Method Detail
addURL
public void addURL(java.lang.String url) throws ServiceNotFoundException
- Appends the specified URL to the list of URLs to search for classes and resources.
Parameters:
- url - the URL to be appended
Throws:
- ServiceNotFoundException - The specified URL is malformed.
addURL
public void addURL(java.net.URL url)
- Appends the specified URL to the list of URLs to search for classes and resources.
Parameters:
- url - the URL to be appended
getLibraryDirectory
public java.lang.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.
getMBeansFromURL
public java.util.Set getMBeansFromURL(java.lang.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 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
public java.util.Set getMBeansFromURL(java.net.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 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.
getURLs
public java.net.URL[] getURLs()
- Returns the search path of URLs for loading classes and resources.
getResource
public java.net.URL getResource(java.lang.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
public java.io.InputStream getResourceAsStream(java.lang.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
public java.util.Enumeration getResources(java.lang.String name) throws java.io.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 the doesn't have access to will not be in the enumeration.
setLibraryDirectory
public void setLibraryDirectory(java.lang.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.
