+Class
+    Foam::functionObjects::writeLocalObjects
+
+Description
+    FunctionObject base class for managing a list of objects on behalf of the
+    inheriting function object, on when those should be written to disk.
+
+    FunctionObjects that inherit this class will receive the additional
+    dictionary option \c objects which allows selecting which fields of the
+    inherited function should be written to disk when \c write() is called.
+    When \c objects is omitted, it will write all objects and when that list is
+    empty, it will not write any of the inheriting function object's managed
+    objects.
+
+    Example of function object specification:
+    \verbatim
+    <functionObjectName>
+    {
+        ...
+        objects     (obj1 obj2);
+        ...
+    }
+    \endverbatim
+
+Usage
+    \table
+        Property | Description                       | Required | Default value
+        objects  | List of objects to be written     | no       | ".*"
+    \endtable
+
+    Note: Regular expressions can also be used in \c objects.

+Class
+    Foam::functionObjects::writeObjectsBase
+
+Description
+    FunctionObject base class for writing a list of objects registered to the
+    database, on behalf of the inheriting function object, on when those should
+    be written to disk.
+
+    FunctionObjects that inherit this class will receive the additional
+    dictionary option \c objects which allows selecting which fields of the
+    inherited function should be written to disk when \c write() is called.
+
+    Example of function object specification:
+    \verbatim
+    <functionObjectName>
+    {
+        ...
+        objects     (obj1 obj2);
+        ...
+    }
+    \endverbatim
+
+Usage
+    \table
+        Property | Description                       | Required | Default value
+        objects  | List of objects to be written     | yes      |
+    \endtable
+
+    Note: Regular expressions can also be used in \c objects.
