<p>The class <code>bad_expression</code> defines the type of objects thrown as
|
|
|
|
|
|
exceptions to report errors during the conversion from a string representing a
|
|
|
|
|
|
regular expression to a finite state machine. </p>

<h3>Description</h3>

|
|
<pre>
|
|
|
|

bad_expression(const string& what_arg);

|
|
|
|
<p><b>Effects:</b> Constructs an object of class <code>bad_expression</code>.</p>
|
|
|
|
|
|
<b></b>
|
|
|
|
|
|
<p><b>Postcondition:</b> <code>strcmp(what(), what_arg.c_str()) == 0</code>.</p>
|
|
|
|
|
|
<p>Footnotes: the class <i>bad_pattern</i> forms the base class for all
|
|
|
|
|
|
pattern-matching exceptions, of which <i>bad_expression</i> is one. The choice
|
|
|
|
|
|
of <i>std::runtime_error</i> as the base class for <i>bad_pattern</i> is moot;
|
|
|
|
|
|
depending upon how the library is used exceptions may be either logic errors
|
|
|
|
|
|
(programmer supplied expressions) or run time errors (user supplied
|
|
|
|
|
|
expressions).</p>
