
ID>/sessions/<Session ID>/contexts/<Context ID>,projects/<Project ID>/locations/<Location
ID>/agent/environments/<Environment ID>/users/<User ID>/sessions/<Session
ID>/contexts/<Context ID>,
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:
system_counters
*_id_dialog_context*_dialog_params_size
string name = 1;
| Returns |
|---|
| Type | Description |
String | The name.
|
getNameBytes()
public ByteString getNameBytes()
Required. The unique identifier of the context. Supported formats:
projects/<Project ID>/agent/sessions/<Session ID>/contexts/<Context

getParameters()
public Struct getParameters()
Optional. The collection of parameters associated with this context.
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 then use
map, otherwise, depending on the parameter value type, it could be one of
string, number, boolean, null, list or map.
- MapValue value: If parameter's entity type is a composite entity then use
map from composite entity property names to property values, otherwise,
use parameter value.
.google.protobuf.Struct parameters = 3;
| Returns |
|---|
| Type | Description |
Struct | The parameters.

getParametersOrBuilder()
public StructOrBuilder getParametersOrBuilder()
Optional. The collection of parameters associated with this context.
