Detailed Description

HTTP_Client is intended to provide application API to classes that wish to do network i/o at a very high level of abstraction.

This class provides the ability to retrieve data from the network, of specified length and offset, and potentially use any protocol "under the hood" to do so. It currently uses HTTP. See HTTP_Handler also.

Member Function Documentation

int TAO_HTTP_Client::close

(

void

)

Frees memory allocated for filename.

Definition at line 49 of file HTTP_Client.cpp.

{
  if (this->filename_)
    {
      ACE_OS::free ((void *) this->filename_);
      this->filename_ = 0;
    }

}

int TAO_HTTP_Client::open	(	const ACE_TCHAR *	filename,
		const ACE_TCHAR *	hostname = ACE_DEFAULT_SERVER_HOST,
		u_short	port = 80
	)

Initializes the class with the given filename, hostname and port. it should be called with the filename, before any read/write calls

Definition at line 22 of file HTTP_Client.cpp.

{
  this->filename_ = ACE_OS::strdup (filename);
  this->inet_addr_.set (port, hostname);
  return 0;
}

int TAO_HTTP_Client::read

(

ACE_Message_Block *

mb

)

Starts a connection, and reads a file from the server into Message_Block mb

Definition at line 32 of file HTTP_Client.cpp.

{
  // Create a HTTP_Client Reader
  TAO_HTTP_Reader HTTP_reader (mb, this->filename_);
  TAO_HTTP_Handler *brp = &HTTP_reader;

  // Connect to the server
  if (connector_.connect (brp, this->inet_addr_) == -1)

      ACE_ERROR_RETURN ((LM_ERROR, "TAO (%P|%t) - HTTP_Client::read, Connector error\n"), -1);
    }

  return HTTP_reader.byte_count ();
