| <p> |
| Upon entry to the <code class="computeroutput"><span class="identifier">parse</span></code> |
| member function, a PrimitiveParser is required to do a pre-skip. Leading |
| <code class="computeroutput"><span class="identifier">skip</span></code> characters/tokens |
| will be skipped prior to parsing. Only PrimitiveParsers are required |
| to perform this pre-skip. This is typically carried out through a call |
| to <code class="computeroutput"><span class="identifier">qi</span><span class="special">::</span><span class="identifier">skip_over</span></code>: |
