=head1 DESCRIPTION |
79
|
|
|
|
|
|
|
|
80
|
|
|
|
|
|
|
C is designed as a part of the C system. The |
81
|
|
|
|
|
|
|
C class is designed to be subclassed as a part of the Pipeline |
82
|
|
|
|
|
|
|
system. The primary method that needs to be overloaded is the C method, |
83
|
|
|
|
|
|
|
which the Pipeline class uses to enter each individual segment that it contains. |
84

=head1 METHODS |
86
|
|
|
|
|
|
|
|
87
|
|
|
|
|
|
|
The C class inherits from C and therefore |
88
|
|
|
|
|
|
|
also has any additional methods that its superclass may have. |

=item init() |
93
|
|
|
|
|
|
|
|
94
|
|
|
|
|
|
|
The C method is called at construction time. Any arguments passed to the |
95
|
|
|
|
|
|
|
C method are passed to it. |

98
|
|
|
|
|
|
|
|
99
|
|
|
|
|
|
|
The C method causes the segment to perform its action. |

101

102
|
|
|
|
|
|
|
|
103
|
|
|
|
|
|
|
The C gets and sets the method that gets called on dispatch, by |
104
|
|
|
|
|
|
|
default this is the C method. |
105
|
|

=item cleanup_dispatch() |
107
|
|
|
|
|
|
|
|
108
|
|
|
|
|
|
|
The C method does post-processing on the segment to ensure |
109
|
|
|
|
|
|
|
no nasty circular references are lying around, as well as disconnecting |
110
|
|
|
|
|
|
|
various objects that are only useful during a dispatch. |
111
|
|
|
|
|
|
|
|
112
|
|
|
|
|
|
|
=item store() |
113
|
|
|
|
|
|
|
|
114
|
|
|
|
|
|
|
The C method gets the current store. |
115
|
|
|
|
|
|
|
|
116
|
|
|
|
|
|
|
=item parent() |
117
|
|
|
|
|
|
|
|
118
|
|
|
|
|
|
|
The C method returns the pipeline that the segment is current operating from. |
119
|
|
|
|
|
|
|
It is set at dispatch time by the calling pipeline. |
