InvalidSortSpecification class

An InvalidSortSpecification exception indicates that the first argument provided to either the Sort or SortNew method (in the Stringlist class) is not a valid sort specification.

This exception class has no properties. The class's only method is the New constructor, which you would typically use with a User Language Throw statement to produce an InvalidSortSpecification exception. For example:

throw %(invalidSortSpecification):new

Remember that catching an exception is done with the Catch statement; if an exception condition occurs outside a Catch for it, the request is cancelled.

In most cases, a sort specification is part of User Language code, and so should always be correct and request cancellation is an appropriate action. If, however, a sort specification can be entered at least in part by an end user, a Try/Catch block might be appropriate, as shown here:

try %strlist:sort(%sortSpec) catch invalidSortSpecification Print 'Invalid ...' ... end try

The InvalidSortSpecification class is available as of version 7.9.
