Constructor Detail

WasiServerSocket

public WasiServerSocket()
                 throws IOException

Throws:

IOException

Method Detail

bind

public void bind(InetSocketAddress addr)
          throws IOException

Throws:

IOException

listen

public void listen(int backlog)
            throws IOException

Throws:

IOException

accept

@Nullable
public WasiSocket accept()
                  throws IOException

Throws:

IOException

getLocalSocketAddress

@Nullable
public SocketAddress getLocalSocketAddress()

close

public void close()
           throws IOException

Description copied from interface: Closeable

Closes this stream and releases any system resources associated with it. If the stream is already closed then invoking this method has no effect.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Throws:

IOException - if an I/O error occurs

canAccept

public boolean canAccept()
                  throws IOException

Throws:

IOException

getType

public FileType getType()

Description copied from interface: WasiIO

Gets the WasiIO file descriptor type.

Specified by:

getType in interface WasiIO

Returns:

the WasiIO file descriptor type.

setNonBlocking

public void setNonBlocking(boolean nonBlocking)
                    throws IOException

Description copied from interface: WasiSocketOpt

Enable/disable the non blocking state on this WasiIO

Specified by:

setNonBlocking in interface WasiSocketOpt

Parameters:

nonBlocking - whether to enable or disable the non-blocking socket option

Throws:

IOException - if an I/O error occurs.

setBroadcast

public void setBroadcast(boolean on)
                  throws IOException

Description copied from interface: WasiSocketOpt

Enable/disable the SO_BROADCAST socket option. Only meaningful for datagram sockets; stream sockets should ignore this call.

Specified by:

setBroadcast in interface WasiSocketOpt

Parameters:

on - whether to enable or disable broadcast

Throws:

IOException - if an I/O error occurs.

getBroadcast

public boolean getBroadcast()
                     throws IOException

Description copied from interface: WasiSocketOpt

Get the SO_BROADCAST socket option. Only meaningful for datagram sockets; stream and server sockets always return false.

Specified by:

getBroadcast in interface WasiSocketOpt

Returns:

whether broadcast is enabled

Throws:

IOException - if an I/O error occurs.

setReuseAddress

public void setReuseAddress(boolean on)
                     throws IOException

Description copied from interface: WasiSocketOpt

Enable/disable the reuse address socket option.

Specified by:

setReuseAddress in interface WasiSocketOpt

Parameters:

on - whether to enable or disable the reuse address socket option

Throws:

IOException - if an I/O error occurs.

setReceiveBufferSize

public void setReceiveBufferSize(int size)
                          throws IOException

Description copied from interface: WasiSocketOpt

Set the receive buffer size (SO_RCVBUF).

Specified by:

setReceiveBufferSize in interface WasiSocketOpt

Parameters:

size - the buffer size in bytes

Throws:

IOException - if an I/O error occurs.

getReceiveBufferSize

public int getReceiveBufferSize()
                         throws IOException

Description copied from interface: WasiSocketOpt

Get the receive buffer size (SO_RCVBUF).

Specified by:

getReceiveBufferSize in interface WasiSocketOpt

Returns:

the buffer size in bytes

Throws:

IOException - if an I/O error occurs.

setSendBufferSize

public void setSendBufferSize(int size)
                       throws IOException

Description copied from interface: WasiSocketOpt

Set the send buffer size (SO_SNDBUF).

Specified by:

setSendBufferSize in interface WasiSocketOpt

Parameters:

size - the buffer size in bytes

Throws:

IOException - if an I/O error occurs.

getSendBufferSize

public int getSendBufferSize()
                      throws IOException

Description copied from interface: WasiSocketOpt

Get the send buffer size (SO_SNDBUF).

Specified by:

getSendBufferSize in interface WasiSocketOpt

Returns:

the buffer size in bytes

Throws:

IOException - if an I/O error occurs.
