David,
The universally useful & and | operators.
in vertexFormat = foo.getVertexFormat();
if( (vertexFormat & GeometryArray.BY_REFERENCE) ==
GeometryArray.BY_REFERENCE)
{
// yep, the bit is set...
}
Sincerely,

Subject: How do I...
..query a GeometryArrayobject to find out if it is BY_REFERENCE or not?
I thought getVertexFormat() should work but the vertex format is input as a
bitmask i.e.
GeometryArray.COORDINATES | GeometryArray.NORMALS |
GeometryArray.BY_REFERENCE
How can I get just the BY_REFERENCE bit?
David
