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.
* 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++.

build

Message build()

Description copied from interface: MessageLite.Builder

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

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. Subsequent changes to the Builder will not affect the returned message.

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.

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.

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 MessageOrBuilder.getDescriptorForType().

Specified by:

getDescriptorForType in interface MessageOrBuilder

newBuilderForField

Message.Builder newBuilderForField(Descriptors.FieldDescriptor field)

Create a builder for messages of the appropriate type for the given field. The builder is NOT nested in the current builder. However, messages built with the builder can then be passed to the setField(Descriptors.FieldDescriptor, Object), setRepeatedField(Descriptors.FieldDescriptor, int, Object), or addRepeatedField(Descriptors.FieldDescriptor, Object) method of the current builder.

To obtain a builder nested in the current builder, use getFieldBuilder(Descriptors.FieldDescriptor) instead.

getFieldBuilder

Message.Builder getFieldBuilder(Descriptors.FieldDescriptor field)

Get a nested builder instance for the given field.

Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.

If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.

NOTE: implementations that do not support nested builders will throw UnsupportedOperationException.

getRepeatedFieldBuilder

Message.Builder getRepeatedFieldBuilder(Descriptors.FieldDescriptor field,
                                        int index)

Get a nested builder instance for the given repeated field instance.

Normally, we hold a reference to the immutable message object for the message type field. Some implementations(the generated message builders), however, can also hold a reference to the builder object (a nested builder) for the field.

If the field is already backed up by a nested builder, the nested builder will be returned. Otherwise, a new field builder will be created and returned. The original message field (if exist) will be merged into the field builder, which will then be nested into its parent builder.

NOTE: implementations that do not support nested builders will throw UnsupportedOperationException.

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 MessageOrBuilder.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.

clearOneof

Message.Builder clearOneof(Descriptors.OneofDescriptor oneof)

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

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 MessageOrBuilder.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().

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(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

Message.Builder mergeFrom(java.io.InputStream input,
                          ExtensionRegistryLite extensionRegistry)

Returns:

this

Throws:

java.io.IOException

mergeDelimitedFrom

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

mergeDelimitedFrom

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