A URL/resource name that uniquely identifies the type of the serialized
protocol buffer message. This string must contain at least
one "/" character. The last segment of the URL's path must represent
the fully qualified name of the type (as in
path/google.protobuf.Duration). The name should be in a canonical form
(e.g., leading "." is not accepted).
In practice, teams usually precompile into the binary all types that they
expect it to use in the context of Any. However, for URLs which use the
https, or no scheme, one can optionally set up a type
server that maps type URLs to message definitions as follows:
Note: this functionality is not currently available in the official protobuf release, and it is not used for type URLs beginning with type.googleapis.com.
Schemes other than
https (or the empty scheme) might be
used with implementation specific semantics.
from field: string type_url = 1;
Must be a valid serialized protocol buffer of the above specified type.
from field: bytes value = 2;
Compare with a message of the same type.
Parse from binary data, merging fields.
Repeated fields are appended. Map entries are added, overwriting existing keys.
If a message field is already present, it will be merged with the new data.
Parse a message from a JSON value.
Parse a message from a JSON string.
Retrieve the MessageType of this message - a singleton that represents the protobuf message declaration and provides metadata for reflection- based operations.
Serialize the message to binary data.
Override for serialization behavior. This will be invoked when calling JSON.stringify on this message (i.e. JSON.stringify(msg)).
Note that this will not serialize google.protobuf.Any with a packed message because the protobuf JSON format specifies that it needs to be unpacked, and this is only possible with a type registry to look up the message type. As a result, attempting to serialize a message with this type will throw an Error.
This method is protected because you should not need to invoke it directly -- instead use JSON.stringify or toJsonString for stringified JSON. Alternatively, if actual JSON is desired, you should use toJson.
Serialize the message to a JSON string.
Generated using TypeDoc
Anycontains an arbitrary serialized protocol buffer message along with a URL that describes the type of the serialized message.
Protobuf library provides support to pack/unpack Any values in the form of utility functions or additional generated methods of the Any type.
Example 1: Pack and unpack a message in C++.
Example 2: Pack and unpack a message in Java.
Example 3: Pack and unpack a message in Python.
Example 4: Pack and unpack a message in Go
The pack methods provided by protobuf library will by default use 'type.googleapis.com/full.type.name' as the type URL and the unpack methods only use the fully qualified type name after the last '/' in the type URL, for example "foo.bar.com/x/y.z" will yield type name "y.z".
The JSON representation of an
Anyvalue uses the regular representation of the deserialized, embedded message, with an additional field
@typewhich contains the type URL. Example:
If the embedded message type is well-known and has a custom JSON representation, that representation will be embedded adding a field
valuewhich holds the custom JSON in addition to the
@typefield. Example (for message [google.protobuf.Duration]):
from message google.protobuf.Any
