Detailed Description

Defines the format and interface for the acceptor side of the local mmap stream.

This class should be modified to prevent user passing a non-localhost endpoint as the acceptor listen point because it doesn't make any sense at all to make the listening endpoint visible (or connectable) anywhere outside of this machine. However, the type of endpoint is left as <ACE_Addr> so we can later changed to use UNIX-domain sockets with mmap stream if so desired. (Currently, using UNIX-domain sockets, i.e., ACE_LSOCK_*, with this class will not work.)

ACE_MEM_Acceptor::ACE_MEM_Acceptor ( void  )

Default constructor.

ACE_MEM_Acceptor::~ACE_MEM_Acceptor ( void  )

Destructor.

ACE_MEM_Acceptor::ACE_MEM_Acceptor ( const ACE_MEM_Addr remote_sap,
int  reuse_addr = 0,
int  backlog = ACE_DEFAULT_BACKLOG,
int  protocol = 0 
)

Initiate a passive mode socket.


Member Function Documentation

int ACE_MEM_Acceptor::accept ( ACE_MEM_Stream new_ipc_sap,
ACE_MEM_Addr remote_addr = 0,
ACE_Time_Value timeout = 0,
bool  restart = true,
bool  reset_new_handle = false 
)

Accept a new data transfer connection.

int ACE_MEM_Acceptor::accept ( ACE_SOCK_Stream new_stream,
ACE_Addr remote_addr = 0,
ACE_Time_Value timeout = 0,
bool  restart = true,
bool  reset_new_handle = false 
) const [inline, protected]

Accept a new ACE_SOCK_Stream connection. A timeout of 0 means block forever, a timeout of {0, 0} means poll. restart == true means "restart if interrupted," i.e., if errno == EINTR. Note that new_stream inherits the "blocking mode" of this ACE_SOCK_Acceptor, i.e., if this acceptor factory is in non-blocking mode, the new_stream will be in non-blocking mode and vice versa.

Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::accept ( ACE_SOCK_Stream new_stream,
ACE_Accept_QoS_Params  qos_params,
ACE_Addr remote_addr = 0,
ACE_Time_Value timeout = 0,
bool  restart = true,
bool  reset_new_handle = false 
) const [inline, protected]

Accept a new ACE_SOCK_Stream connection using the QoS information in qos_params. A timeout of 0 means block forever, a timeout of {0, 0} means poll. restart == true means "restart if interrupted," i.e., if errno == EINTR. Note that new_stream inherits the "blocking mode" of this ACE_SOCK_Acceptor, i.e., if this acceptor factory is in non-blocking mode, the new_stream will be in non-blocking mode and vice versa.

Reimplemented from ACE_SOCK_Acceptor.

void ACE_MEM_Acceptor::dump ( void  ) const

Dump the state of an object.

Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::get_local_addr ( ACE_MEM_Addr sap) const [inline]

Return the local endpoint address in the referenced <ACE_Addr>. Returns 0 if successful, else -1.

void ACE_MEM_Acceptor::init_buffer_size ( ACE_OFF_T  bytes) [inline]

Change the initial MMAP buffer size (in bytes) of the MEM_Stream this MEM_Acceptor creates.

const ACE_TCHAR * ACE_MEM_Acceptor::mmap_prefix ( void  ) const [inline]

Accessor/mutator of mmap filename prefix. By default, the <mmap_prefix_> is not set and the mmap filename is ${(TMP|TEMP)}//ACE_MEM_Acceptor_(port-number)_(&stream), otherwise, it is <mmap_prefix_>_(port-number)_(&stream), <mmap_prefix_> should include _absolute_ path so the connector within the same host can located the mmap file. Example: /tmp/mmapfile.

void ACE_MEM_Acceptor::mmap_prefix ( const ACE_TCHAR prefix) [inline]
int ACE_MEM_Acceptor::open ( const ACE_MEM_Addr local_sap,
int  reuse_addr = 0,
int  backlog = ACE_DEFAULT_BACKLOG,
int  protocol = 0 
)

Initialize a passive-mode BSD-style acceptor socket (no QoS). local_sap is the address that we're going to listen for connections on. If reuse_addr is 1 then we'll use the SO_REUSEADDR to reuse this address. Returns 0 on success and -1 on failure.

int ACE_MEM_Acceptor::open ( const ACE_Addr local_sap,
int  reuse_addr = 0,
int  protocol_family = PF_INET,
int  backlog = ACE_DEFAULT_BACKLOG,
int  protocol = 0 
) [protected]

Initialize a passive-mode BSD-style acceptor socket (no QoS). local_sap is the address that we're going to listen for connections on. If reuse_addr is 1 then we'll use the SO_REUSEADDR to reuse this address. Returns 0 on success and -1 on failure.

Reimplemented from ACE_SOCK_Acceptor.

int ACE_MEM_Acceptor::open ( const ACE_Addr local_sap,
ACE_Protocol_Info protocolinfo,
ACE_SOCK_GROUP  g,
u_long  flags,
int  reuse_addr,
int  protocol_family,
int  backlog = ACE_DEFAULT_BACKLOG,
int  protocol = 0 
) [inline, protected]

Initialize a passive-mode QoS-enabled acceptor socket. Returns 0 on success and -1 on failure.

Reimplemented from ACE_SOCK_Acceptor.

ACE_MEM_IO::Signal_Strategy ACE_MEM_Acceptor::preferred_strategy ( void  ) const [inline]

Get the preferred signaling strategy.

void ACE_MEM_Acceptor::preferred_strategy ( ACE_MEM_IO::Signal_Strategy  strategy) [inline]

Set the preferred signaling strategy.

int ACE_MEM_Acceptor::shared_accept_finish ( ACE_MEM_Stream  new_stream,
int  in_blocking_mode,
bool  reset_new_handle 
) const

Perform operations that must occur after <ACE_OS::accept> is called.


Member Data Documentation

Declare the dynamic allocation hooks.

Reimplemented from ACE_SOCK_Acceptor.

A cached MALLOC_OPTIONS. MEM_Accaptor use it to create the shared mamory malloc upon every incoming connection.

The filename prefix of the created mmap files. It should contains the absolute path name of the file.

Preferred signaling strategy.
