getDefaultInstanceForType()

public DynamicMessage getDefaultInstanceForType()

Returns
Type	Description
DynamicMessage

getDescriptorForType()

public Descriptors.Descriptor getDescriptorForType()

Returns
Type	Description
Descriptors.Descriptor

getField(Descriptors.FieldDescriptor field)

public Object getField(Descriptors.FieldDescriptor field)

Parameter
Name	Description
field	Descriptors.FieldDescriptor

Returns
Type	Description
Object

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.

Parameter
Name	Description
field	Descriptors.FieldDescriptor

Returns
Type	Description
Message.Builder

Overrides

AbstractMessage.Builder<BuilderType>.getFieldBuilder(Descriptors.FieldDescriptor field)

getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

Returns
Type	Description
Descriptors.FieldDescriptor

Overrides

AbstractMessage.Builder<BuilderType>.getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

getRepeatedField(Descriptors.FieldDescriptor field, int index)

public Object getRepeatedField(Descriptors.FieldDescriptor field, int index)

Parameters
Name	Description
field	Descriptors.FieldDescriptor
index	int

Returns
Type	Description
Object

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.

NOTE: implementations that do not support nested builders will throw UnsupportedOperationException.

isInitialized()

public boolean isInitialized()

Returns
Type	Description

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++.

Parameter
Name	Description
other	Message

Type	Description
DynamicMessage.Builder

Overrides

AbstractMessage.Builder<BuilderType>.mergeFrom(Message other)
