Instead of implementing my own I was wondering if anyone knows of a histogram or bag datastructure implementation in Objective-C that I can use. Essentially a histogram is a hashmap of lists where the lists contain values that relate to their hash entry. A good example is a histogram of supermarket items where you place each group of it...
we have a collection of comparable held in a bag and have to find the kth largest element. I copied to a hashSet to remove duplicates then converted the hash set to an array to be sorted and consequently the kth element accessed. its compiling but fails the testing, and I can't figure out whats wrong. any ideas? public E kth(int K){ ...
I find myself very intrigued by the existence of a ConcurrentBag<T> class in the upcoming .NET 4.0 framework: Bags are useful for storing objects when ordering doesn't matter, and unlike sets, bags support duplicates. My question is: how might this idea be implemented? Most collections I'm familiar with essentially amount to (under...
Hello, I have the following class-mapping that contains multiple collections mapped as : Code: <class entity-name="tab_a" table="tab_a" lazy="true" schema="dbo" dynamic-update="false" dynamic-insert="false" select-before-update="false"> <id name="tabid" type="string" column="`TABID`"> <generator class="nativ...
I'm looking for a .Net implementation of a multiset. Can anyone recommend a good one? (A multiset, or bag, is a set that can have duplicate values, and on which you can do set operations: intersection, difference, etc. A shopping cart for instance could be thought of as a multiset because you can have multiple occurrences of the same pr...
I have a component mapped using Hibernate. If all fields in the component in the database are null, the component itself is set to null by hibernate. This is the expected behavior and also what I need. The problem I have, is that when I add a bag to that component, the bag is initialized to an empty list. This means the component has a ...
Im really hoping someone can help with this, have been trying various combinations for a day and a half now.... Basically I have a some hierarchical data stored in a single table, the usual parentID maps to a row id scenario. I have modelled a property within the domain object that returns a list of ancestors for a given item. It all s...
Hi all, I am experiencing some strange problems with NHibernate and the usage of proxy items within a bag. My mapping looks something similar to: <?xml version="1.0" encoding="utf-8" ?> <bag name="Markets" table="ITPUserWatchlistMarkets" cascade="none" lazy="false"> <key column="UserWatchlistId" /> <many-to-many class="Swan.Dom...

Does anyone know if the property bag settings for a sharepoint 2007 site is included in content deployment? my google foo has failed me today for a solidified answer. ...
I have a list of pairs of objects. Objects can appear in the pair in either order. What is the most efficient algorithm (and implementation?) to find all bags (ie sets with duplicates permitted) of pairs between the same objects. For my purpose the object references can be assumed to be pointers, or names or some similar convenient, shor...
