A @code{gdb.Inferior} object has the following methods:

been populated with the new value and may be used in output. This
method must return a string. If the returned string is not empty,
@value{GDBN} will present it to the user.
+
+If this method raises the @code{gdb.GdbError} exception
+(@pxref{Exception Handling}), then @value{GDBN} will print the
+exception's string and the @code{set} command will fail. Note,
+however, that the @code{value} attribute will not be reset in this
+case. So, if your parameter must validate values, it should store the
+old value internally and reset the exposed value, like so:

One may add arbitrary attributes to @code{gdb.Progspace} objects
in the usual Python way.
This is useful if, for example, one needs to do some extra record keeping
@findex gdb.objfiles
