    • getFieldsCount

      Description copied from interface: DocumentOrBuilder
       The document's fields.

 The map keys represent field names.

 Field names matching the regular expression `__.*__` are reserved. Reserved
 field names are forbidden except in certain documented contexts. The field
 names, represented as UTF-8, must not exceed 1,500 bytes and cannot be
 empty.

 Field paths may be used in other contexts to refer to structured fields
 defined here. For `map_value`, the field path is represented by a
 dot-delimited (`.`) string of segments. Each segment is either a simple
 field name (defined below) or a quoted field name. For example, the
 structured field `"foo" : { map_value: { "x&y" : { string_value: "hello"
 }}}` would be represented by the field path `` foo.`x&y` ``.

 A simple field name contains only characters `a` to `z`, `A` to `Z`,
 `0` to `9`, or `_`, and must not start with `0` to `9`. For example,
 `foo_bar_17`.

 A quoted field name starts and ends with `` ` `` and
 may contain any character. Some characters, including `` ` ``, must be
 escaped using a `\`. For example, `` `x&y` `` represents `x&y` and
 `` `bak\`tik` `` represents `` bak`tik ``.
