// Class : GeomVertexRewriter
|
|
// Description : This object provides the functionality of both a
|
|
// GeomVertexReader and a GeomVertexWriter, combined
|
|
// together into one convenient package. It is designed
|
|
// for making a single pass over a GeomVertexData
|
|
// object, modifying rows as it goes.
|
|
//
|
|
// Although it doesn't provide any real performance
|
|
// benefit over using a separate reader and writer on
|
|
// the same data, it should probably be used in
|
|
// preference to a separate reader and writer, because
|
|
// it makes an effort to manage the reference counts
|
|
// properly between the reader and the writer to avoid
|
|
// accidentally dereferencing either array while
|
|
// recopying.
