This paper, with the example of bolt distribution and assembly, illustrates the application and principle of MES in advanced manufacturing of WMS and manufacturing Execution System of logistics management system.We know that bolts are a key part of the engine and that the manufacturing and assembly processes have a great impact on the overall quality of the engine.The following table lists the key process control points for this

Bolt is the basic unit of data processing in topology, and also a programming unit for the process of Storm . All the processing in the topology is done in these bolts. Bolts can send data items to multiple data streams (stream). Programmers can first declare multiple streams using the Declarestream () method of the Outputfieldsdeclarer class, specifying the stream to which the data will be sent. The data is then sent using the Spoutoutputcollector em

Bolt is a unit of data processing in topology and a programming unit for the process of storm. All of the processing in topology is done in these bolts, and programmers can implement custom processes such as filtering, functions, aggregation, joins, and so on. In the case of complex computational processes, multiple steps are often required and multiple bolts are used.Bolts can send data items to multiple data streams (stream). Programmers can first u

Guid: that is, globally unique identifier (globally unique identifier) is also called UUID (universally unique identifier ). Therefore, the guid is the UUID. GUID is a 128-bit long number, which is generally expressed in hexadecimal notation.AlgorithmThe core idea is to combine the machine's Nic, local time, and a random number to generate a guid. Theoretic

About Storm's spout, bolt structure diagram 　　 The Green section is our most commonly used and relatively simple part. The red part is related to the transaction and will be explained in a later article. basecomponent is the "lazy" class that storm provides. Why do you say that, it and its subclasses are more or less implementing some of the methods of their interface definitions. This allows us to inherit the class directly, rather than writing all t

Because in the work based on Thunderbolt bolt development is IM products, need to implement the function of custom user picture.But Bolt in the image of the default stretch sawtooth effect is very obvious, so that they implement the image stretching function, the code has been shared, to see: "Thunderbolt bolt image stretching unclear solution."However, in the us

Bolt does not provide the official IDE, lack of strong code hints and auto-completion, notepad++ writing interface and script more laborious.notepad++ has a quicktext plug-in that supports multi-language auto-completion and can support bolt XML and Jqbolt LUA code in a simple configuration.After configuring the effect, enter the keyword, ctrl+enter auto completion:Here's how to configure this:1, download th

, typically the implementation of this method is to remove messages from Message Queuing to prevent re-sending. void Fail (Object msgid) A callback method that handles a tuple failure, and typically the implementation of this method is to put the message back in the message queue and then re-send it later in time. Nexttuple () The storm framework calls this method all the time, and the output is stepless to Outputcollector. This method should be non-blocking. Nexttuple,ack and fail are called in

. According to the logic, we want to have its emit multiple messages of different emaildeliverstatus objects. But in fact, this is not the case because storm's emit operations are not executed immediately, The above Code is based on the assumption that after emit is called, storm will immediately send messages. If you follow the preceding statement, bolts will find that multiple messages in the for loop received by the receiver are repeated for multiple times in the last message. Storm does

The effect of the image stretching in the Thunderbolt Bolt Library is more severe, and is often caused by aliasing:1, in the use of Imageobject, DrawMode for 1 stretch mode;2, using the stretch function of bitmap class to stretch the image;Although Imageobject has the AntiAlias attribute to support anti-aliasing, there is no particularly significant optimization effect after setup.The way to solve the aliasing is to write the tensile function in C + +
