Method Detail

clear

Message.Builder clear()

Description copied from interface: MessageLite.Builder

Resets all fields to their default values.

Specified by:

clear in interface MessageLite.Builder

mergeFrom

Message.Builder mergeFrom(Message other)

Merge other into the message being built. other must have the exact same type as this (i.e. getDescriptorForType() == other.getDescriptorForType()). 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. This is equivalent to the Message::MergeFrom method in C++.

build

Message build()

Description copied from interface: MessageLite.Builder

Construct the final message. Once this is called, the Builder is no longer valid, and calling any other method will result in undefined behavior and may throw a NullPointerException. If you need to continue working with the builder after calling build(), clone() it first.

Specified by:

build in interface MessageLite.Builder

buildPartial

Message buildPartial()

Description copied from interface: MessageLite.Builder

Like MessageLite.Builder.build(), but does not throw an exception if the message is missing required fields. Instead, a partial message is returned. Once this is called, the Builder is no longer valid, and calling any will result in undefined behavior and may throw a NullPointerException. If you need to continue working with the builder after calling buildPartial(), clone() it first.

Specified by:

buildPartial in interface MessageLite.Builder

clone

Message.Builder clone()

Description copied from interface: MessageLite.Builder

Clones the Builder.

Specified by:

clone in interface MessageLite.Builder

See Also:

Object.clone()

mergeFrom

Message.Builder 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, as if using Builder#mergeFrom(MessageLite).

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 MessageLite.Builder.isInitialized() to verify that all required fields are set before building.
• Parse the message separately using one of the static parseFrom methods, then use #mergeFrom(MessageLite) to merge it with this one. parseFrom will throw an InvalidProtocolBufferException (an IOException) if some required fields are missing.
• 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.

Specified by:

mergeFrom in interface MessageLite.Builder

Throws:

java.io.IOException

mergeFrom

Message.Builder 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

getDescriptorForType

Descriptors.Descriptor getDescriptorForType()

Get the message's type's descriptor. See Message.getDescriptorForType().

getDefaultInstanceForType

Message getDefaultInstanceForType()

Description copied from interface: MessageLite.Builder

Get the message's type's default instance. See MessageLite.getDefaultInstanceForType().

Specified by:

getDefaultInstanceForType in interface MessageLite.Builder

getAllFields

java.util.Map<Descriptors.FieldDescriptor,java.lang.Object> getAllFields()

Like Message.getAllFields(). The returned map may or may not reflect future changes to the builder. Either way, the returned map is itself unmodifiable.

newBuilderForField

Message.Builder newBuilderForField(Descriptors.FieldDescriptor field)

Create a Builder for messages of the appropriate type for the given field. Messages built with this can then be passed to setField(), setRepeatedField(), or addRepeatedField().

hasField

boolean hasField(Descriptors.FieldDescriptor field)

Like Message.hasField(Descriptors.FieldDescriptor)

getField

java.lang.Object getField(Descriptors.FieldDescriptor field)

Like Message.getField(Descriptors.FieldDescriptor)

setField

Message.Builder setField(Descriptors.FieldDescriptor field,
                         java.lang.Object value)

Sets a field to the given value. The value must be of the correct type for this field, i.e. the same type that Message.getField(Descriptors.FieldDescriptor) would return.

clearField

Message.Builder clearField(Descriptors.FieldDescriptor field)

Clears the field. This is exactly equivalent to calling the generated "clear" accessor method corresponding to the field.

getRepeatedFieldCount

int getRepeatedFieldCount(Descriptors.FieldDescriptor field)

Like Message.getRepeatedFieldCount(Descriptors.FieldDescriptor)

getRepeatedField

java.lang.Object getRepeatedField(Descriptors.FieldDescriptor field,
                                  int index)

Like Message.getRepeatedField(Descriptors.FieldDescriptor,int)

setRepeatedField

Message.Builder setRepeatedField(Descriptors.FieldDescriptor field,
                                 int index,
                                 java.lang.Object value)

Sets an element of a repeated field to the given value. The value must be of the correct type for this field, i.e. the same type that Message.getRepeatedField(Descriptors.FieldDescriptor,int) would return.

Throws:

java.lang.IllegalArgumentException - The field is not a repeated field, or field.getContainingType() != getDescriptorForType().

addRepeatedField

Message.Builder addRepeatedField(Descriptors.FieldDescriptor field,
                                 java.lang.Object value)

Like setRepeatedField, but appends the value as a new element.

Throws:

java.lang.IllegalArgumentException - The field is not a repeated field, or field.getContainingType() != getDescriptorForType().

getUnknownFields

UnknownFieldSet getUnknownFields()

Get the UnknownFieldSet for this message.

setUnknownFields

Message.Builder setUnknownFields(UnknownFieldSet unknownFields)

Set the UnknownFieldSet for this message.

mergeUnknownFields

Message.Builder mergeUnknownFields(UnknownFieldSet unknownFields)

Merge some unknown fields into the UnknownFieldSet for this message.

mergeFrom

Message.Builder 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:

Throws:

InvalidProtocolBufferException

mergeFrom

Message.Builder mergeFrom(ByteString data,
                          ExtensionRegistryLite extensionRegistry)

mergeFrom

Message.Builder 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.

                                   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

Throws:

java.io.IOException
