As Program Let's go straight to the topic and see how the streaming workflow works. At least we have a general understanding. Load the rule into the streaming Set some variables used in the Rule File Execute the rule and save the execution result in context) Let's take a look at the composition of the streaming

A rule string consists of zero or multiple characters (such as "hello") in double quotation marks and can contain simple escape sequences (such as \ t indicating a tab), hexadecimal escape sequence and Unicode escape sequence. A verbatim string consists of the double quotation marks followed by the @ character, zero or multiple characters, and ending double quotation marks. A simple example is @ "hello ". In a verbatim string, the character between

Received an e-mail, a friend thought I misunderstood Nf-hipac. Such a high-performance algorithm can be what traditional hash,tree such as coercion. Oh, yes. Hipac is a very fierce algorithm. There is less documentation, which adds to its sense of wonder, but it does not mean that it is incomprehensible. Instead. It's very easy to think.The HIPAC algorithm is essentially a priority-based interval matching algorithm. How do you understand it? We define the match field as a continuous interval, an

This article mainly introduces some of the CSS in the usage summary of the rules, is the basic knowledge of CSS primer learning, the need for friends can refer to the following At-rule is a statement that provides the CSS with instructions for performing or how to behave. Each declaration begins with an @, followed by an available keyword, which acts as an identifier that represents what the CSS does. This is a common syntax, although each at-

ObjectiveThere are few tutorials on the Kie DROOLS Workbench (JBoss BRMS) in the world, and there are only a few of them that have been translated using machines (the unintelligible ones) or some tutorials based on the old version of JBoss Guvnor or 5.x, and these tutorials are " Lack of arms and legs ", the beginner does not know what it is doing? Are you capable? Be able to solve any problems in your system.So I wrote a few examples myself, the entire latest English version of the Kie DROOLS 6

There's a lot of JavaScript code in Web Apps right now, and we've been chasing a variety of solutions that make them faster. 1. We use event delegation to make event monitoring more efficient,2. We use function debouncing to limit the number of times a given method is invoked for a period of time, refer to how to prevent high-frequency triggering of event functions (Chinese translation)3. We use the JavaScript loader to load the part of the resources we really need, and so on. There is also a

Now the internet is not a pure land, in order to prevent attacks from the network, many novice friends have installed a firewall software to protect themselves, but how to use a firewall more practical? Below, follow the author piece, to Skynet firewall as an example, through it to support the function of custom rules, to meet the needs of different types of users, to avoid "prevent others also prevent themselves" embarrassment.
