Method Detail

clear

MessageLite.Builder clear()

Resets all fields to their default values.

build

MessageLite build()

Constructs the message based on the state of the Builder. Subsequent changes to the Builder will not affect the returned message.

Throws:

UninitializedMessageException - The message is missing one or more required fields (i.e. MessageLiteOrBuilder.isInitialized() returns false). Use buildPartial() to bypass this check.

buildPartial

MessageLite buildPartial()

Like 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.

clone

MessageLite.Builder clone()

Clones the Builder.

Object.clone()

mergeFrom

MessageLite.Builder mergeFrom(CodedInputStream input)
                       throws java.io.IOException

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 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

MessageLite.Builder mergeFrom(CodedInputStream input,
                              ExtensionRegistryLite extensionRegistry)
                       throws java.io.IOException

Like 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.

Throws:

java.io.IOException

mergeFrom

MessageLite.Builder mergeFrom(ByteString data)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(ByteString data,
                              ExtensionRegistryLite extensionRegistry)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(byte[] data)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(byte[] data,
                              int off,
                              int len)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(byte[] data,
                              ExtensionRegistryLite extensionRegistry)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(byte[] data,
                              int off,
                              int len,
                              ExtensionRegistryLite extensionRegistry)
                       throws InvalidProtocolBufferException

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

Returns:

this

Throws:

InvalidProtocolBufferException

mergeFrom

MessageLite.Builder mergeFrom(java.io.InputStream input)
                       throws java.io.IOException

Parse a message of this type from 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.

Returns:

this

Throws:

java.io.IOException

mergeFrom

MessageLite.Builder mergeFrom(java.io.InputStream input,
                              ExtensionRegistryLite extensionRegistry)
                       throws java.io.IOException

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

Returns:

this

Throws:

java.io.IOException

mergeDelimitedFrom

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

Like 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.

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

mergeDelimitedFrom

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

Like mergeDelimitedFrom(InputStream) but supporting extensions.

Throws:

java.io.IOException
