Method Detail

canConnectToSocket

public static boolean canConnectToSocket(java.lang.String host,
                                         int port)

getLoopbackAddress

@Deprecated
public static java.net.InetAddress getLoopbackAddress()

Deprecated. use InetAddress.getLoopbackAddress()

isLocalhost

public static boolean isLocalhost(java.lang.String hostName)

canConnectToRemoteSocket

public static boolean canConnectToRemoteSocket(java.lang.String host,
                                               int port)

findAvailableSocketPort

public static int findAvailableSocketPort()
                                   throws java.io.IOException

Throws:

java.io.IOException

tryToFindAvailableSocketPort

public static int tryToFindAvailableSocketPort(int defaultPort)

tryToFindAvailableSocketPort

public static int tryToFindAvailableSocketPort()

findAvailableSocketPorts

public static int[] findAvailableSocketPorts(int capacity)
                                      throws java.io.IOException

Throws:

java.io.IOException

getLocalHostString

public static java.lang.String getLocalHostString()

copyStreamContent

public static int copyStreamContent(ProgressIndicator indicator,
                                    java.io.InputStream inputStream,
                                    java.io.OutputStream outputStream,
                                    int expectedContentLength)
                             throws java.io.IOException,
                                    ProcessCanceledException

Parameters:

indicator - progress indicator

inputStream - source stream

outputStream - destination stream

expectedContentLength - expected content length in bytes, used in progress indicator (negative means unknown length). For gzipped content, it's an expected length of gzipped/compressed content. E.g. for HTTP, it means how many bytes should be sent over the network.

Returns:

the total number of bytes written to the destination stream (may exceed expectedContentLength for gzipped content)

Throws:

java.io.IOException - if IO error occur

ProcessCanceledException - if process was canceled.

isSniEnabled

public static boolean isSniEnabled()
