"Go" (GO) how the Linux kernel accesses peripheral I/O resources-static mapping (MAP_DESC) modeHow the Linux kernel accesses peripheral I/O resourcesAuthor:dongasdate:08-08-02We know that the default peripheral I/O resources are not in the Linux kernel space (such as SRAM or hardware interface registers, etc.), and if you need access to the peripheral I/O resources, you must first map its address to kernel space before it can be accessed in kernel spa

ORM. The full name is (objectrelational Mapping), which is the objects relational mapping. The idea of ORM is to map the data of tables in a relational database into objects. Presented in the form of objects. This enables developers to translate the operations of the database into operations on those objects. Hibernate is the realization of this idea, to facilitate the developers to the object-oriented thin

Mapping overviewNHibernate as a typical ORM tool, we used to define domain first and then map the database relationship to domain, and the nhibernate mapping was in the form of an XML file. This article from the overall understanding of the next nhibernate mapping process and our way of writing.Mapping processing processWhen we confrontation NHibernate, what did

Shadow mapping has become standard for the current 3D games. The traditional sm+pcf can realize the hard Shadow in the sunlight environment well, but if the soft Shadow produced by dim light is to be realized, either the effect is too blunt (sample number is less) or inefficient (sample number of times). As a result, more and more games are starting to use soft shadow algorithms that take full advantage of hardware features.Here mainly summarizes vari

As explained by data in, data out, each document in index has a type. Each type has its own mapping or schema definition. Define filed in type mapping, define the data type in each filed, define how ES handles this filed,mapping is also used to configure the metadata associated with that type.We will discuss mapping

Unidirectional one-to-many association mappingsThe mapped relational model:Map file:A one-to-many correlation mapping and a multiple-to-one correlation mapping principle are consistent, with the addition of a foreign key to one end of a multi-pointThe difference between them is that they maintain different relationships:* Many-to-one maintenance relationship is: a multi-point relationship, with this relatio

// Please specify the source: Http://blog.csdn.net/BonChoix, thank you ~) Tangent spaces (Tangent space) Switching space, same as local space, world space, is one of the many coordinate systems in 3D graphics. One of the most important uses for switching between spaces is the normal mapping (normal Mapping). Details about the normal mappings are detailed in the next article. However, it is important to und

The idea of its realization is to map the data of tables in the relational database into objects, so that the developers can transform the operation of the database into the operation of the objects. So it is design

3.3. Mapping methods with several source parameters (mapping method with multiple source parameters)Mapstruct also supports mapping methods with multiple source parameters. This is useful, for example: in order to merge multiple entities into one data transfer object. An example is shown below:Example 10. Mapping metho

ObjectiveFor Java developers, annotations should not be an unfamiliar concept, as early as the javase phase, such as the @override tag overriding the parent class method or implementing an interface method, @Test tag unit test method, so we can simply interpret it as a tag with special meaning ... In the development process, we can also use annotations to replace the configuration file implementation of related features, such as Java Web Development, 3.0 version, the use of @webservlet, @WebList

Mapping typeThe mapping settings typically occur in:1. When adding a new index, add the mapping type to set the fields mappingPUT Twitter {"Mappings": { "Tweet": { "Properties": { "message": { "type":"string" } } } }}2. Add a new mapping type for index, set the

Previous blog post "SSH Advanced path" hibernate mapping-one-to-one unidirectional correlation mapping (v), we introduced one-to-two unidirectional association mappings, one-way refers to the only people (person) on this side to load the identity card (Idcard), but in turn, can not be added from the identity card side information. :The key reason is that the object model has directionality:unidirectional:

ORM Entity Relationship Mapping, the relationship between data tables and tables in a database, is manifested by the relationship between entity bean and entity bean, and the operation of database by manipulating entity Bean is realized. ORM (Object-relation-map), where Object represents the entity bean,relation represents the data table, and map represents the mapping of the entity bean to the data tabl
