Connection (hazelcast-client-protocol 1.0.0 API)

All Known Implementing Classes:

TcpIpConnection
```
public interface Connection
```
Represents a 'connection' between two machines. The most important implementation is the TcpIpConnection.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`close()` Closes this connection.
`Address`	`getEndPoint()` Gets the `Address` of the other side of this Connection.
`InetAddress`	`getInetAddress()` Returns remote address of this Connection.
`int`	`getPort()` The remote port.
`InetSocketAddress`	`getRemoteSocketAddress()` Returns the address of the endpoint this Connection is connected to, or `null` if it is unconnected.
`ConnectionType`	`getType()` Returns the `ConnectionType` of this Connection.
`boolean`	`isAlive()` Checks if the Connection is alive.
`boolean`	`isClient()` Checks if it is a client connection.
`long`	`lastReadTimeMillis()` Returns the clock time in milliseconds of the most recent read using this connection.
`long`	`lastWriteTimeMillis()` Returns the clock time in milliseconds of the most recent write using this connection.
`void`	`setType(ConnectionType type)` Sets the type of the connection
`boolean`	`write(OutboundFrame frame)` Writes a outbound frame so it can be received by the other side of the connection.

- Method Detail
  - isAlive
```
boolean isAlive()
```
    Checks if the Connection is alive.
    
    Returns:
    true if alive, false otherwise.
  - lastReadTimeMillis
```
long lastReadTimeMillis()
```
    Returns the clock time in milliseconds of the most recent read using this connection.
    
    Returns:
    the clock time of the most recent read
  - lastWriteTimeMillis
```
long lastWriteTimeMillis()
```
    Returns the clock time in milliseconds of the most recent write using this connection.
    
    Returns:
    the clock time of the most recent write.
  - getType
```
ConnectionType getType()
```
    Returns the ConnectionType of this Connection.
    
    Returns:
    the ConnectionType. It could be that null is returned.
  - setType
```
void setType(ConnectionType type)
```
    Sets the type of the connection
    
    Parameters:
    type - to be set
  - isClient
```
boolean isClient()
```
    Checks if it is a client connection.
    
    Returns:
    true if client connection, false otherwise.
  - getInetAddress
```
InetAddress getInetAddress()
```
    Returns remote address of this Connection.
    
    Returns:
    the remote address. The returned value could be null if the connection is not alive.
  - getRemoteSocketAddress
```
InetSocketAddress getRemoteSocketAddress()
```
    Returns the address of the endpoint this Connection is connected to, or null if it is unconnected.
    
    Returns:
    address of the endpoint.
    todo: do we really need this method because we have getInetAddress, InetSocketAddress and getEndPoint.
  - getEndPoint
```
Address getEndPoint()
```
    Gets the Address of the other side of this Connection.
    todo: rename to get remoteAddress?
    
    Returns:
    the Address.
  - getPort
```
int getPort()
```
    The remote port.
    todo: rename to getRemotePort? And do we need it because we already have getEndPoint which returns an address which includes port. It is only used in testing
    
    Returns:
    the remote port number to which this Connection is connected, or 0 if the socket is not connected yet.
  - write
```
boolean write(OutboundFrame frame)
```
    Writes a outbound frame so it can be received by the other side of the connection. No guarantees are made that the frame is going to be received on the other side.
    The frame could be stored in an internal queue before it actually is written, so this call does not need to be a synchronous call.
    
    Parameters:
    frame - the frame to write.
    
    Returns:
    false if the frame was not accepted to be written, e.g. because the Connection was not alive.
    
    Throws:
    
    NullPointerException - if frame is null.
  - close
```
void close()
```
    Closes this connection.
    Pending packets on this connection are discarded
    If the Connection is already closed, the call is ignored. So it can safely be called multiple times.
