Scheme

extends Object
java.lang.Object
   ↳ org.apache.http.conn.scheme.Scheme

Class Overview

Encapsulates specifics of a protocol scheme such as "http" or "https". Schemes are identified by lowercase names. Supported schemes are typically collected in a SchemeRegistry.

For example, to configure support for "https://" URLs, you could write code like the following: 

 Scheme https = new Scheme("https", new MySecureSocketFactory(), 443);
 SchemeRegistry.DEFAULT.register(https);

Public Constructors

public Scheme (String name, SocketFactory factory, int port)

Added in API level 1

Creates a new scheme. Whether the created scheme allows for layered connections depends on the class of factory.

Parameters
name the scheme name, for example "http". The name will be converted to lowercase.
factory the factory for creating sockets for communication with this scheme
port the default port for this scheme

Public Methods

public final boolean equals (Object obj)

Added in API level 1

Compares this scheme to an object.

Parameters
obj the object to compare with
Returns
  • true iff the argument is equal to this scheme

public final int getDefaultPort ()

Added in API level 1

Obtains the default port.

Returns
  • the default port for this scheme

public final String getName ()

Added in API level 1

Obtains the scheme name.

Returns
  • the name of this scheme, in lowercase

public final SocketFactory getSocketFactory ()

Added in API level 1

Obtains the socket factory. If this scheme is layered, the factory implements LayeredSocketFactory.

Returns
  • the socket factory for this scheme

public int hashCode ()

Added in API level 1

Obtains a hash code for this scheme.

Returns
  • the hash code

public final boolean isLayered ()

Added in API level 1

Indicates whether this scheme allows for layered connections.

Returns
  • true if layered connections are possible, false otherwise

public final int resolvePort (int port)

Added in API level 1

Resolves the correct port for this scheme. Returns the given port if it is valid, the default port otherwise.

Parameters
port the port to be resolved, a negative number to obtain the default port
Returns
  • the given port or the defaultPort

public final String toString ()

Added in API level 1

Return a string representation of this object.

Returns
  • a human-readable string description of this scheme
