Yote::ObjProvider - Serves Yote objects. Configured to a persistance engine.
This module is essentially a private module and its methods will not be called directly by programs. This module is the front end for assigning IDs to objects, fetching objects, keeping track of objects that need saving (are dirty) and saving all dirty objects. It is the only module to directly interact with the datastore layer.
returns the number of items in the given container
Requests the data store used commit the transaction.
Marks the object as dirty
Requests the data store used disconnect.
Returns a string of the argument encrypted.
Removes any object with the given ID from any cache
Returns the array ref, hash ref or yote object specified by the numeric id or hash path.
Returns the id of the first object in the system, the YoteRoot.
Clears out DIRTY and WEAK_REFS caches.
Returns the id assigned to the array ref, hash ref or yote object. This method assigns that id if none had been assigned to it.
Removes the key from the hash given by the id
Inserts the item into the list with an optional index. If not given, this inserts to the end of the list.
This is just used when multiple processes will be activatig the same data share.
This method returns a list of the public API methods attached to the given package name. This excludes the automatic getters and setters that are part of yote objects.
Returns a paginated list or hash that is attached to the object specified by obj_id. Arguments are
* name - name of data structure attached to this object. * search_fields - a list of fields to search for in collections of yote objects * search_terms - a list of terms to search for * sort_fields - a list of fields to sort by for collections of yote objects * reversed_orders - a list of true or false values corresponding to the sort_fields list. A true value means that field is sorted in reverse * limit - maximum number of entries to return * skip - skip this many entries before returning the list * return_hash - return the result as a hashtable rather than as a list * reverse - return the result in reverse order
Returns a paginated hash reference
Returns a paginated list reference
Returns a deep clone of the object. This will clone any object that is part of the yote system except for the yote root or any app (a Yote::AppRoot object)
Recycles all objects in the range given if they cannot trace back a path to root.
This is a helper method that clears out a changed hash. The hash stores objects that become dirty until reset changed is called again.
Returns a paginated search list
Requests that the underlying data store start a transaction.
This saves the hash ref, array ref or yote object argument in the data store.
Stows all objects that are marked as dirty. This is called automatically by the application server and need not be explicitly called.
Returns the internal yote storage for the value, be it a string/number value, or yote reference.
Returns the external value given the internal identifier. The external value can be a string/number value or a yote reference.
