getDescriptorForType()

getField(Descriptors.FieldDescriptor field)
public Object getField(Descriptors.FieldDescriptor field)
getFieldBuilder(Descriptors.FieldDescriptor field)
public Message.Builder getFieldBuilder(Descriptors.FieldDescriptor field)
Get a nested builder instance for the given field.
Normally, we hold a reference to the immutable message object for the message type field.
Some implementations(the generated message builders), however, can also hold a reference to
the builder object (a nested builder) for the field.
If the field is already backed up by a nested builder, the nested builder will be
returned. Otherwise, a new field builder will be created and returned. The original message
field (if exist) will be merged into the field builder, which will then be nested into its
parent builder.
NOTE: implementations that do not support nested builders will throw
UnsupportedOperationException.
getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)
TODO(jieluo): Clear it when all subclasses have implemented this method.
getRepeatedField(Descriptors.FieldDescriptor field, int index)
public Object getRepeatedField(Descriptors.FieldDescriptor field, int index)
getRepeatedFieldBuilder(Descriptors.FieldDescriptor field, int index)
public Message.Builder getRepeatedFieldBuilder(Descriptors.FieldDescriptor field, int index)
Get a nested builder instance for the given repeated field instance.
Normally, we hold a reference to the immutable message object for the message type field.
Some implementations(the generated message builders), however, can also hold a reference to
the builder object (a nested builder) for the field.
If the field is already backed up by a nested builder, the nested builder will be
returned. Otherwise, a new field builder will be created and returned. The original message
field (if exist) will be merged into the field builder, which will then be nested into its
parent builder.

mergeFrom(Message other)
public DynamicMessage.Builder mergeFrom(Message other)
Merge other into the message being built. other must have the exact same type
as this (i.e. getDescriptorForType() == other.getDescriptorForType()).
Merging occurs as follows. For each field:
- For singular primitive fields, if the field is set in
other, then other's
value overwrites the value in this message.
- For singular message fields, if the field is set in
other, it is merged into the
corresponding sub-message of this message using the same merging rules.
- For repeated fields, the elements in
other are concatenated with the elements in
this message.
For oneof groups, if the other message has one of the fields set, the group of this message
is cleared and replaced by the field of the other message, so that the oneof constraint is
preserved.
This is equivalent to the Message::MergeFrom method in C++.
