In a K2 process system, any one of the execution nodes in the process (one node can contain multiple events) can contain client events, server-side events, and subprocesses (Ipc,inter process Communication) events, or other events. Typically, we need to include a lot of business logic in the process node, such as who is the performer of the process node. Which prerequisites must be satisfied before the performer initiates the process node task, and so on. A process node is a key element in a pro

At-rules different CSS rules for use in specific situations. Importing importThe @ rule references another style. For example, if you want to add another style to the current style, you can do this: @import url(addonstyles.css); This is much like using link elements to connect CSS to HTML, which essentially has a content style like the following: This is to take care of the old version of the browser, such

When we use makefile, there are things that we often use and use very frequently. For example, we compile the C/C ++ source.ProgramIs the intermediate target file (UNIX is the [. O] File, Windows is the [. OBJ] file ). This chapter describes some "implicit" rules in makefile, which were previously agreed and do not need to be written again. "Implicit rules" is also a convention. Make will follow this "Con

Implicit rules---- When we use makefile, there are things that we often use and use very frequently, such, we compile the C/C ++ source program as the intermediate target file (in UNIX, it is [. o] file, which is [.
