<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>vtkConvertSelection converts an input selection from one type to another in the context of a data object being selected. The first input is the selection, while the second input is the data object that the selection relates to.</p>
<p>To create an instance of class vtkConvertSelection, simply invoke its constructor as follows </p>
<pre class="fragment"> obj = vtkConvertSelection
</pre> <h1><a class="anchor" id="Methods"></a>
Methods</h1>
<p>The class vtkConvertSelection has several methods that can be used. They are listed below. Note that the documentation is translated automatically from the VTK sources, and may not be completely intelligible. When in doubt, consult the VTK website. In the methods listed below, <code>obj</code> is an instance of the vtkConvertSelection class. </p>
<ul>
<li>
<code>string = obj.GetClassName ()</code> </li>
<li>
<code>int = obj.IsA (string name)</code> </li>
<li>
<code>vtkConvertSelection = obj.NewInstance ()</code> </li>
<li>
<code>vtkConvertSelection = obj.SafeDownCast (vtkObject o)</code> </li>
<li>
<code>obj.SetDataObjectConnection (vtkAlgorithmOutput in)</code> - A convenience method for setting the second input (i.e. the data object). </li>
<li>
<code>obj.SetInputFieldType (int )</code> - The input field type. If this is set to a number other than -1, ignores the input selection field type and instead assumes that all selection nodes have the field type specified. This should be one of the constants defined in vtkSelectionNode.h. Default is -1. </li>
<li>
<code>int = obj.GetInputFieldType ()</code> - The input field type. If this is set to a number other than -1, ignores the input selection field type and instead assumes that all selection nodes have the field type specified. This should be one of the constants defined in vtkSelectionNode.h. Default is -1. </li>
<li>
<code>obj.SetOutputType (int )</code> - The output selection content type. This should be one of the constants defined in vtkSelectionNode.h. </li>
<li>
<code>int = obj.GetOutputType ()</code> - The output selection content type. This should be one of the constants defined in vtkSelectionNode.h. </li>
<li>
<code>obj.SetArrayName (string )</code> - The output array name for value or threshold selections. </li>
<li>
<code>string = obj.GetArrayName ()</code> - The output array name for value or threshold selections. </li>
<li>
<code>obj.SetArrayNames (vtkStringArray )</code> - The output array names for value selection. </li>
<li>
<code>vtkStringArray = obj.GetArrayNames ()</code> - The output array names for value selection. </li>
<li>
<code>obj.AddArrayName (string )</code> - Convenience methods used by UI </li>
<li>
<code>obj.ClearArrayNames ()</code> - Convenience methods used by UI </li>
<li>
<code>obj.SetMatchAnyValues (bool )</code> - When on, creates a separate selection node for each array. Defaults to OFF. </li>
<li>
<code>bool = obj.GetMatchAnyValues ()</code> - When on, creates a separate selection node for each array. Defaults to OFF. </li>
<li>
<code>obj.MatchAnyValuesOn ()</code> - When on, creates a separate selection node for each array. Defaults to OFF. </li>
<li>
<code>obj.MatchAnyValuesOff ()</code> - When on, creates a separate selection node for each array. Defaults to OFF. </li>
