public class DbForumCategory
extends java.lang.Object
implements ForumCategory, Cacheable, com.tangosol.io.ExternalizableLite

Database implementation of the ForumCategory interface. The SQL tree structure we use is Joe Celko's. For more information, see: http://searchdatabase.techtarget.com/tip/1,289483,sid13_gci537290,00.html.

The lft and rgt column values are responsible for defining the tree. An example tree with the lft and rgt column values (respectively) is as follows:

 

            (1,12)
          /       \
      (2,3)      (4,11)
               /   |   \
             /     |    \
          (5,6)  (7,8) (9,10)
 

As you can see from the tree, the lft and rgt values of a child are always between the values of its parent. We can use this property to load the entire tree into memory using a single select. The simple way to determine the lft and rgt values of an arbitrary tree structure is to label lft then rgt by traversing the tree in depth-first order.

getThreadCount

public int getThreadCount()

Description copied from interface: ContentRetrieval

Returns the number of threads in the community. Note: this method ignores permissions because it's not possible to do a database query for the count that obeys permissions counts.

Returns:

the number of threads in the community.

getThreadCount

public int getThreadCount(ResultFilter resultFilter)

Description copied from interface: ContentRetrieval

Returns the number of threads in the community based on the specified ResultFilter.

Returns:

the number of messages in the community.

getMessageCount

public int getMessageCount(ResultFilter resultFilter)

Description copied from interface: ContentRetrieval
