Void input filter, which returns -1 when attempting a read. Used with a GET, HEAD, or a similar request.

 public class VoidInputFilter implements InputFilter {
 
 
     // -------------------------------------------------------------- Constants
 
 
     protected static final String ENCODING_NAME = "void";
     protected static final ByteChunk ENCODING = new ByteChunk();
 
 
     // ----------------------------------------------------- Static Initializer
 
 
     static {

Write some bytes.

Returns:
number of bytes written by the filter
 
     public int doRead(ByteChunk chunkRequest req)
         throws IOException {
 
         return -1;
 
     }
 
 
     // --------------------------------------------------- OutputFilter Methods
 

    
Set the associated reauest.
 
     public void setRequest(Request request) {
     }


    
Set the next buffer in the filter pipeline.
 
     public void setBuffer(InputBuffer buffer) {
     }


    
Make the filter ready to process the next request.
 
     public void recycle() {
     }


    
Return the name of the associated encoding; Here, the value is "void".
 
     public ByteChunk getEncodingName() {
        return ;
    }


    
End the current request. It is acceptable to write extra bytes using buffer.doWrite during the execution of this method.

Returns:
Should return 0 unless the filter does some content length delimitation, in which case the number is the amount of extra bytes or missing bytes, which would indicate an error. Note: It is recommended that extra bytes be swallowed by the filter.
    public long end()
        throws IOException {
        return 0;
    }


    
Amount of bytes still available in a buffer.
    public int available() {
        return 0;
    }
