Class ArchUtils

  • public class ArchUtils
extends java.lang.Object
    An utility class for the os.arch System Property. The class defines methods for identifying the architecture of the current JVM.

    Important: The os.arch System Property returns the architecture used by the JVM not of the operating system.

    Since:
    3.6

        private static void addProcessor​(java.lang.String key,
                                 Processor processor)
        Adds the given Processor with the given key String to the map.
        Parameters:
        key - The key as String.
        processor - The Processor to add.
        Throws:
        java.lang.IllegalStateException - If the key already exists.

      • addProcessors

        private static void addProcessors​(Processor processor,
                                  java.lang.String... keys)
        Adds the given Processor with the given keys to the map.
        Parameters:
        keys - The keys.
        processor - The Processor to add.
        Throws:
        java.lang.IllegalStateException - If the key already exists.

      • getProcessor

        public static Processor getProcessor()
        Returns a Processor object of the current JVM.

        Important: The os.arch System Property returns the architecture used by the JVM not of the operating system.

        Returns:
        A Processor when supported, else null.

      • getProcessor

        public static Processor getProcessor​(java.lang.String value)
        Returns a Processor object the given value String. The String must be like a value returned by the os.arch System Property.
        Parameters:
        value - A String like a value returned by the os.arch System Property.
        Returns:
        A Processor when it exists, else null.
