Overview
As we all know, in ASP. in the. NET application, we can use the verification control to verify data input. Unfortunately, no verification control is provided in Silverlight, however, Silverlight provides some basic data verification support for bidirectional data binding. We can define verification rules in the set configurator and throw an exception for invalid data, finally, data verification is implemented by capturing verification error e

The first level uses malloc, free, and the second level uses different strategies depending on the situation.Such a mechanism takes space from the heap and can resolve memory fragmentation issues.1.

Creation (workspace build).The project creation lifecycle mapping can be configured in the project's Pom.xml file, or provided by the Eclipse plug-in, or by default with the Maven plugin provided by M2E. The Life cycle mapping source We call the life cycle mapping Meta data source (lifecycle mapping metadata sources). If the corresponding life cycle mappings are not found in these life cycle mapping metadata sources, M2E creates an error token similar to the following (Error marker):For plug-in

STL provides six major components that can be combined
1, container (containers): a variety of data structures, such as vertor,list,deque,set,map. From the perspective of implementation, the STL container is a class template
2, Algorithm (algorithms): various algorithms such as Sort,search,copy,earse. STL algorithm is a function template.
3, iterator (iterators): act as a glue between the container and the algorithm, is called "Generic pointer." All STL containers have their own dedicated ite
