public final class Struct
extends GeneratedMessageV3
implements StructOrBuilder

 `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 google.protobuf.Struct

public static final Descriptors.Descriptor getDescriptor()

  - internalGetMapField
```
protected MapField internalGetMapField(int number)
```
    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.

```
    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.

    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:

    Parameters:

  - 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:

public Struct 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.
