For smooth transition, a BGP spokesman egp2 and BGP-4 can be involved. Therefore, a BGP spokesman may receive IP accessibility information from egp2 or BGP-4. Information generated by egp2 that can be inserted into the BGP-4 after the origin path property is set to 1. Similarly, info

associated with weak references can only survive until the next garbage collection occurs. When the garbage collector is working, the objects that are only referenced are reclaimed regardless of whether the current memory is sufficient. After JDK 1.2, the WeakReference class was provided to implement weak references. Weak references can be used where, when you want to reference an object, but this object has its own life cycle, you do not want to intervene in the life cycle of this object, you

If this phase goes wrong, then all the good experiences in the future are equal to zero, or to a certain extent, create a shadow for the user. The smooth "access" of Internet products is a big topic, which refers to "access" in a broad sense, not just whether it can be opened so easily. At present, the indicators are subdivided into four categories

process directives, rather than setting false expectations. When designing a form layout, consider using the "jump" experience of the TAB key. Use the "TabIndex" HTML property to control the form's jump order. "For many users with disabilities, the design accessibility of a form is particularly important," said Peter Vaulec, Oracle's accessibility director. Availability is at the heart of

garbage collector prepares to reclaim an object, if it finds that it has a virtual reference, it will add the virtual reference to the reference queue associated with it before reclaiming the object's memory. Referencequeue queue = new Referencequeue ();Phantomreference PR = new Phantomreference (object, queue); The program can see if the referenced object is going to be garbage collected by judging whether the reference queue has been added to the virtual reference. If the program discovers th

It's not easy to put thin, tall pictures and wide, short pictures together. If you want to modify a sprite in a picture, you need to modify the entire picture, which will undoubtedly increase the workload. Making CSS difficult to write If the CSS sprite is complex enough, it greatly increases the amount of code and difficulty of CSS
