Class HeaderInputStream

java.lang.Object
  java.io.InputStream
      java.io.FilterInputStream
          opendap.dap.HeaderInputStream

All Implemented Interfaces:

java.io.Closeable

public class HeaderInputStream
extends java.io.FilterInputStream

The HeaderInputStream filters the input to only read lines of text until the "Data:" line. This is required because overzealous buffering in the DDSParser will read the data as well as the DDS otherwise.
