tokyocabinet1.4.19 Reading notes (i) Overview of hash database
started a formal study of key-value forms of persistent storage scenarios, the first reading of the project is Tokyo cabinet, version number is 1.4.19.Tokyo Cabinet supports several database forms, including hash database, B + Tree database, fix-length database, table database. So far I have only seen the implementation of the first hash database. This is chosen because the first type of database seems to be the most used

Once the transport key is received by the joining device, it'll proceed to check the ' source ' of this Transport key command. In this case the 64-bit IEEE address is different from 0 's and FF ' s, since the TC exists in this network. The following steps describe the unsecure joinin

Management is a solution to the above problems. At the same time, some technologies can be used in automated testing to help solve similar problems.
Name MappingName ing technology
In Tc (test complete), you can customize names for processes, forms, controls, and other objects, or, in other words, you can map an object to another name.
First, the name ing technology can make your script code more readable. For example, editorwindow is better tha
