Class SerialWriter

java.lang.Object

dap4.servlet.SerialWriter

public class SerialWriter
extends java.lang.Object

The SerialWriter class is intended to provide the API through which various kinds of data are written into the ChunkWriter.

Ideally, this class should be completely independent of CDM code so that Non-NetcdfDataset writers can be accomodated.
