Method Detail

clear

public DynamicMessage.Builder clear()

Description copied from interface: MessageLite.Builder

Resets all fields to their default values.

Specified by:

clear in interface Message.Builder

Specified by:

clear in interface MessageLite.Builder

Overrides:

clear in class AbstractMessage.Builder<DynamicMessage.Builder>

mergeFrom

public DynamicMessage.Builder mergeFrom(Message other)

Description copied from interface: Message.Builder

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

public DynamicMessage 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 Once this is called, the Builder is no longer valid, and calling any other method will result in undefined behavior and may throw a NullPointerException.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.

buildPartial

public DynamicMessage 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 Once this is called, the Builder is no longer valid, and calling any will result in undefined behavior and may throw a NullPointerException.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.

clone

public DynamicMessage.Builder clone()

Description copied from interface: MessageLite.Builder

Clones the Builder.

Specified by:

clone in interface Message.Builder

Specified by:

Specified by:

clone in class AbstractMessage.Builder<DynamicMessage.Builder>

Object.clone()

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.

getDescriptorForType

public Descriptors.Descriptor getDescriptorForType()

Description copied from interface: Message.Builder

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

getDefaultInstanceForType

public DynamicMessage getDefaultInstanceForType()

Description copied from interface: MessageLiteOrBuilder

Get an instance of the type with no fields set. Because no fields are set, all getters for singular fields will return default values and repeated fields will appear empty. This may or may not be a singleton. This differs from the getDefaultInstance() method of generated message classes in that this method is an abstract method of the MessageLite interface whereas getDefaultInstance() is a static method of a specific class. They return the same thing.

getAllFields

public Map<Descriptors.FieldDescriptor,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 getRepeatedFieldSize() 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 DynamicMessage.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().

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 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 returend. For embedded message fields, the sub-message is returned. For repeated fields, a java.util.List is returned.

setField

public DynamicMessage.Builder setField(Descriptors.FieldDescriptor field,
                              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 DynamicMessage.Builder 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.

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 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 returend. For embedded message fields, the sub-message is returned.

setRepeatedField

public DynamicMessage.Builder setRepeatedField(Descriptors.FieldDescriptor field,
                                      int index,
                                      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 DynamicMessage.Builder addRepeatedField(Descriptors.FieldDescriptor field,
                                      Object value)

Description copied from interface: Message.Builder

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

getUnknownFields

public UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.

setUnknownFields

public DynamicMessage.Builder setUnknownFields(UnknownFieldSet unknownFields)

Description copied from interface: Message.Builder

Set the UnknownFieldSet for this message.

mergeUnknownFields

public DynamicMessage.Builder 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<DynamicMessage.Builder>
