Method Summary public  boolean canCache()      Returns true if the data associated with this URL can be cached. public  void close()      Call this to close the connection and flush any remaining data. public  int getContentLength()      Call this routine to get the content-length associated with this object. public  String getContentType()      Call this routine to get the content-type associated with this object. public  String getHeaderField(String name)      public  String getHeaderField(int n)      Return the value for the nth header field. public  String getHeaderFieldKey(int n)      Return the key for the nth header field. public  MessageHeader getProperties()      Call this routine to get the property list for this object. Properties (like content-type) that have explicit getXX() methods associated with them should be accessed using those methods. protected  void setContentLength(int length)      Call this routine to set the content-length associated with this object. public  void setContentType(String type)      Set the content type of this URL to a specific value. Parameters:   type - The content type to use. public  void setProperties(MessageHeader properties)      Call this routine to set the property list for this object. public  void setRequestProperty(String key, String value)      Field Detail properties protected MessageHeader properties(Code) Constructor Detail URLConnection public URLConnection(URL u)(Code) Create a URLConnection object. These should not be created directly: instead they should be created by protocol handers in response to URL.openConnection. Parameters:   u - The URL that this connects to. Method Detail canCache public boolean canCache()(Code) Returns true if the data associated with this URL can be cached. close public void close()(Code) Call this to close the connection and flush any remaining data. Overriders must remember to call super.close() getContentLength public int getContentLength()(Code) Call this routine to get the content-length associated with this object. getContentType public String getContentType()(Code) Call this routine to get the content-type associated with this object. getHeaderField public String getHeaderField(String name)(Code) getHeaderField public String getHeaderField(int n)(Code) Return the value for the nth header field. Returns null if there are fewer than n fields. This can be used in conjunction with getHeaderFieldKey to iterate through all the headers in the message. getHeaderFieldKey public String getHeaderFieldKey(int n)(Code) Return the key for the nth header field. Returns null if there are fewer than n fields. This can be used to iterate through all the headers in the message. getProperties public MessageHeader getProperties()(Code) Call this routine to get the property list for this object. Properties (like content-type) that have explicit getXX() methods associated with them should be accessed using those methods. setContentLength protected void setContentLength(int length)(Code) Call this routine to set the content-length associated with this object. setContentType public void setContentType(String type)(Code) Set the content type of this URL to a specific value. Parameters:   type - The content type to use. One of thecontent_* static variables in thisclass should be used.eg. setType(URL.content_html); setProperties public void setProperties(MessageHeader properties)(Code) Call this routine to set the property list for this object. setRequestProperty public void setRequestProperty(String key, String value)(Code) Fields inherited from java.net.URLConnection protected boolean allowUserInteraction(Code)(Java Doc) protected boolean connected(Code)(Java Doc) protected boolean doInput(Code)(Java Doc) protected boolean doOutput(Code)(Java Doc) protected long ifModifiedSince(Code)(Java Doc) protected URL url(Code)(Java Doc) protected boolean useCaches(Code)(Java Doc) Methods inherited from java.net.URLConnection public void addRequestProperty(String key, String value)(Code)(Java Doc) abstract public void connect() throws IOException(Code)(Java Doc) public boolean getAllowUserInteraction()(Code)(Java Doc) public Object getContent() throws IOException(Code)(Java Doc) public Object getContent(Class[] classes) throws IOException(Code)(Java Doc) public String getContentEncoding()(Code)(Java Doc) public int getContentLength()(Code)(Java Doc) public String getContentType()(Code)(Java Doc) public long getDate()(Code)(Java Doc) public static boolean getDefaultAllowUserInteraction()(Code)(Java Doc) public boolean getDefaultUseCaches()(Code)(Java Doc) public boolean getDoInput()(Code)(Java Doc) public boolean getDoOutput()(Code)(Java Doc) public long getExpiration()(Code)(Java Doc) public static synchronized FileNameMap getFileNameMap()(Code)(Java Doc) public String getHeaderField(String name)(Code)(Java Doc) public String getHeaderField(int n)(Code)(Java Doc) public long getHeaderFieldDate(String name, long Default)(Code)(Java Doc) public int getHeaderFieldInt(String name, int Default)(Code)(Java Doc) public String getHeaderFieldKey(int n)(Code)(Java Doc) public Map getHeaderFields()(Code)(Java Doc) public long getIfModifiedSince()(Code)(Java Doc) public InputStream getInputStream() throws IOException(Code)(Java Doc) public long getLastModified()(Code)(Java Doc) public OutputStream getOutputStream() throws IOException(Code)(Java Doc) public Permission getPermission() throws IOException(Code)(Java Doc) public Map getRequestProperties()(Code)(Java Doc) public String getRequestProperty(String key)(Code)(Java Doc) public URL getURL()(Code)(Java Doc) public boolean getUseCaches()(Code)(Java Doc) public static String guessContentTypeFromName(String fname)(Code)(Java Doc) public static String guessContentTypeFromStream(InputStream is) throws IOException(Code)(Java Doc) public void setAllowUserInteraction(boolean allowuserinteraction)(Code)(Java Doc) public static synchronized void setContentHandlerFactory(ContentHandlerFactory fac)(Code)(Java Doc) public static void setDefaultAllowUserInteraction(boolean defaultallowuserinteraction)(Code)(Java Doc) public void setDefaultUseCaches(boolean defaultusecaches)(Code)(Java Doc) public void setDoInput(boolean doinput)(Code)(Java Doc) public void setDoOutput(boolean dooutput)(Code)(Java Doc) public static void setFileNameMap(FileNameMap map)(Code)(Java Doc) public void setIfModifiedSince(long ifmodifiedsince)(Code)(Java Doc) public void setRequestProperty(String key, String value)(Code)(Java Doc) public void setUseCaches(boolean usecaches)(Code)(Java Doc) public String toString()(Code)(Java Doc) Methods inherited from java.lang.Object public boolean equals(Object obj)(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
