🧱 Part

Part represents the component type of a CPE identifier — the first attribute of every CPE, distinguishing applications (a), hardware (h), and operating systems (o). This module declares the Part struct, the three predefined Part values, and the inspection methods on Part.

Type: Part

type Part struct {
    ShortName   string
    LongName    string
    Description string
}

Field	Type	Description
ShortName	string	One-character short name used in CPE URIs: a, h, or o
LongName	string	Full name: Application, Hardware, or Operation System
Description	string	Human-readable description of the component type

Variables

var PartApplication = &Part{
    ShortName:   "a",
    LongName:    "Application",
    Description: "表示软件应用程序，包括但不限于桌面应用、服务器应用、移动应用等",
}

var PartHardware = &Part{
    ShortName:   "h",
    LongName:    "Hardware",
    Description: "表示物理硬件设备，包括但不限于网络设备、服务器、存储设备等",
}

var PartOperationSystem = &Part{
    ShortName:   "o",
    LongName:    "Operation System",
    Description: "表示操作系统，用于管理计算机硬件与软件资源的系统软件",
}

The three predefined Part values, returned as pointers. Use them to set the Part field of a CPE struct (dereference when assigning by value, e.g. *cpeskills.PartApplication).

Note: the variable name is PartOperationSystem (matching the source spelling), not PartOperatingSystem.

❓ IsANY

func (p Part) IsANY() bool

Reports whether the part is the logical ANY value, i.e. its ShortName is *.

Return	Type	Description
#1	bool	true if ShortName == "*"

p := *cpeskills.PartApplication
fmt.Println(p.IsANY()) // false

❓ IsNA

func (p Part) IsNA() bool

Reports whether the part is the logical NA value, i.e. its ShortName is -.

Return	Type	Description
#1	bool	true if ShortName == "-"

p := Part{ShortName: "-"}
fmt.Println(p.IsNA()) // true

✔️ IsSet

func (p Part) IsSet() bool

Reports whether the part has a real value: ShortName is non-empty, non-ANY, and non-NA.

Return	Type	Description
#1	bool	true if the part is a concrete value

p := *cpeskills.PartApplication
fmt.Println(p.IsSet()) // true

🧹 Normalize

func (p Part) Normalize() string

Returns the lowercased ShortName.

Return	Type	Description
#1	string	The lowercased short name

p := Part{ShortName: "A"}
fmt.Println(p.Normalize()) // a
