works around type-checking limitations
<p>
<a class="el" href="a00239.html" title="works around type-checking limitations">vtkCastToConcrete</a> is a filter that works around type-checking limitations in the filter classes. Some filters generate abstract types on output, and cannot be connected to the input of filters requiring a concrete input type. For example, <a class="el" href="a00455.html" title="generate scalars along a specified direction">vtkElevationFilter</a> generates <a class="el" href="a00374.html" title="abstract class to specify dataset behavior">vtkDataSet</a> for output, and cannot be connected to vtkDecimate, because vtkDecimate requires <a class="el" href="a01260.html" title="concrete dataset represents vertices, lines, polygons, and triangle strips">vtkPolyData</a> as input. This is true even though (in this example) the input to <a class="el" href="a00455.html" title="generate scalars along a specified direction">vtkElevationFilter</a> is of type <a class="el" href="a01260.html" title="concrete dataset represents vertices, lines, polygons, and triangle strips">vtkPolyData</a>, and you know the output of <a class="el" href="a00455.html" title="generate scalars along a specified direction">vtkElevationFilter</a> is the same type as its input.<p>
<a class="el" href="a00239.html" title="works around type-checking limitations">vtkCastToConcrete</a> performs run-time checking to insure that output type is of the right type. An error message will result if you try to cast an input type improperly. Otherwise, the filter performs the appropriate cast and returns the data.<p>
<dl class="warning" compact><dt><b>Warning:</b></dt><dd>You must specify the input before you can get the output. Otherwise an error results.</dd></dl>
