public static boolean initialize(java.lang.String libraryName)
                          throws java.lang.Exception
```
    Setup any APR internal data structures. This MUST be the first function called for any APR library.
    
    Parameters:
    
    libraryName - the name of the library to load
    
    Returns:
    
    true if the native code was initialized successfully otherwise false
    
    Throws:
    
    java.lang.Exception - if a problem occurred during initialization
  - load
```
@Deprecated
public static void load(java.lang.String filename)
```
    Deprecated.
    Unused. Will be removed in Tomcat 10.1.x
    
    Calls System.load(filename). System.load() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
    
    Parameters:
    
    filename - - absolute path of the native library
  - loadLibrary
```
@Deprecated
public static void loadLibrary(java.lang.String libname)
```
    Deprecated.
    Unused. Will be removed in Tomcat 10.1.x
    
    Calls System.loadLibrary(libname). System.loadLibrary() associates the loaded library with the class loader of the class that called the System method. A native library may not be loaded by more than one class loader, so calling the System method from a class that was loaded by a Webapp class loader will make it impossible for other Webapps to load it. Using this method will load the native library via a shared class loader (typically the Common class loader, but may vary in some configurations), so that it can be loaded by multiple Webapps.
    
    Parameters:
    
    libname - - the name of the native library
