Member Function Documentation

Console * Console::getConsole (    )  [static]

Returns the singleton Console instance. Precondition: none. Postcondition: Construct a singleton instance. Replaced cout. Returns: Signleton Console instance pointer.

Console & Console::operator<< (  const string &    line )

Print a string to the console. Prints an logs a single line. Precondition: none. Postcondition: The line is appended to 'text'. Parameters: line  The line to print. Returns: reference to this.

void Console::refresh (    )  [virtual]

Repaints the region. This method is called whenever the screen is repainted. The repaint method uses OpenGL calls to render the region. Currently it is assumed that regions are refreshed automatically so that no refresh notification has to be done when the region changes state i.e. no refresh has to be forced by the region. Region rendering is done back to front. Precondition: An OpenGL context has been created and activated to render in. Postcondition: The region is redrawn. Reimplemented from Region.

void Console::resize (  unsigned short    w, unsigned short    h )  [virtual]

Resizes the region. Virtual method to change the size of the Region. Parameters: w  New width. h  New height. Postcondition: The region has been resized to (w, h). Reimplemented from Region.
