Pipeline::Store(3) User Contributed Perl Documentation Pipeline::Store(3)NAMEPipeline::Store - defines the interface for Pipeline store classes
SYNOPSIS
use Pipeline::Store; # interface class, does very little
DESCRIPTION
"Pipeline::Store" provides a constructor and a generic get/set
interface for any class implementing a store to sit on a Pipeline.
Pipeline stores are singletons inside the dispatch process. Ie, if you
attempt to construct a pipeline store in between the dispatch method
being called on a pipeline segment and having the method return a value
then you will get the same store as that segments store() method.
METHODS
The Pipeline class inherits from the "Pipeline::Base" class and
therefore also has any additional methods that its superclass may have.
new()
The "new" method constructs a new Pipeline::Store object and calls
the "init" method. If the transaction flat is set then it returns
the current store singleton.
init()
The "init" method is called by new() to do any construction-time
initialization of an object.
start_transaction
Sets the transaction flag, which makes the store object that this
is called on a singleton until end_transaction is called.
end_transaction
Clears the transaction flag, which lets you construct new pipeline
stores.
store( [ store ] )
The "store" method gets or sets the store in a Pipeline::Store
object. Unless "init" is changed the store is set at construction
time to a hash reference.
get()
Does nothing in Pipeline::Store - exists as a placeholder for
subclasses.
set()
Does nothing in Pipeline::Store - exists as a placeholder for
subclasses.
