6.1 albatross.template -- Base classes for implementing tags

The module contains the following classes which are intended to be used in implementing custom tags.

class Tag( ctx, filename, line_num, attribs)
This is the base class upon which all tags are implemented. You are unlikely to ever subclass this directly. The EmptyTag and EnclosingTag classes inherit from this class.

class EmptyTag( ctx, filename, line_num, attribs)
Use this class as a subclass for all tags which do not require a closing tag and therefore do not enclose content. Examples of standard HTML tags which do not enclose content are <BR> and <HR>.

class EnclosingTag( ctx, filename, line_num, attribs)
Use this class as a subclass for all tags which enclose content. Examples of standard HTML tags which enclose content are <BODY> and <TABLE>.

class Text( text)
A simple wrapper around the string passed in the text constructor argument which passes that string to the to_html() method when the object is converted to HTML.

class Content( )
A simple wrapper around a list which calls the to_html() method of all list elements when the object is converted to HTML.
