Package org.craftercms.commons.mongo

Class AbstractJongoRepository<T>

java.lang.Object
org.craftercms.commons.mongo.AbstractJongoRepository<T>
All Implemented Interfaces:
CrudRepository<T>
public abstract class AbstractJongoRepository<T> extends Object implements CrudRepository<T>
Simple interface to interact with Jongo/MongoDB.
Changes MongoException in to MongoRepositoryException (which is a checked exception).As well if Command result is not ok (CommandResult#isOk) return false a exception will be thrown the message for that exception will be CommandResult#getErrorMessage.
Some of the find and insert methods use a template queryName. this means that the string can contain placeholders ('#') this will allow the user to have predefine json strings that will be substitute with the given params.Params are not Name therefor if the same value is needed multiple times for now it has to be send multiple times.Order of the params should match the same in the json string.

This class is mark as abstract to force inheritance , so we can get in runtime the class of the generic parameter with this we can simplify the mapping.
