Aspect for drawing unipolar polyshapes that hold pins on exactly one side.<q ref="core.svg:Bipolar">Bipolar</q>(c) SAP AG 2003-2006. All rights reserved. Gets the shape's geometry constraints.Extends the geometry constraints structure by adding the following members <table class="BOTH"><tr><td class="H V">Name </td><td class=H>Description </td></tr><tr><td class=V>poleStart </td><td>The minimum distance to keep between a pole start and the first pin on that pole </td></tr><tr><td class=V>poleEnd </td><td>The minimum distance to keep between a pole end and the last pin on that pole </td></tr></table> <ul><li>A <i>pole</i> is a contiguous block of pins arranged on the same side. </li><li>In a unipolar shape there is exactly one pole, either an <i>input</i> or an <i>output</i> pole. </li></ul>
