Duplicate data deletion (De-duplication, DDD) is one of the advanced features of networked storage devices, which can effectively reduce the storage space occupied by duplicate data and increase the space utilization of storage devices.
The data de-duplication feature for NetApp filer is called a-sis. When applying the command line in the following example, replace the/vol/vol1 with your own volume name.

Delphi's component reading and writing mechanism (i.)I. Introduction to streaming objects (stream) and read-write objects (Filer)Object-based data management plays an important role in object-oriented programming. In Delphi, the way to support the object-type data management is one of its main features.Delphi is an integrated development environment that combines object-oriented visual design with object-oriented language. The core of Delphi is the co

standardized and incorporated into the standard library through JSR 269, and the APT tool has been seamlessly integrated into the Java compiler tool JAVAC. Java 6 provides an abstract class javax.annotation.processing.AbstractProcessor that has implemented common functionality, and also provides Javax.lang.model packages. Annotation Processor API

Realization principle and application of 20.2 read-write Object
Read-Write objects (Filer) include Tfiler objects, Treader objects, and Twriter objects. The Tfiler object is the underlying object of file reading and writing, and is used primarily in Treader and twriter applications. Both Treader and Twriter objects are inherited directly from the Tfiler object. The Tfiler object defines the basic properties and methods of the
Properties and methods of 20.2.1.1 Tfiler objects
1. Root Property
Statement: Property root:tcomponent;
The root property indicates to the Filer object which object in the read-write object is the root or primary owner. The Rootcomponent and Writerootcomponent methods set the value of root before reading and writing parts and their own parts.
2. Ancestor Properties
Statement: Property ancestor:tpersistent;
The Ancestor property is used to write
Realization principle of 20.2.1.2 Tfiler object
The Tfiler object is the underlying class of the Filer object, and most of the methods it defines are abstract types and are not specifically implemented, and are overridden in Treader and Twrite. But they provide a framework for the Filer object, and it is important to understand it.
1. Implementation of Tfiler object properties
The Tfiler object defines t

) specifically for object data management. In Delphi, these functions have been greatly enhanced. Delphi attributes Object data management classes to stream objects (stream) and Filer objects (Filer) and applies them to all aspects of the visual Part class library (VCL). They provide not only the ability to manage objects in memory, external storage, and Windows resources, but also the functionality of obje
After saving and exiting, run startx to start FVWM.
After FVWM is started, if the first time you use FVWM, the first thought may be the same as me. What is this? It is not easy to see, and there is no function. If you want to use FVWM again like me and don't want to study the configuration script, the easiest way is to install FVWM-themes.

, and after the function returns, the stream's pointer moves after the value type indicator.
Tvaluetype is an enumeration type. Each item stored in the stream of the Filer object has a byte that identifies the type of the item and reads the byte before each item is read to guide which method is invoked to 闱 the item. The value of this byte is one of the value types defined by Tvaluetype.

The Gentoo file Manager, Rox-filer, Xfe, and PCMANFM are among the best non-traditional file management tools on the market that are lightweight, powerful, easy to configure, independent of any particular desktop environment, and easy to maintain. They all have comprehensive graphical capabilities and support for keyboard shortcuts and command-line operations. If you're looking for a file management tool that's a bit different, try these tools. You ca

Earlier, I mentioned. How to package the file as a zip package, then how to unzip the zip file package into a normal file? It is easier to unpack the zip package into a normal package than to package the file as a zip. Because there is a multilevel file compression, there is no multi-level file decompression. In other words, when compressing, you have to plug all the files into the compressed package. Decompression only needs to decompress the first level, the compressed package inside the compr
