Class::AlzaboWrapper::Cursor - Higher level wrapper around Alzabo cursor objects
my $cursor = Class::AlzaboWrapper::Cursor->new( cursor => $cursor );
This module works with
Class::AlzaboWrapper to make sure that objects returned from cursors are of the appropriate
Class::AlzaboWrapper subclass, not raw
THIS MODULE IS STILL AN ALPHA RELEASE. THE INTERFACE MAY CHANGE IN FUTURE RELEASES.
This module provides the following methods:
This method expects a
cursor parameter, which should be an
Alzabo::Runtime::Cursor object. This is the cursor being wrapped by this class.
It also takes an "args" parameter. This is an optional array reference. If given, then the arguments specified will be passed when calling
new() for the appropriate subclass(es).
The "constructor_method" argument allows you to specify what method to call when fetching the next object via
next(). This defaults to "new".
This method is called to get the next object (or objects) in the cursor. Internally, it calls
new() on the appropriate
Class::AlzaboWrapper subclass for each
Alzabo::Runtime::Row object returned by the wrapped cursor. It can be called in scalar or array context, but in scalar context it will only return the first object when there are more than one, so be careful.
Wrapper for the cursor's
next_as_hash() method, it behaves the same as
next in that each row is returned as an appropriate
Class::AlzaboWrapper subclass object. Returns a hash keyed to the table name(s).
Returns an array containing all the remaining objects in the cursor. If the wrapped cursor just returned single rows, then it returns an array of objects. Otherwise, it returns an array of array references, with each reference containing one set of objects.
