NAME

DTA::TokWrap::Base - DTA tokenizer wrappers: base class

SYNOPSIS

 use DTA::TokWrap::Base;
 
 ##========================================================================
 ## Constructors etc.
 
 $obj = $CLASS_OR_OBJ->new(%args);        ##-- inheritable constructor
 %defaults = $CLASS_OR_OBJ->defaults();   ##-- set static defaults
 $obj = $obj->init();                     ##-- set dynamic defaults

DESCRIPTION

DTA::TokWrap::Base provides an abstract base class for all object classes in the DTA::TokWrap distribution

Constants

Variable: @ISA: DTA::TokWrap::Base inherits from DTA::TokWrap::Logger.

Constructors etc.

new

 $obj = $CLASS_OR_OBJ->new(%args);

Generic constructor. %args is a hash of subclass-dependent constructor options.

The default implementation calls $CLASS_OR_OBJ->defaults() before the new object is instiated, and and $obj->init() afterwords.

defaults

 %defaults = CLASS_OR_OBJ->defaults();

Subclasses may define a defaults() method to set static (class-dependent) object defaults. The return value %defaults should be an object option hash.

The default implementation just returns an empty hash.

init

 $obj = $obj->init();

Subclasses may define an init() method to compute dynamic (object-dependent) object defaults.

The default implementation does nothing.
