getMBeansFromURL
Set getMBeansFromURL(String url)
throws ServiceNotFoundException
- Loads a text file containing MLET tags that define the MBeans
to be added to the agent. The location of the text file is
specified by a URL. The text file is read using the UTF-8
encoding. The MBeans specified in the MLET file will be
instantiated and registered by the MBeanServer.
- Parameters:
url - The URL of the text file to be loaded as String object.
- Returns:
- A set containing one entry per MLET tag in the m-let
text file loaded. Each entry specifies either the
ObjectInstance for the created MBean, or a throwable object
(that is, an error or an exception) if the MBean could not be
created.
- Throws:
ServiceNotFoundException - One of the following errors
has occurred: The m-let text file does not contain an MLET tag,
the m-let text file is not found, a mandatory attribute of the
MLET tag is not specified, the value of url is malformed.
getMBeansFromURL
Set getMBeansFromURL(URL url)
throws ServiceNotFoundException
- Loads a text file containing MLET tags that define the MBeans
to be added to the agent. The location of the text file is
specified by a URL. The text file is read using the UTF-8
encoding. The MBeans specified in the MLET file will be
instantiated and registered by the MBeanServer.
- Parameters:
url - The URL of the text file to be loaded as URL object.
- Returns:
- A set containing one entry per MLET tag in the m-let
text file loaded. Each entry specifies either the
ObjectInstance for the created MBean, or a throwable object
(that is, an error or an exception) if the MBean could not be
created.
- Throws:
ServiceNotFoundException - One of the following errors
has occurred: The m-let text file does not contain an MLET tag,
the m-let text file is not found, a mandatory attribute of the
MLET tag is not specified, the value of url is null.
addURL
void addURL(URL url)
- Appends the specified URL to the list of URLs to search for classes and
resources.
- Parameters:
url - the URL to add.
addURL
void addURL(String url)
throws ServiceNotFoundException
- Appends the specified URL to the list of URLs to search for classes and
resources.
- Parameters:
url - the URL to add.
- Throws:
ServiceNotFoundException - The specified URL is malformed.
getURLs
URL[] getURLs()
- Returns the search path of URLs for loading classes and resources.
This includes the original list of URLs specified to the constructor,
along with any URLs subsequently appended by the addURL() method.
- Returns:
- the list of URLs.
getResource
URL getResource(String name)
- Finds the resource with the given name.
A resource is some data (images, audio, text, etc) that can be accessed by class code in a way that is
independent of the location of the code.
The name of a resource is a "/"-separated path name that identifies the resource.
- Parameters:
name - The resource name
- Returns:
- An URL for reading the resource, or null if the resource could not be found or the caller doesn't have adequate privileges to get the
resource.
getResourceAsStream
InputStream getResourceAsStream(String name)
- Returns an input stream for reading the specified resource. The search order is described in the documentation for
getResource(String).
- Parameters:
name - The resource name
- Returns:
- An input stream for reading the resource, or null if the resource could not be found
getResources
Enumeration getResources(String name)
throws IOException
- Finds all the resources with the given name. A resource is some
data (images, audio, text, etc) that can be accessed by class
code in a way that is independent of the location of the code.
The name of a resource is a "/"-separated path name that
identifies the resource.
- Parameters:
name - The resource name.
- Returns:
- An enumeration of URL to the resource. If no resources
could be found, the enumeration will be empty. Resources that
cannot be accessed will not be in the enumeration.
- Throws:
IOException - if an I/O exception occurs when
searching for resources.
getLibraryDirectory
String getLibraryDirectory()
- Gets the current directory used by the library loader for
storing native libraries before they are loaded into memory.
- Returns:
- The current directory used by the library loader.
- See Also:
setLibraryDirectory(java.lang.String)
setLibraryDirectory
void setLibraryDirectory(String libdir)
- Sets the directory used by the library loader for storing
native libraries before they are loaded into memory.
- Parameters:
libdir - The directory used by the library loader.- See Also:
