clone

public abstract BuilderType clone()

Description copied from interface: MessageLite.Builder

Clones the Builder.

Specified by:

clone in interface MessageLite.Builder

Overrides:

clone in class java.lang.Object

Object.clone()

mergeFrom

public BuilderType mergeFrom(CodedInputStream input)
                      throws java.io.IOException

Description copied from interface: MessageLite.Builder

Parses a message of this type from the input and merges it with this message.

Warning: This does not verify that all required fields are present in the input message. If you call MessageLite.Builder.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:

• Call MessageLiteOrBuilder.isInitialized() to verify that all required fields are set before building.
• Use 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.

Throws:

java.io.IOException

mergeFrom

public abstract BuilderType mergeFrom(CodedInputStream input,
                                      ExtensionRegistryLite extensionRegistry)
                               throws java.io.IOException

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.mergeFrom(CodedInputStream), 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.

Specified by:

mergeFrom in interface MessageLite.Builder

Throws:

java.io.IOException

mergeFrom

public BuilderType mergeFrom(ByteString data)
                      throws InvalidProtocolBufferException

Description copied from interface: MessageLite.Builder

Parse data as a message of this type and merge it with the message being built. This is just a small wrapper around MessageLite.Builder.mergeFrom(CodedInputStream).

Specified by:

mergeFrom in interface MessageLite.Builder

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

public BuilderType mergeFrom(ByteString data,

Description copied from interface: MessageLite.Builder

Parse data as a message of this type and merge it with the message being built. This is just a small wrapper around MessageLite.Builder.mergeFrom(CodedInputStream,ExtensionRegistryLite).

Returns:

this

Throws:

mergeFrom

public BuilderType mergeFrom(java.io.InputStream input)
                      throws java.io.IOException

Description copied from interface: MessageLite.Builder

Parse a message of this type from input and merge it with the message being built. This is just a small wrapper around MessageLite.Builder.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 MessageLite.Builder.mergeDelimitedFrom(InputStream) to read it.

Despite usually reading the entire input, this does not close the stream.

Specified by:

mergeFrom in interface MessageLite.Builder

Returns:

this

Throws:

java.io.IOException

mergeFrom

public BuilderType mergeFrom(java.io.InputStream input,
                             ExtensionRegistryLite extensionRegistry)
                      throws java.io.IOException

Description copied from interface: MessageLite.Builder

Parse a message of this type from input and merge it with the message being built. This is just a small wrapper around MessageLite.Builder.mergeFrom(CodedInputStream,ExtensionRegistryLite).

Throws:

mergeDelimitedFrom

public boolean mergeDelimitedFrom(java.io.InputStream input,
                                  ExtensionRegistryLite extensionRegistry)
                           throws java.io.IOException

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.mergeDelimitedFrom(InputStream) but supporting extensions.

Specified by:

mergeDelimitedFrom in interface MessageLite.Builder

Throws:

java.io.IOException

mergeDelimitedFrom

public boolean mergeDelimitedFrom(java.io.InputStream input)
                           throws java.io.IOException

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.mergeFrom(InputStream), but does not read until EOF. Instead, the size of the message (encoded as a varint) is read first, then the message data. Use MessageLite.writeDelimitedTo(OutputStream) to write messages in this format.

Specified by:

mergeDelimitedFrom in interface MessageLite.Builder

Returns:

True if successful, or false if the stream is at EOF when the method starts. Any other error (including reaching EOF during parsing) will cause an exception to be thrown.

Throws:

java.io.IOException
