hierarchies, but it has nothing to do with the core functionality of the objects it spreads to. This is true for many other similar functions, such as transaction management, permission control, and so on. This leads to a large amount of duplication of code, which is not conducive to the reuse of individual modules. PS: In fact, I have a certain understanding of AOP, but can not be particularly clear to express it .....Take a look at an overview of t
the reason and thought of character stream appearing ? Because the byte stream operation Chinese is not particularly convenient, so Java provides a character stream. Character stream = byte stream + encoding table.

Overview of the two basic specificationsDTS (device tree syntax, another way of saying device tree source) is a plant-based file that is used in text format for readability and modification. The DTC (device tree compiler) is a small tool that is responsible for converting DTS into a DTB (device tree blob). DTB is a binary form of DTS for use by machines. In use, we first modify the DTS file according to the hardware, and then at compile time through t
; It is found that the waiting threads are fetched to the lock in the order in which they were blocked. This is because Aqs is based on a CLH lock queue variant called to implement the thread blocking queue, and our next article will simply understand the next CLH lock queue.Follow-up articles are planned as follows:

There is types of frame structure in the LTE standard, type 1 and type 2. Type 1 uses Frequency Division duplexing (Uplink and downlink separated by Frequency), and TDD uses time division Duplexin G (Uplink and downlink separated in time). This overview covers both LTE FDD Type 1 signals and LTE TDD type 2 signals described in the standard documents listed in The About Opts BHD and bhe:lte modulation analysis topic.
