HeaderInputStream (opendap 5.5.0 API)

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

All Implemented Interfaces:

Closeable, AutoCloseable
```
public class HeaderInputStream
extends 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.

- Method Detail
  - available
```
public int available()
```
    Return the number of bytes in the buffer.
    
    Overrides:
    
    available in class FilterInputStream
  - markSupported
```
public boolean markSupported()
```
    Returns that we don't support the mark() and reset() methods.
    
    Overrides:
    
    markSupported in class FilterInputStream
  - read
```
public int read()
         throws IOException
```
    Reads a single byte of data
    
    Overrides:
    
    read in class FilterInputStream
    
    Throws:
    
    IOException
  - read
```
public int read(byte[] b,
                int off,
                int len)
         throws IOException
```
    Reads up to len bytes of data from this input stream into an array of bytes. This method blocks until some input is available.
    
    Overrides:
    
    read in class FilterInputStream
    
    Throws:
    
    IOException
  - skip
```
