Uses of URLConnection in java.net

Subclasses of URLConnection in java.net

class HttpURLConnection
A URLConnection with support for HTTP-specific features.

class JarURLConnection
A URL Connection to a Java ARchive (JAR) file or an entry in a JAR file.

Subclasses of URLConnection in java.net
`class`	`HttpURLConnection` A URLConnection with support for HTTP-specific features.
`class`	`JarURLConnection` A URL Connection to a Java ARchive (JAR) file or an entry in a JAR file.

Fields in java.net declared as URLConnection

protected URLConnection JarURLConnection.jarFileURLConnection
The connection to the JAR file URL, if the connection has been initiated.

Fields in java.net declared as URLConnection
`protected URLConnection`	`JarURLConnection.jarFileURLConnection` The connection to the JAR file URL, if the connection has been initiated.

Methods in java.net that return URLConnection

URLConnection URL.openConnection()
          Returns a URLConnection object that represents a connection to the remote object referred to by the URL.

URLConnection URL.openConnection(Proxy proxy)
          Same as openConnection(), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxing will ignore the proxy parameter and make a normal connection.

protected abstract URLConnection URLStreamHandler.openConnection(URL u)
          Opens a connection to the object referenced by the URL argument.

protected URLConnection URLStreamHandler.openConnection(URL u, Proxy p)
          Same as openConnection(URL), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxying will ignore the proxy parameter and make a normal connection.

Methods in java.net that return URLConnection
`URLConnection`	`URL.openConnection()` Returns a `URLConnection` object that represents a connection to the remote object referred to by the `URL`.
`URLConnection`	`URL.openConnection(Proxy proxy)` Same as openConnection(), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxing will ignore the proxy parameter and make a normal connection.
`protected abstract URLConnection`	`URLStreamHandler.openConnection(URL u)` Opens a connection to the object referenced by the `URL` argument.
`protected URLConnection`	`URLStreamHandler.openConnection(URL u, Proxy p)` Same as openConnection(URL), except that the connection will be made through the specified proxy; Protocol handlers that do not support proxying will ignore the proxy parameter and make a normal connection.

Methods in java.net with parameters of type URLConnection

abstract Object ContentHandler.getContent(URLConnection urlc)
          Given a URL connect stream positioned at the beginning of the representation of an object, this method reads that stream and creates an object from it.

Object ContentHandler.getContent(URLConnection urlc, Class[] classes)
          Given a URL connect stream positioned at the beginning of the representation of an object, this method reads that stream and creates an object that matches one of the types specified.

abstract CacheRequest ResponseCache.put(URI uri, URLConnection conn)
          The protocol handler calls this method after a resource has been retrieved, and the ResponseCache must decide whether or not to store the resource in its cache.

Methods in java.net with parameters of type URLConnection
`abstract Object`	`ContentHandler.getContent(URLConnection urlc)` Given a URL connect stream positioned at the beginning of the representation of an object, this method reads that stream and creates an object from it.
`Object`	`ContentHandler.getContent(URLConnection urlc, Class[] classes)` Given a URL connect stream positioned at the beginning of the representation of an object, this method reads that stream and creates an object that matches one of the types specified.
`abstract CacheRequest`	`ResponseCache.put(URI uri, URLConnection conn)` The protocol handler calls this method after a resource has been retrieved, and the ResponseCache must decide whether or not to store the resource in its cache.

Uses of URLConnection in javax.net.ssl

Subclasses of URLConnection in javax.net.ssl

class HttpsURLConnection
HttpsURLConnection extends HttpURLConnection with support for https-specific features.

Subclasses of URLConnection in javax.net.ssl
`class`	`HttpsURLConnection` `HttpsURLConnection` extends `HttpURLConnection` with support for https-specific features.
