Method Detail

main

public static void main(java.lang.String[] args)

Main method for testing this class.

Parameters:

args - String[] : the command line options.

getAttributes

public AttrMap getAttributes()
                      throws PresentationException

Return the attributes with which this presentation was created, or at least the best guess.

Specified by:

getAttributes in class Presentation

Returns:

a map of attributes used to render this Presentation. Currently returns an empty map.

Throws:

PresentationException

toString

public java.lang.String toString(int width)

Render this Presentation as a String with the given width limitation.

Specified by:

toString in class Presentation

Parameters:

width - the maximum number of characters allowed for depiction of this presentation.

Returns:

a representation (rendering) of this Presentation.

parse

public Presentable parse()
                  throws PresentationException

PresentationException

getPresentableClass

public java.lang.String getPresentableClass()

Method to get the name of the corresponding Presentable class for this Presentation.

Specified by:

getPresentableClass in class Presentation

Returns:

_PresentableClass.

audit

public java.lang.String audit(java.lang.String label)

Description copied from interface: Auditable

Method to return a detailed string from an object for debugging purposes.
