Detailed Description

brief represents simple text information in a response object, such as version and help inforamtion.

Uses the default add_data and print methods, where the print method, if the response is going to a browser, sets the mime type to text.

Constructor & Destructor Documentation

BESTextInfo::BESTextInfo ( bool  ishttp = false  ) 

constructs a basic text information response object.

Text informational objects can also be sent as html with an html header. We need to know this if the informationl is not buffered. If it isn't buffered then we need to send that text header.

BESTextInfo::BESTextInfo ( const string &  key,
ostream *  strm,
bool  strm_owned,
bool  ishttp = false 
)

constructs a basic text information response object.

Uses the default specified key in the bes configuration file to determine whether the information should be buffered or not.

Text informational objects can also be sent as html with an html header. We need to know this if the informationl is not buffered. If it isn't buffered then we need to send that text header.

Parameters:
key parameter from BES configuration file
strm if not buffered then use the passed stream
strm_owned if strm created (not cout or cerr for example) then tells whether strm owned or not and can be deleted
ishttp tells whether this text information is html text and therefor requires the html header

add a line break to the information

Parameters:
num_breaks the number of line breaks to add to the information

Implements BESInfo.

void BESTextInfo::add_data ( const string &  s  )  [virtual]

add string data to the informational response

Parameters:
s string data to add the informational response

void BESTextInfo::add_data_from_file ( const string &  key,
const string &  name 
) [virtual]

add data from a file to the informational object

This method simply adds a .TXT to the end of the key and passes the request on up to the BESInfo parent class.

Parameters:
key Key from the initialization file specifying the file to be
name A description of what is the information being loaded

void BESInfo::add_exception ( BESError e,
const string &  admin 
) [virtual, inherited]

add exception information to this informational object

Exception information is added differently to different informational objects, such as html, xml, plain text. But, using the other methods of this class we can take care of exceptions here.

Parameters:
e The exception to add to the informational response object
admin The contact information for the person responsible for this error
