Method Detail

newInstance

Description copied from class: GeneratedMessageV3

Creates a new instance of this message type. Overridden in the generated code.

Overrides:

newInstance in class GeneratedMessageV3

getUnknownFields

public final UnknownFieldSet getUnknownFields()

Description copied from interface: MessageOrBuilder

Get the UnknownFieldSet for this message.

Specified by:

getUnknownFields in interface MessageOrBuilder

Overrides:

getUnknownFields in class GeneratedMessageV3

getDescriptor

public static final Descriptors.Descriptor getDescriptor()

internalGetFieldAccessorTable

protected GeneratedMessageV3.FieldAccessorTable internalGetFieldAccessorTable()

Description copied from class: GeneratedMessageV3

Get the FieldAccessorTable for this type. We can't have the message class pass this in to the constructor because of bootstrapping trouble with DescriptorProtos.

Specified by:

internalGetFieldAccessorTable in class GeneratedMessageV3

hasMessageSetWireFormat

public boolean hasMessageSetWireFormat()

 Set true to use the old proto1 MessageSet wire format for extensions.
 This is provided for backwards-compatibility with the MessageSet wire
 format.  You should not use this for any other reason:  It's less
 efficient, has fewer features, and is more complicated.
 The message must be defined exactly as follows:
   message Foo {
     option message_set_wire_format = true;
     extensions 4 to max;
   }
 Note that the message cannot have any defined fields; MessageSets only
 have extensions.
 All extensions of your type must be singular messages; e.g. they cannot
 be int32s, enums, or repeated messages.
 Because this is an option, the above two restrictions are not enforced by
 the protocol compiler.
 

optional bool message_set_wire_format = 1 [default = false];

Specified by:

hasMessageSetWireFormat in interface DescriptorProtos.MessageOptionsOrBuilder

getMessageSetWireFormat

public boolean getMessageSetWireFormat()

 Set true to use the old proto1 MessageSet wire format for extensions.
 This is provided for backwards-compatibility with the MessageSet wire
 format.  You should not use this for any other reason:  It's less
 efficient, has fewer features, and is more complicated.

hasNoStandardDescriptorAccessor

public boolean hasNoStandardDescriptorAccessor()

 Disables the generation of the standard "descriptor()" accessor, which can
 conflict with a field of the same name.  This is meant to make migration
 from proto1 easier; new code should avoid fields named "descriptor".
 

optional bool no_standard_descriptor_accessor = 2 [default = false];

Specified by:

hasNoStandardDescriptorAccessor in interface DescriptorProtos.MessageOptionsOrBuilder

getNoStandardDescriptorAccessor

public boolean getNoStandardDescriptorAccessor()

 Disables the generation of the standard "descriptor()" accessor, which can
 conflict with a field of the same name.  This is meant to make migration
 from proto1 easier; new code should avoid fields named "descriptor".
 

optional bool no_standard_descriptor_accessor = 2 [default = false];

hasDeprecated

public boolean hasDeprecated()

 Is this message deprecated?
 Depending on the target platform, this can emit Deprecated annotations
 for the message, or it will be completely ignored; in the very least,
 this is a formalization for deprecating messages.
 

optional bool deprecated = 3 [default = false];

optional bool deprecated = 3 [default = false];

Specified by:

hasMapEntry

public boolean hasMapEntry()

 Whether the message is an automatically generated map entry type for the
 maps field.
 For maps fields:
     map<KeyType, ValueType> map_field = 1;
 The parsed descriptor looks like:
     message MapFieldEntry {
         option map_entry = true;
         optional KeyType key = 1;
         optional ValueType value = 2;
     }
     repeated MapFieldEntry map_field = 1;
 Implementations may choose not to generate the map_entry=true message, but
 use a native map in the target language to hold the keys and values.
 The reflection APIs in such implementations still need to work as
 if the field is a repeated message field.
 NOTE: Do not set the option in .proto files. Always use the maps syntax
 instead. The option should only be implicitly set by the proto compiler
 parser.
 

optional bool map_entry = 7;

Specified by:

hasMapEntry in interface DescriptorProtos.MessageOptionsOrBuilder

getMapEntry

public boolean getMapEntry()

 Whether the message is an automatically generated map entry type for the
 maps field.
 For maps fields:
     map<KeyType, ValueType> map_field = 1;
 The parsed descriptor looks like:
     message MapFieldEntry {
         option map_entry = true;
         optional KeyType key = 1;
         optional ValueType value = 2;
     }
     repeated MapFieldEntry map_field = 1;
 Implementations may choose not to generate the map_entry=true message, but
 use a native map in the target language to hold the keys and values.
 The reflection APIs in such implementations still need to work as
 if the field is a repeated message field.
 NOTE: Do not set the option in .proto files. Always use the maps syntax

writeTo

public void writeTo(CodedOutputStream output)
             throws IOException

Description copied from interface: MessageLite

Serializes the message and writes it to output. This does not flush or close the stream.

Specified by:

writeTo in interface MessageLite

Overrides:

writeTo in class GeneratedMessageV3

Throws:

getSerializedSize

public int getSerializedSize()

Description copied from interface: MessageLite

Get the number of bytes required to encode this message. The result is only computed on the first call and memoized after that.

Specified by:

getSerializedSize in interface MessageLite

Overrides:

getSerializedSize in class GeneratedMessageV3

equals

public boolean equals(Object obj)

Description copied from interface: Message

Compares the specified object with this message for equality. Returns true if the given object is a message of the same type (as defined by getDescriptorForType()) and has identical values for all of its fields. Subclasses must implement this; inheriting Object.equals() is incorrect.

Specified by:

equals in interface Message

Overrides:

equals in class AbstractMessage

Parameters:

obj - object to be compared for equality with this message

Returns:

true if the specified object is equal to this message

hashCode

public int hashCode()

Description copied from interface: Message

Returns the hash code value for this message. The hash code of a message should mix the message's type (object identity of the descriptor) with its contents (known and unknown field values). Subclasses must implement this; inheriting Object.hashCode() is incorrect.

Specified by:

hashCode in interface Message

Overrides:

hashCode in class AbstractMessage

Returns:

the hash code value for this message

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.
