MessageOptions

Is this message deprecated? Depending on the target platform, this can emit Deprecated annotations for the message, or it will be completely ignored; in the very least, this is a formalization for deprecating messages.

Enable the legacy handling of JSON field name conflicts. This lowercases and strips underscored from the fields before comparison in proto3 only. The new behavior takes json_name into account and applies to proto2 as well.

Returns the value of the deprecatedLegacyJsonFieldConflicts field if present, otherwise null.

Returns the value of the deprecated field if present, otherwise null.

Any features defined in the specific edition. WARNING: This field should only be used by protobuf plugins or special cases like the proto compiler. Other uses are discouraged and developers should rely on the protoreflect APIs for their client language.

Returns the value of the features field if present, otherwise null.

Whether the message is an automatically generated map entry type for the maps field.

Returns the value of the mapEntry field if present, otherwise null.

Set true to use the old proto1 MessageSet wire format for extensions. This is provided for backwards-compatibility with the MessageSet wire format. You should not use this for any other reason: It's less efficient, has fewer features, and is more complicated.

Returns the value of the messageSetWireFormat field if present, otherwise null.

Disables the generation of the standard "descriptor()" accessor, which can conflict with a field of the same name. This is meant to make migration from proto1 easier; new code should avoid fields named "descriptor".

Returns the value of the noStandardDescriptorAccessor field if present, otherwise null.

Returns the field-presence view for this MessageOptions instance.

The parser stores options it doesn't recognize here. See above.

Copies the original message, including unknown fields.
