Poor memory: 48-java Interceptor-Comparison of built-in dynamic proxies and CGLIB in JDK (3), 48-javacglib The dynamic proxy class in Java must implement an interface, and it is said that reflection is not very efficient. Then CGLIB was born.Using CGLib to implement dynamic proxy is not restricted by the interface that the proxy class must implement. Besides, CGLib uses the ASM bytecode generation framewor

During development, sometimes the icon is slightly larger. For example, when it is 48 × 48, the text will be superimposed with the icon. The solution is as follows: Copy codeThe Code is as follows: TabWidget tw = tabHost. getTabWidget (); For (int I = 0; I { TextView TV = (TextView) tw. getChildAt (I). findViewById (android. R. id. title ); ImageView iv = (ImageView) tw. getChildAt (I). findViewById (an

static object initialization, and it is difficult to ensure that each such object is initialized in multiple compilation units, especially if the program becomes more complex by adding more such non-local static objects.A singleton mode, which transfers each non-local static object to a function, declares it to be static, and second, lets the function return a reference to the object. This allows the user to specify the object with a function called, which is to replace the non-local static obj

-related template (that is, expression templates), it is possible to eliminate those temporary objects and merge loops. Therefore, TMP uses less memory, and the execution speed is improved. Custom design pattern implementations can be generated. Using the tmp-based technology of policy-based design, it is possible to generate some templates to express independent design items (so-called policies), and then can combine them arbitrarily, resulting in the pattern implementation of the prod
