mergeFrom

public BuilderType mergeFrom(CodedInputStream input)
                                                                                   throws 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.

mergeFrom

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

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.

Returns:

this

Throws:

IOException

mergeDelimitedFrom

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

Description copied from interface: MessageLite.Builder

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

Specified by:

mergeDelimitedFrom in interface MessageLite.Builder

Throws:

IOException

mergeDelimitedFrom

public boolean mergeDelimitedFrom(InputStream input)
                           throws 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:

IOException

mergeFrom

public BuilderType mergeFrom(MessageLite other)

Description copied from interface: MessageLite.Builder

Merge other into the message being built. other must have the exact same type as this (i.e. getClass().equals(getDefaultInstanceForType().getClass())).

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++.

Specified by:

mergeFrom in interface MessageLite.Builder

internalMergeFrom

protected abstract BuilderType internalMergeFrom(MessageType message)

newUninitializedMessageException

protected static UninitializedMessageException newUninitializedMessageException(MessageLite message)

Construct an UninitializedMessageException reporting missing fields in the given message.

addAll

@Deprecated
protected static <T> void addAll(Iterable<T> values,
                         Collection<? super T> list)

Deprecated.

addAll

protected static <T> void addAll(Iterable<T> values,
              List<? super T> list)

Adds the values to the list. This is a helper method used by generated code. Users should ignore it.

Throws:

NullPointerException - if values or any of the elements of values is null.
