Method Detail

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 interfaceResourceLoader
- Returns:
- the name of the root
-
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 interfaceResourceLoader
- Parameters:
fileName
- the fileName of the class, e.g. for the classorg.jboss.modules.ResourceLoader
the fileName will beorg/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 interfaceResourceLoader
- 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 interfaceResourceLoader
- Parameters:
name
- the resource name- Returns:
- the resource, or
null
if it is not available
-
getLibrary
public java.lang.String getLibrary(java.lang.String name)
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 interfaceResourceLoader
- 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 interfaceResourceLoader
- Returns:
- the resource paths
-
iterateResources
public java.util.Iterator<Resource> iterateResources(java.lang.String startPath, boolean recursive)
Description copied from interface:IterableResourceLoader
Enumerate all the resources under the given path. The given path name is relative to the root of the resource loader. If the path "escapes" the root via..
, such segments will be consumed. If the path is absolute, it will be converted to a relative path by dropping the leading/
.- Specified by:
iterateResources
in interfaceIterableResourceLoader
- Parameters:
startPath
- the path to search underrecursive
-true
to recursively descend into subdirectories,false
to only read this path- Returns:
- the resource iterator (possibly empty)
-
close
public void close()
Description copied from interface:ResourceLoader
Closes this resource, relinquishing any underlying resources. This method is invoked automatically on objects managed by thetry
-with-resources statement.- Specified by:
close
in interfacejava.lang.AutoCloseable
- Specified by:
close
in interfaceResourceLoader
-
getLocation
public java.net.URI getLocation()
Description copied from interface:ResourceLoader
Get the base location of the resources in this loader (if any). If the location is not known, or the resource loader does not support locations, or the resource loader does not support this method,null
is returned.- Specified by:
getLocation
in interfaceResourceLoader
- Returns:
- the base location of the resources in this loader, or
null
if not available
