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.)

Member Typedef Documentation

Constructor & Destructor Documentation

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

ACE_Time_Value timeout = 0,
bool  restart = true,
bool  reset_new_handle = false 
) const
inlineprotected
void ACE_MEM_Acceptor::dump ( void  ) const

Dump the state of an object.

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
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 
)
inlineprotected
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

ACE_MEM_Acceptor::ACE_ALLOC_HOOK_DECLARE

Declare the dynamic allocation hooks.

ACE_MEM_SAP::MALLOC_OPTIONS ACE_MEM_Acceptor::malloc_options_
private

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

ACE_TCHAR* ACE_MEM_Acceptor::mmap_prefix_
private

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

ACE_MEM_IO::Signal_Strategy ACE_MEM_Acceptor::preferred_strategy_
private

Preferred signaling strategy.
