`Struct` represents a structured data value, consisting of fields which map to dynamically typed values. In some languages, `Struct` might be supported by a native representation. For example, in scripting languages like JS a struct is represented as an object. The details of that representation are described together with the proto support for the language. The JSON representation for `Struct` is JSON object.Protobuf type

Method Details
-
newInstance
Description copied from class:GeneratedMessageV3
Creates a new instance of this message type. Overridden in the generated code.- Overrides:
newInstance
in classGeneratedMessageV3
-
getUnknownFields
Description copied from interface:MessageOrBuilder
Get theUnknownFieldSet
for this message.- Specified by:
getUnknownFields
in interfaceMessageOrBuilder
- Overrides:
getUnknownFields
in classGeneratedMessageV3
-
getDescriptor
-
internalGetMapField
Description copied from class:GeneratedMessageV3
Gets the map field with the given field number. This method should be overridden in the generated message class if the message contains map fields.Unlike other field types, reflection support for map fields can't be implemented based on generated public API because we need to access a map field as a list in reflection API but the generated API only allows us to access it as a map. This method returns the underlying map field directly and thus enables us to access the map field as a list.
- Overrides:
internalGetMapField
in classGeneratedMessageV3
-
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 classGeneratedMessageV3
-
internalGetFields
-
getFieldsCount
public int getFieldsCount()Description copied from interface:StructOrBuilder
Unordered map of dynamically typed values.
map<string, .google.protobuf.Value> fields = 1;
- Specified by:

in interfaceStructOrBuilder
-
containsFields
Unordered map of dynamically typed values.
map<string, .google.protobuf.Value> fields = 1;
- Specified by:
containsFields

-
getFields
Deprecated.UsegetFieldsMap()
instead.- Specified by:

-
getFieldsMap
Unordered map of dynamically typed values.
map<string, .google.protobuf.Value> fields = 1;
- Specified by:
getFieldsMap
in interfaceStructOrBuilder
-
getFieldsOrDefault
Unordered map of dynamically typed values.
map<string, .google.protobuf.Value> fields = 1;
- Specified by:
getFieldsOrDefault
in interfaceStructOrBuilder
-
getFieldsOrThrow
Unordered map of dynamically typed values.
map<string, .google.protobuf.Value> fields = 1;
- Specified by:
getFieldsOrThrow
in interfaceStructOrBuilder
-
isInitialized
public final boolean isInitialized()Description copied from interface:MessageLiteOrBuilder
Returns true if all required fields in the message and all embedded messages are set, false otherwise.- Specified by:
isInitialized
in interfaceMessageLiteOrBuilder
- Overrides:
isInitialized
in classGeneratedMessageV3
-
writeTo
Description copied from interface:MessageLite
Serializes the message and writes it tooutput
. This does not flush or close the stream.- Specified by:
writeTo
in interfaceMessageLite
- Overrides:
writeTo
in classGeneratedMessageV3
- Throws:
IOException
-
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. If this message requires more than Integer.MAX_VALUE bytes to encode, the return value will be smaller than the actual number of bytes required and might be negative.- Specified by:
getSerializedSize
in interfaceMessageLite
- Overrides:
getSerializedSize
in classGeneratedMessageV3
-
equals
Description copied from interface:Message
Compares the specified object with this message for equality. Returnstrue
if the given object is a message of the same type (as defined bygetDescriptorForType()
) and has identical values for all of its fields. Subclasses must implement this; inheritingObject.equals()
is incorrect.- Specified by:
equals
in interfaceMessage
- Overrides:
equals
in classAbstractMessage
- 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; inheritingObject.hashCode()
is incorrect.- Specified by:
hashCode
in interfaceMessage
- Overrides:
hashCode
in classAbstractMessage
- Returns:
- the hash code value for this message

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 thegetDefaultInstance()
method of generated message classes in that this method is an abstract method of theMessageLite
interface whereasgetDefaultInstance()
is a static method of a specific class. They return the same thing.- Specified by:
