NAME

DTS::Assignment - a Perl base class to represent a DTS Dynamic Properties task Assignment object

SYNOPSIS

package DTS::Assignment::SomethingWeird;
use base (DTS::Assignment);

#and goes on defining the child class

DESCRIPTION

DTS::Assignment is a base class that should be inherited by a specialized class that defines one type of Assignment object that is part of a DTS Dynamic Property task.

This class defines some common attributes that a subclass of DTS::Assignment. Some methods must be override too, and are explained in the next sections.

EXPORT

None by default.

METHODS

new

Instantiates a new DTS::Assigment object. Expects as parameter a DynamicPropertiesTaskAssignment object. Unless you want to extend the DTS::Assignment class, you will want to fetch DTS::Assignment objects using the get_properties method from DTS::Task::DynamicProperty class.

get_type

Returns the type as a numeric code for a instantied object of a subclass of DTS::Assignment.

get_type_name

Returns a type as a string converted from the original numeric code using DTS::AssignmentTypes abstract class to make the convertion.

get_source

This method should be override by any subclass of DTS::Assignment. If invoked but not override, it will abort with an error message.

get_destination

Returns a string with the destination property of an assignment object.

get_properties

Returns all properties from an assignment object as a hash reference, having the following keys:

  • type

  • source

  • destination

Since the method get_source must be overrided by subclasses of DTS::Assingment this method will failed unless invoked thru one of those subclasses.

to_string

Returns a string with the type, source and destination of an assignment. Useful for debugging or reporting.
