public static interface MessageLite.Builder extends MessageLiteOrBuilder, Cloneable
Modifier and Type | Method and Description |
---|---|
MessageLite |
build()
Constructs the message based on the state of the Builder.
|
MessageLite |
buildPartial()

build() , but does not throw an exception if the message
is missing required fields. |
MessageLite.Builder |
clear()
Resets all fields to their default values.
|
MessageLite.Builder |
clone()
Clones the Builder.
|
boolean |
mergeDelimitedFrom(InputStream input)
Like
mergeFrom(InputStream) , but does not read until EOF. |
boolean |
mergeDelimitedFrom(InputStream input,
ExtensionRegistryLite extensionRegistry)
Like
mergeDelimitedFrom(InputStream) but supporting extensions. |
MessageLite.Builder |
mergeFrom(byte[] data)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(byte[] data,
ExtensionRegistryLite extensionRegistry)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(byte[] data,
int off,
int len)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(byte[] data,
int off,
int len,
ExtensionRegistryLite extensionRegistry)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(ByteString data)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(ByteString data,
ExtensionRegistryLite extensionRegistry)
Parse
data as a message of this type and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(CodedInputStream input)
Parses a message of this type from the input and merges it with this
message.
|
MessageLite.Builder |
mergeFrom(CodedInputStream input,
ExtensionRegistryLite extensionRegistry)
Like
mergeFrom(CodedInputStream) , but also
parses extensions. |
MessageLite.Builder |
mergeFrom(InputStream input)
Parse a message of this type from
input and merge it with the
message being built. |
MessageLite.Builder |
mergeFrom(InputStream input,
ExtensionRegistryLite extensionRegistry)
Parse a message of this type from
input and merge it with the
message being built. |

MessageLite.Builder clear()
MessageLite build()
UninitializedMessageException
- The message is missing one or more
required fields (i.e. MessageLiteOrBuilder.isInitialized()
returns false).
Use buildPartial()
to bypass this check.MessageLite buildPartial()
build()
, but does not throw an exception if the message
is missing required fields. Instead, a partial message is returned.
Subsequent changes to the Builder will not affect the returned message.MessageLite.Builder clone()
Object.clone()
MessageLite.Builder mergeFrom(CodedInputStream input) throws IOException
Warning: This does not verify that all required fields are present in
the input message. If you call build()
without setting all
required fields, it will throw an UninitializedMessageException
,
which is a RuntimeException
and thus might not be caught. There
are a few good ways to deal with this:
MessageLiteOrBuilder.isInitialized()
to verify that all required fields
are set before building.
buildPartial()
to build, which ignores missing
required fields.
Note: The caller should call
CodedInputStream.checkLastTagWas(int)
after calling this to
verify that the last tag seen was the appropriate end-group tag,
or zero for EOF.
IOException
MessageLite.Builder mergeFrom(CodedInputStream input, ExtensionRegistryLite extensionRegistry) throws IOException

, but also
parses extensions. The extensions that you want to be able to parse
must be registered in extensionRegistry
. Extensions not in
the registry will be treated as unknown fields.IOException

input
and merge it with the
message being built. This is just a small wrapper around
mergeFrom(CodedInputStream)
. Note that this method always
reads the entire input (unless it throws an exception). If you
want it to stop earlier, you will need to wrap your input in some
wrapper stream that limits reading. Or, use
MessageLite.writeDelimitedTo(OutputStream)
to write your message
and mergeDelimitedFrom(InputStream)
to read it.
Despite usually reading the entire input, this does not close the stream.

Instead, the size of the message (encoded as a varint) is read first,
then the message data. Use

this format.IOException
