IPConnection

public IPConnection(String type,
 byte[] localAddress,
 int localPort,
 byte[] foreignAddress,
 int foreignPort,
 InternetProtocolStats.TcpState state,
 int transmitQueue,
 int receiveQueue,
 int owningProcessId)

Method Details

getType

public String getType()

Returns the connection protocol type, e.g., tcp4, tcp6, tcp46, udp4, udp6, udp46

Returns:

The protocol type

getLocalAddress

public byte[] getLocalAddress()

Gets the local address. For IPv4 addresses this is a 4-byte array. For IPv6 addresses this is a 16-byte array.

On Unix operating systems, the 16-bit value may be truncated, giving only the high order bytes. IPv6 addresses ending in zeroes should be considered suspect.

Returns:

The local address, or an empty array if the listener can accept a connection on any interface.

getLocalPort

public int getLocalPort()

Gets the local port.

Returns:

The local port, or 0 if unknown, or any port.

getForeignAddress

public byte[] getForeignAddress()

Gets the foreign/remote address. For IPv4 addresses this is a 4-byte array. For IPv6 addresses this is a 16-byte array.

On Unix operating systems, this value may be truncated. IPv6 addresses ending in zeroes should be considered suspect.

Returns:

The foreign/remote address, or an empty array if unknown. An empty array will also result if

getForeignPort

public int getForeignPort()

Gets the foreign/remote port.

Returns:

The foreign/remote port, or 0 if unknown.

getState

public InternetProtocolStats.TcpState getState()

Gets the connection state (TCP connections only).

Returns:

The connection state if known or relevant, null otherwise.

getTransmitQueue

public int getTransmitQueue()

Gets the size of the transmit queue. Not available on Windows.

Returns:

The size of the transmit queue, or 0 if unknown.

getReceiveQueue

public int getReceiveQueue()

Gets the size of the receive queue. Not available on Windows.

Returns:

The size of the receive queue, or 0 if unknown.

getowningProcessId

public int getowningProcessId()

Gets the id of the process which holds this connection.

Returns:

The process id of the process which holds this connection if known, -1 otherwise.

toString

public String toString()

Overrides:

toString in class Object
