Method Detail

clone

public BuilderType clone()

Description copied from interface: MessageLite.Builder

Clones the Builder.

Specified by:

clone in interface Message.Builder

Specified by:

clone in interface MessageLite.Builder

Specified by:

clone in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

Object.clone()

clear

public BuilderType clear()

Called by the initialization and clear code paths to allow subclasses to reset any of their builtin fields back to the initial values.

Specified by:

clear in interface Message.Builder

Specified by:

clear in interface MessageLite.Builder

Overrides:

clear in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: Message.Builder

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

getAllFields

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

Description copied from interface: MessageOrBuilder

Returns a collection of all the fields in this message which are set and their corresponding values. A singular ("required" or "optional") field is set iff hasField() returns true for that field. A "repeated" field is set iff getRepeatedFieldCount() is greater than zero. The values are exactly what would be returned by calling MessageOrBuilder.getField(Descriptors.FieldDescriptor) for each field. The map is guaranteed to be a sorted map, so iterating over it will return fields in order by field number.
If this is for a builder, the returned map may or may not reflect future changes to the builder. Either way, the returned map is itself unmodifiable.

newBuilderForField

public Message.Builder newBuilderForField(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

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().

getFieldBuilder

public Message.Builder getFieldBuilder(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

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.

Specified by:

getFieldBuilder in interface Message.Builder

Overrides:

getFieldBuilder in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

getRepeatedFieldBuilder

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

Description copied from interface: Message.Builder

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.

hasOneof

public boolean hasOneof(Descriptors.OneofDescriptor oneof)

Description copied from class: AbstractMessage.Builder

TODO(jieluo): Clear it when all subclasses have implemented this method.

Specified by:

hasOneof in interface MessageOrBuilder

Overrides:

hasOneof in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

getOneofFieldDescriptor

public Descriptors.FieldDescriptor getOneofFieldDescriptor(Descriptors.OneofDescriptor oneof)

Description copied from class: AbstractMessage.Builder

TODO(jieluo): Clear it when all subclasses have implemented this method.

Specified by:

getOneofFieldDescriptor in interface MessageOrBuilder

Overrides:

getOneofFieldDescriptor in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

hasField

public boolean hasField(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Returns true if the given field is set. This is exactly equivalent to calling the generated "has" accessor method corresponding to the field.

getField

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

Description copied from interface: MessageOrBuilder

Obtains the value of the given field, or the default value if it is not set. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned. For repeated fields, a java.util.List is returned.

setField

public BuilderType setField(Descriptors.FieldDescriptor field,
                            java.lang.Object value)

Description copied from interface: Message.Builder

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

public BuilderType clearField(Descriptors.FieldDescriptor field)

Description copied from interface: Message.Builder

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

clearOneof

public BuilderType clearOneof(Descriptors.OneofDescriptor oneof)

Description copied from class: AbstractMessage.Builder

TODO(jieluo): Clear it when all subclasses have implemented this method.

Specified by:

clearOneof in interface Message.Builder

Overrides:

clearOneof in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

getRepeatedFieldCount

public int getRepeatedFieldCount(Descriptors.FieldDescriptor field)

Description copied from interface: MessageOrBuilder

Gets the number of elements of a repeated field. This is exactly equivalent to calling the generated "Count" accessor method corresponding to the field.

getRepeatedField

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

Description copied from interface: MessageOrBuilder

Gets an element of a repeated field. For primitive fields, the boxed primitive value is returned. For enum fields, the EnumValueDescriptor for the value is returned. For embedded message fields, the sub-message is returned.

setRepeatedField

public BuilderType setRepeatedField(Descriptors.FieldDescriptor field,
                                    int index,
                                    java.lang.Object value)

Description copied from interface: Message.Builder

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.

addRepeatedField

public BuilderType addRepeatedField(Descriptors.FieldDescriptor field,
                                    java.lang.Object value)

Description copied from interface: Message.Builder

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

setUnknownFields

public BuilderType setUnknownFields(UnknownFieldSet unknownFields)

Description copied from interface: Message.Builder

Set the UnknownFieldSet for this message.

mergeUnknownFields

public BuilderType mergeUnknownFields(UnknownFieldSet unknownFields)

Description copied from interface: Message.Builder

Merge some unknown fields into the UnknownFieldSet for this message.

Specified by:

mergeUnknownFields in interface Message.Builder

Overrides:

mergeUnknownFields in class AbstractMessage.Builder<BuilderType extends GeneratedMessage.Builder>

isInitialized

public boolean isInitialized()

Description copied from interface: MessageLiteOrBuilder

Returns true if all required fields in the message and all embedded messages are set, false otherwise.

See also: MessageOrBuilder.getInitializationErrorString()

getUnknownFields

public final UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.
