reportNativeAllocations

public static java.lang.CharSequence reportNativeAllocations()

Generate a brief textual report of outstanding native allocations

getLoadedLibrary

public static java.lang.String getLoadedLibrary()

If initialized, this is the full path of the loaded library

Returns:

path of library

getLibrarySearchNames

public static java.util.List<java.lang.String> getLibrarySearchNames()

Returns:

modifiable list of library search names to be probed on initialize

getLibrarySearchPath

public static java.util.List<java.lang.String> getLibrarySearchPath()

The library search path. This defaults to the directory containing this jar file (if found) followed by all entries on java.library.path. The system default path is implied.

Returns:

modifiable list of library search paths to be probed on initialize
