findMissingFields

static java.util.List<java.lang.String> findMissingFields(MessageOrBuilder message)

Populates this.missingFields with the full "path" of each missing required field in the given message.

mergeFieldFrom

static boolean mergeFieldFrom(CodedInputStream input,
                              UnknownFieldSet.Builder unknownFields,
                              ExtensionRegistryLite extensionRegistry,

                       throws java.io.IOException

Parses a single field into MergeTarget. The target can be Message.Builder, FieldSet or MutableMessage.

Package-private because it is used by GeneratedMessage.ExtendableMessage.

Parameters:

tag - The tag, which should have already been read.

unknownFields - If not null, unknown fields will be merged to this UnknownFieldSet, otherwise unknown fields will be discarded.

Returns:

true unless the tag is an end-group tag.

Throws:

java.io.IOException
