Class Acme.PostURLConnection

java.lang.Object
   |
   +----Acme.PostURLConnection

public class PostURLConnection

extends Object

Some implementations of URLConnection, e.g. the one in Navigator 3.0, do not support POST. This is a stripped-down version that does.

Note that it can't inherit from java.net.URLConnection because that class has no public constructors. Not all the standard URLConnection methods are re-implemented here, just the ones necessary for posting.

This class is not needed in current browsers.

close()

connect()

getContentLength()

getContentType()

Gets the content type.

getDoInput()

getDoOutput()

getHeaderField(String)

Gets a header field by name.

getHeaderFieldDate(String, long)

Gets a header field by name.

getHeaderFieldInt(String, int)

Gets a header field by name.

getInputStream()

Call this routine to get an InputStream that reads from the object.

getOutputStream()

Call this routine to get an OutputStream that writes to the object.

getRequestProperty(String)

getURL()

Gets the URL for this connection.

getUseCaches()

setDoInput(boolean)

A URL connection can be used for input and/or output.

setDoOutput(boolean)

A URL connection can be used for input and/or output.

setRequestProperty(String, String)

setUseCaches(boolean)

Some protocols do caching of documents.

toString()

Returns the String representation of the URL connection.

 public PostURLConnection(URL url)

Constructs a POST URL connection to the specified URL.

Parameters:

url - the specified URL

 public void connect() throws IOException

 public void close() throws IOException

 public URL getURL()

Gets the URL for this connection.

 public int getContentLength() throws IOException

 public String getContentType() throws IOException

Gets the content type. Returns null if not known.

 public String getHeaderField(String name) throws IOException

Gets a header field by name. Returns null if not known.

Parameters:

name - the name of the header field

 public int getHeaderFieldInt(String name,
                              int def) throws IOException

Gets a header field by name. Returns null if not known. The field is parsed as an integer.

Parameters:

name - the name of the header field

def - the value to return if the field is missing or malformed.

 public long getHeaderFieldDate(String name,
                                long def) throws IOException

Gets a header field by name. Returns null if not known. The field is parsed as a date.

Parameters:

name - the name of the header field

def - the value to return if the field is missing or malformed.

 public InputStream getInputStream() throws IOException

Call this routine to get an InputStream that reads from the object.

Throws: UnknownServiceException

If the protocol does not support input.

 public OutputStream getOutputStream() throws IOException

Call this routine to get an OutputStream that writes to the object.

Throws: UnknownServiceException

If the protocol does not support output.

 public String toString()

Returns the String representation of the URL connection.

Overrides:

toString in class Object

 public void setDoInput(boolean doInput)

A URL connection can be used for input and/or output. Set the DoInput flag to true if you intend to use the URL connection for input, false if not. The default for PostURLConnections is false.

 public boolean getDoInput()

 public void setDoOutput(boolean doOutput)

A URL connection can be used for input and/or output. Set the DoOutput flag to true if you intend to use the URL connection for output, false if not. The default for PostURLConnections is true.

 public boolean getDoOutput()

 public void setUseCaches(boolean useCaches)

Some protocols do caching of documents. Occasionally, it is important to be able to "tunnel through" and ignore the caches (e.g. the "reload" button in a browser). If the UseCaches flag on a connection is true, the connection is allowed to use whatever caches it can. If false, caches are to be ignored. The default for PostURLConnections is false.

 public boolean getUseCaches()

 public void setRequestProperty(String name,
                                String value)

 public String getRequestProperty(String name)
