Method Summary

Modifier and TypeMethod and Description
public void
connect()

Implements abstract java.net.URLConnection.connect.

Opens a communications link to the resource referenced by this URL, if such a connection has not already been established.

private synchronized ImageReader.Node
connectResourceNode()

Finds and caches the resource node associated with this URL and marks the connection as "connected".

public int
getContentLength()

Overrides sun.net.www.URLConnection.getContentLength.

Call this routine to get the content-length associated with this object.

public long
getContentLengthLong()

Overrides java.net.URLConnection.getContentLengthLong.

Returns the value of the content-length header field as a long.

public InputStream
getInputStream()

Overrides java.net.URLConnection.getInputStream.

Returns an input stream that reads from this open connection.

Method Detail

connectback to summary
public void connect() throws IOException

Implements abstract java.net.URLConnection.connect.

Doc from java.net.URLConnection.connect.

Opens a communications link to the resource referenced by this URL, if such a connection has not already been established.

If the connect method is called when the connection has already been opened (indicated by the connected field having the value true), the call is ignored.

URLConnection objects go through two phases: first they are created, then they are connected. After being created, and before being connected, various options can be specified (e.g., doInput and UseCaches). After connecting, it is an error to try to set them. Operations that depend on being connected, like getContentLength, will implicitly perform the connection, if necessary.

Annotations

Exceptions
IOException:
if an I/O error occurs while opening the connection.

public InputStream getInputStream() throws IOException

Overrides java.net.URLConnection.getInputStream.
