base class interface6, some classes are to do the base class but not to support polymorphism.7. Classes with polymorphic properties or classes with virtual functions should have virtual destructors, not for polymorphic categories with virtual destructors.Article 8: Don't let an exception escape destructor "Review exception"1, do not let the imaginary function throws an exception, destructors to catch any exceptions, swallow or end the program.2. If t

If you call A[i][j]: Operation on one line: Test1 (A[i]); Test1 parameters: int *pa or int pa[]

About polymorphic1. In the Java programming language, the object variable is polymorphic.2. A reference to a superclass cannot be assigned to a subclass variable.The 3.private method, the static method, the final method, or the constructor, the compiler will be able to know exactly which method should be called, and we will call this called static binding.4. Dynamic binding has a very important feature: there is no need to modify the existing code, you can expand the urban and rural surprises.

Workaround: The access address is: http://127.0.0.1:8080/taxGIS/index.jsp; not http://localhost:8080/taxGIS/index.jsp2, Jquery-ui, and jquery Easyui conflict issues. Both are based on jquery, some methods and property names are the same, resulting in a conflict, looking at the introduction of its JS sequence, after the introduc

capture dependencies between operations, but this is not sufficient to resolve situations where multiple replicas are written in parallel. Instead, we need to use the version number of each replica and each key. Each copy increments its own version number when processing writes, and tracks the version number seen from the other replicas. This information indicates which values to overwrite and which values are saved as a sibling version. A collection of version numbers for all replicas is calle

Date Functions 4. mathematical functions Aggregate Function: A value is generated after a group of values are calculated. Common functions include: Function Name Function meaning Count () Count non-empty rows Max (), min () Ma

to the logical address space of the kernel.If you do not need a physically contiguous page, you can use Vmalloc () only if you need a contiguous page on a logical address, but you will incur some performance penalty.If you want to create and revoke many of the same types of data structures, you can establish a slab cache. The slab allocator maintains an object cache (idle list) for each CPU, which can greatly improve the performance of object allocation and recycling. The slab layer does not al

You can use the annotation/*optional*/in the function definition to emphasize that the formal parameter is optional .16, identifier arguments is a reference to an argument object, an argument object is a class array object , not a real array, it is an object that happens to have a numeric indexed property.17.
