public interface Platform
Root of the interface hierarchy for architectures, OS, and supported combinations of them.

A platform group (e.g., an architecture or OS) is an interface extending Platform. A leaf platform, e.g., a supported architecture-OS-combination, is a class that implements all the groups that it belongs to. A leaf platform class must be non-abstract and must have a no-argument constructor. It is good practice to make leaf platform classes final (to prevent accidental subclassing) and to avoid state (i.e., no fields).

The annotation Platforms restricts a type, method, or field to certain platform groups or leaf platforms.

This system makes the set of platform groups and leaf platforms extensible. Some standard platforms are defined as inner classes.

    Modifier and Type
    Method
    Description
    default String
    getArchitecture()
    Returns the string representing Platform's architecture name.
    default String
    getOS()
    Returns the string representing Platform's OS name.
    static boolean
    includedIn(Class<? extends Platform> platformGroup)
    Returns true if the current platform (the platform that the native image is built for) is included in the provided platform group.

  • Field Details

    • PLATFORM_PROPERTY_NAME

      static final String PLATFORM_PROPERTY_NAME
      The system property name that specifies the fully qualified name of the Platform implementation class that should be used. If the property is not specified, the platform class is inferred from the standard architectures and operating systems specified in this file, i.e., in most cases it is not necessary to use this property.

    • includedIn

      static boolean includedIn(Class<? extends Platform> platformGroup)
      Returns true if the current platform (the platform that the native image is built for) is included in the provided platform group.

      The platformGroup must be a compile-time constant, so that the call to this method can be replaced with the constant boolean result.

    • getOS

      default String getOS()
      Returns the string representing Platform's OS name.

      This method should be implemented either in a final class or as default method in respective OS interface.

      Since:
      21.0

    • getArchitecture

      default String getArchitecture()
      Returns the string representing Platform's architecture name. This value should be the same as desired os.arch system property.

      This method should be implemented either in final class or as default method in respective architecture interface.
