Package net.i2p.util

Class EepHead

java.lang.Object

net.i2p.util.EepGet

net.i2p.util.EepHead

public class EepHead
extends EepGet

This is a quick hack to get a working EepHead, primarily for the following usage:

 EepHead foo = new EepHead(...);
 if (foo.fetch()) {
     String lastmod = foo.getLastModified();
     if (lastmod != null) {
         parse the string...
         ...
     }
 }
 

Other use cases (command line, listeners, etc...) lightly- or un-tested. Note that this follows redirects! This may not be what you want or expect. Writing from scratch rather than extending EepGet would maybe have been less bloated memory-wise. This way gets us redirect handling, among other benefits.

Constructor Detail

EepHead

public EepHead(I2PAppContext ctx,
               String proxyHost,
               int proxyPort,
               int numRetries,
               String url)

Method Detail

main

public static void main(String[] args)

EepHead [-p 127.0.0.1:4444] [-n #retries] url This doesn't really do much since it doesn't register a listener. EepGet doesn't have a method to store and return all the headers, so just print out the ones we have methods for. Turn on logging to use it for a decent test.

doFetch

protected void doFetch(SocketTimeout timeout)
                throws IOException

return true if the URL was completely retrieved

Overrides:

doFetch in class EepGet

Parameters:

timeout - may be null

Throws:

IOException

getRequest

protected String getRequest()
                     throws IOException

Overrides:

getRequest in class EepGet

Throws:

IOException

getContentLength

public long getContentLength()

We don't decrement the variable (unlike in EepGet), so this is valid
