mapping

问题 Unfortunately I'm still struggling a little with the new Kinect SDK 1.7. This problem is actually in the same context as "finding events via reflection c#": the Click event (however, it is not necessary for understanding this problem). My Problem is simple: if I have my right hand controlling the cursor (the "new" Kinect HandPointer) and it's in the upper left corner of the screen I want it to return the Coordinates (0,0). If the cursor is in the lower right corner the coordinates should be

问题 Hi I'm having a hard time mapping an abstract nested property's fields. Here I have the test case that explains it better: package com.mycompany.asd; import org.junit.Assert; import org.junit.Before; import org.junit.Test; import ma.glasnost.orika.MapperFactory; import ma.glasnost.orika.MappingException; import ma.glasnost.orika.impl.DefaultMapperFactory; /** * Tests the mapping of abstract nested property's fields */ public class OrikaTest { private MapperFactory mapperFactory; @Before

问题 I have an existing data scheme I'm reluctant to change. There are two entities/tables: parent and child , with child having the foreign key column parent_id . It's a 1(parent)-to-n(children) relationship. Is it possible within Spring Data JDBC to have Child class reference Parent and not Parent have a Set<Child> property? Maybe both? (I know it is possible with hibernate, but I'd like to stay with JDBC). I.e. I want something like this: @Data public class Parent { @Id private Long id; } @Data

问题 let's begin with the simple form. Imagine you have a simple dataset like this one: you want to retrieve the cumulative amounts for each asset. First I would filter (arrange) the array by the asset value var pairs = ["eur", "usd", "pop", "dot", "cad", "sol"]; for(i=0; i<pairs.length; i++){ var filtArray1 = dataArray.filter(function filt(el){return el.asset === pairs[i];}); filtArrays.push(filtArray1); and then perform any sort of operations, like summing up for istance: var values = Object

问题 I have been trying to look for solutions to the problem that I am currently having with mapping my DDD model using Fluent NHibernate. If someone can just put me in the right direction that would be appreciated. Basically I have this class that I would like to map: public class A : EntityObject { //assuming some other attributes have been mapped properly public virtual Location MyLocation { get; private set; } } public class Location : EntityObject { public virtual string Name { get; private

问题 there exists a nice database called LiteDB. What I find inconvenient is an absence of attributes for specifying the relation type (value/reference) between entities, though LiteDB provides fluent interface for hardcoding it (details: https://github.com/mbdavid/LiteDB/wiki/DbRef). I am lazy guy and don't want always update this hardcoded relations to follow the changes in my data model. So I decided to realize the runtime discovery of the data model entities with the properties attributed by

问题 I have an existing data scheme I'm reluctant to change. There are two entities/tables: parent and child , with parent having the foreign key column child_id . It's a 1-to-1 relationship. The problem is: the magic behind the scenes expects the child table to have the foreign key column (the exception mentions a ...JOIN ON child.parent = parent.id ). Is it possible to inverse this to match the existing scheme? (I know it is with hibernate, but I'd like to stay with JDBC). Relevant code:

问题 Without subclassing dict, what would a class need to be considered a mapping so that it can be passed to a method with ** from abc import ABCMeta class uobj: __metaclass__ = ABCMeta uobj.register(dict) def f(**k): return k o = uobj() f(**o) # outputs: f() argument after ** must be a mapping, not uobj At least to the point where it throws errors of missing functionality of mapping, so I can begin implementing. I reviewed emulating container types but simply defining magic methods has no effect
