Detailed Description

A TiledStream allows you to write a blob of binary data to a JSON stream in an efficient manner. The data is buffered into uniform arrays which are output into a standard JSON array. The resulting data looks something like:

[ {options} tile1-data tile2-data ]

The tile-data is written as JSON string objects. You can read these yourself, or use the TiledStream in UT_JSONParser.

You should never write to the JSONWriter while the TiledStream is open.

An example of using this might be something like:

bool storeStream(UT_IStream &is)
{
 UT_JSONWriter::TiledStream     os(writer);
 char                           buffer[128];
 int                            nread;
 while ((nread = is.bread(buffer, 128)) > 0)
    if (!os.write(buffer, nread)) return false;
 return true;
}
