Modifier and Type | Method and Description |
---|---|
MessageType |
build()
Constructs the message based on the state of the Builder.
|
MessageType |
buildPartial()
Like
MessageLite.Builder.build() , but does not throw an exception if the message is missing required
fields. |
BuilderType |
clear()
Resets all fields to their default values.
|
BuilderType |
clone()
Clones the Builder.
|
protected void |
copyOnWrite()
Called before any method that would mutate the builder to ensure that it correctly copies any
state before the write happens to preserve immutability guarantees.
|
MessageType |
getDefaultInstanceForType()
Get an instance of the type with no fields set.
|
protected BuilderType |
internalMergeFrom(MessageType message) |
boolean |
isInitialized()
Returns true if all required fields in the message and all embedded messages are set, false
otherwise.
|
BuilderType |
mergeFrom(byte[] input,
int offset,
int length)
Parse
data as a message of this type and merge it with the message being built. |
BuilderType |
mergeFrom(byte[] input,
int offset,
int length,
ExtensionRegistryLite extensionRegistry)
Parse
data as a message of this type and merge it with the message being built. |
BuilderType |
mergeFrom(CodedInputStream input,
ExtensionRegistryLite extensionRegistry)
Like
MessageLite.Builder.mergeFrom(CodedInputStream) , but also parses extensions. |
BuilderType |
mergeFrom(MessageType message)
All subclasses implement this.
