      • getRootName

        public java.lang.String getRootName()
        Description copied from interface: ResourceLoader
        Get the name of the root represented by this resource loader.
        Specified by:
        getRootName in interface ResourceLoader
        Returns:

      • getClassSpec

        public ClassSpec getClassSpec​(java.lang.String fileName)
                               throws java.io.IOException
        Description copied from interface: ResourceLoader
        Get the class specification for the given class name. If no matching class is found, null is returned.
        Specified by:
        getClassSpec in interface ResourceLoader
        Parameters:
        fileName - the fileName of the class, e.g. for the class org.jboss.modules.ResourceLoader the fileName will be org/jboss/modules/ResourceLoader.class
        Returns:
        the class specification, or null if the named class is not found
        Throws:
        java.io.IOException - if an I/O error occurs
      • getPackageSpec

        public PackageSpec getPackageSpec​(java.lang.String name)
                                   throws java.io.IOException
        Description copied from interface: ResourceLoader
        Get the package specification for the given directory name. Always returns a package specification; this method cannot be used to test for the existence of a package. A package spec should always be acquired from the same resource loader which provided the class specification. The directory name will always be specified using "/" separators.
        Specified by:
        getPackageSpec in interface ResourceLoader
        Parameters:
        name - the directory name
        Returns:
        the package specification
        Throws:
        java.io.IOException - if an I/O error occurs
      • getResource

        public Resource getResource​(java.lang.String name)
        Description copied from interface: ResourceLoader
        Get a resource with the given name. If no such resource is available, null is returned. The resource name will always be specified using "/" separators for the directory segments.
        Specified by:
        getResource in interface ResourceLoader
        Parameters:
        name - the resource name
        Returns:
        the resource, or null if it is not available
      • getLibrary

        Description copied from interface: ResourceLoader
        Get the absolute physical filesystem path for a library with the given name. The resultant path should be path-separated using "/" characters.
        Specified by:
        getLibrary in interface ResourceLoader
        Parameters:
        name - the name
        Returns:
        the path or null if the library is not present
      • getPaths

        public java.util.Collection<java.lang.String> getPaths()
        Description copied from interface: ResourceLoader
        Get the collection of resource paths. Called one time only when the resource loader is initialized. The paths should use "/" characters to separate the path segments.
        Specified by:
        getPaths in interface ResourceLoader
        Returns:
        the resource paths
      • close

        public void close()
        Description copied from interface: ResourceLoader

        Specified by:
        getLocation in interface ResourceLoader
        Returns:
        the base location of the resources in this loader, or null if not available
