        The module reference (of JPMS type ModuleReference).

      • getLayer

        public java.lang.Object getLayer()
        Returns:

      • getDescriptor

        public java.lang.Object getDescriptor()
        Returns:
        The module descriptor, i.e. getReference().descriptor() (of JPMS type ModuleDescriptor).

      • getPackages

        public java.util.List<java.lang.String> getPackages()

      • getLocationStr

        public java.lang.String getLocationStr()
        Returns:
        The module location as a string, i.e. getReference().location().toString(). Returns null for modules that do not have a location.

      • getLocationFile

        public java.io.File getLocationFile()
        Returns:
        The module location as a File, i.e. new File(getReference().location()). Returns null for modules that do not have a location, or for system ("jrt:") modules.

        Get the raw version string of the module, or null if the module did not provide one.
        Returns:
        The raw version of the module, obtained by ModuleReference#rawVersion().orElse(null).

      • isSystemModule

        public boolean isSystemModule()
        Returns:
        true if this module's location is a non-"file:" (i.e. "jrt:") URI, or if it has no location URI, or if it uses the (null) bootstrap ClassLoader, or if the module name starts with a system prefix ("java.", "jre.", etc.).

      • getClassLoader

        public java.lang.ClassLoader getClassLoader()
        Returns:
        The classloader for the module, i.e. moduleLayer.findLoader(getReference().descriptor().name()).
