updateMask property

@TagNumber(3) DocumentMask get updateMask

The fields to update in this write.

This field can be set only when the operation is update. If the mask is not set for an update and the document exists, any existing data will be overwritten. If the mask is set and the document on the server has fields not covered by the mask, they are left unchanged. Fields referenced in the mask, but not present in the input document, are deleted from the document on the server. The field paths in this mask must not contain a reserved field name.

Implementation

@$pb.TagNumber(3)
$1.DocumentMask get updateMask => $_getN(2);

@TagNumber(3) set updateMask (DocumentMask v)

Implementation

@$pb.TagNumber(3)
set updateMask($1.DocumentMask v) {
  setField(3, v);
}
