Protobuf type google.protobuf.FieldMask

 `FieldMask` represents a set of symbolic field paths, for example:
     paths: "f.a"
     paths: "f.b.d"
 Here `f` represents a field in some root message, `a` and `b`
 fields in the message found in `f`, and `d` a field found in the
 message in `f.b`.
 Field masks are used to specify a subset of fields that should be
 returned by a get operation or modified by an update operation.
 Field masks also have a custom JSON encoding (see below).
 # Field Masks in Projections
 When used in the context of a projection, a response message or
 sub-message is filtered by the API to only contain those fields as
 specified in the mask. For example, if the mask in the previous
 example is applied to a response message as follows:
     f {
       a : 22
       b {
         d : 1
         x : 2
       }
       y : 13
     }
     z: 8
 The result will not contain specific values for fields x,y and z
 (there value will be set to the default, and omitted in proto text
 output):
     f {
       a : 22
       b {
         d : 1
       }
     }
 A repeated field is not allowed except at the last position of a
 field mask.
 If a FieldMask object is not present in a get operation, the
 operation applies to all fields (as if a FieldMask of all fields
 had been specified).
 Note that a field mask does not necessarily applies to the
 top-level response message. In case of a REST get operation, the
 field mask applies directly to the response, but in case of a REST
 list operation, the mask instead applies to each individual message
 in the returned resource list. In case of a REST custom method,
 other definitions may be used. Where the mask applies will be
 clearly documented together with its declaration in the API.  In
 any case, the effect on the returned resource/resources is required
 behavior for APIs.
 # Field Masks in Update Operations
 A field mask in update operations specifies which fields of the
 targeted resource are going to be updated. The API is required
 to only change the values of the fields as specified in the mask
 and leave the others untouched. If a resource is passed in to
 describe the updated values, the API ignores the values of all
 fields not covered by the mask.
 In order to reset a field's value to the default, the field must
 be in the mask and set to the default value in the provided resource.
 Hence, in order to reset all fields of a resource, provide a default
 instance of the resource and set all fields in the mask, or do
 not provide a mask as described below.
 If a field mask is not present on update, the operation applies to
 all fields (as if a field mask of all fields has been specified).
 Note that in the presence of schema evolution, this may mean that
 fields the client does not know and has therefore not filled into
 the request will be reset to their default. If this is unwanted
 behavior, a specific service may require a client to always specify
 a field mask, producing an error if not.
 As with get operations, the location of the resource which
 describes the updated values in the request message depends on the
 operation kind. In any case, the effect of the field mask is
 required to be honored by the API.
 ## Considerations for HTTP REST
 The HTTP kind of an update operation which uses a field mask must
 be set to PATCH instead of PUT in order to satisfy HTTP semantics
 (PUT must only be used for full updates).
 # JSON Encoding of Field Masks
 In JSON, a field mask is encoded as a single string where paths are
 separated by a comma. Fields name in each path are converted
 to/from lower-camel naming conventions.
 As an example, consider the following message declarations:
     message Profile {
       User user = 1;
       Photo photo = 2;
     }
     message User {
       string display_name = 1;
       string address = 2;
     }
 In proto a field mask for `Profile` may look as such:
     mask {
       paths: "user.display_name"
       paths: "photo"
     }
 In JSON, the same mask is represented as below:
     {
       mask: "user.displayName,photo"
     }

  - getDefaultInstanceForType
```
public FieldMask 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.

```
    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. Subsequent changes to the Builder will not affect the returned message.

  - mergeFrom
```
public FieldMask.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. * For oneof groups, if the other message has one of the fields set, the group of this message is cleared and replaced by the field of the other message, so that the oneof constraint is preserved. This is equivalent to the Message::MergeFrom method in C++.

    Description copied from interface: MessageLite.Builder
    
    Like MessageLite.Builder.mergeFrom(CodedInputStream), but also parses extensions. The extensions that you want to be able to parse must be registered in extensionRegistry. Extensions not in the registry will be treated as unknown fields.
