NO_PROXY

public static final Proxy NO_PROXY

A proxy setting that represents a DIRECT connection, basically telling the protocol handler not to use any proxying. Used, for instance, to create sockets bypassing any other global proxy settings (like SOCKS):

Socket s = new Socket(Proxy.NO_PROXY);

构造器详细资料

Proxy

public Proxy(Proxy.Type type,
             SocketAddress sa)

Creates an entry representing a PROXY connection. Certain combinations are illegal. For instance, for types Http, and Socks, a SocketAddress must be provided.

Use the Proxy.NO_PROXY constant for representing a direct connection.

参数:

type - the Type of the proxy

sa - the SocketAddress for that proxy

抛出:

IllegalArgumentException - when the type and the address are incompatible

方法详细资料

type

public Proxy.Type type()

Returns the proxy type.

返回:

a Type representing the proxy type

address

public SocketAddress address()

Returns the socket address of the proxy, or null if its a direct connection.

返回:

a SocketAddress representing the socket end point of the proxy

toString

public String toString()

Constructs a string representation of this Proxy. This String is constructed by calling toString() on its type and concatenating " @ " and the toString() result from its address if its type is not DIRECT.

覆盖:

toString 在类中 Object

返回:

a string representation of this object.

equals

public final boolean equals(Object obj)

Compares this object against the specified object. The result is true if and only if the argument is not null and it represents the same proxy as this object.

Two instances of Proxy represent the same address if both the SocketAddresses and type are equal.

覆盖:

equals 在类中 Object

参数:

obj - the object to compare against.

返回:

true if the objects are the same; false otherwise.

hashCode

public final int hashCode()

Returns a hashcode for this Proxy.

覆盖:

hashCode 在类中 Object

返回:

a hash code value for this Proxy.
