Class MetadataKey

java.lang.Object

com.google.protobuf.AbstractMessage

io.envoyproxy.envoy.type.metadata.v3.MetadataKey
All Implemented Interfaces:
com.google.protobuf.Message, com.google.protobuf.MessageLite, com.google.protobuf.MessageLiteOrBuilder, com.google.protobuf.MessageOrBuilder, MetadataKeyOrBuilder, Serializable

public final class MetadataKey extends com.google.protobuf.GeneratedMessage implements MetadataKeyOrBuilder
 MetadataKey provides a general interface using ``key`` and ``path`` to retrieve value from
 :ref:`Metadata <envoy_v3_api_msg_config.core.v3.Metadata>`.

 For example, for the following Metadata:

 .. code-block:: yaml

 filter_metadata:
 envoy.xxx:
 prop:
 foo: bar
 xyz:
 hello: envoy

 The following MetadataKey will retrieve a string value "bar" from the Metadata.

 .. code-block:: yaml

 key: envoy.xxx
 path:
 - key: prop
 - key: foo
 
Protobuf type envoy.type.metadata.v3.MetadataKey
