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)

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 
)

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
keyparameter from BES configuration file
strmif not buffered then use the passed stream
strm_ownedif strm created (not cout or cerr for example) then tells whether strm owned or not and can be deleted
ishttptells whether this text information is html text and therefor requires the html header

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
eThe exception to add to the informational response object
adminThe contact information for the person responsible for this error
