klog

In the process of Android development and debugging, the use of log is very frequent, a good log tool can save you a lot of time, so klog to write an open source project, hoping to help you improve the efficiency of development, this open source library is inspired by logger Features of Klog Run the Demo Use the detailed KLogd Klogdstring Klogdtagstring Kl

subclass of ContextWrapper. In ContextWrapper, obtaining system services is done directly through mBase. @Override public Object getSystemService(String name) { return mBase.getSystemService(name); } However, in ContextThemeWrapper, this method is rewritten to complete function expansion. @Override public Object getSystemService(String name) { if (LAYOUT_INFLATER_SERVICE.equals(name)) { if (mInflater == null) { mInflater = LayoutInflater.from(getBas

, this method is rewritten to complete function expansion. @Override public Object getSystemService(String name) { if (LAYOUT_INFLATER_SERVICE.equals(name)) { if (mInflater == null) { mInflater = LayoutInflater.from(getBaseContext()).cloneInContext(this); } return mInflater; } return getBaseContext().getSystemService(name); } Of course, if there is no function extension, isn't it the decorator mode? In fact, the design patte

heap of k elements. Next, for I = k + 1 to n: If I is smaller than the root element of the smallest heap, ignore it directly. If I is greater than the root element of the smallest heap, replace the root element of the heap and reconstruct the minimum heap. The correctness is as follows:. In the initial state, all elements in the heap are larger than those in the empty element; B. After each minimum heap reconstruction, the elements in the heap are always larger than all the elements replaced by

Problem: Find the maximum number of K before an array.Solution one (direct solution):The array is sorted quickly, and then the number of k large is directly selected. The time complexity of this method is O (Nlog (N)). N is the original array length.This solution contains a lot of redundancy because the entire array is sorted, and we don't actually need to do that.Solution two (k array sort):First, create an empty array of length K. Select the number of K from the original array to sort and plac

Klog_error ("Init", x) #define NOTICE (x ...) Klog_notice ("Init", x) #define INFO (x ...) Klog_info ("Init", X)This is obviously a log statement with a level of klog_info_level. Whether it can be output to/dev/__kmesg__ is related to the value of the current

The starting steps are as follows: Read the configuration file. Typically, the configuration file for/etc/syslog.conf specifies how the daemon handles different types of log messages. These log messages may be added to a file, or written to a specified user's login window, or forwarded to the SYSLO
