Method Detail

findAndLoad

public void findAndLoad(Class classInJar,
                        String libraryName)

Specified by:

findAndLoad in interface NativeLibraryFinderStrategy

templateGetMappedName

protected String templateGetMappedName(Class classInJar,
                                       String libraryName)

Override to change the mapped name this class uses to search for the native library.

Parameters:

classInJar -

libraryName -

Returns:

mapped name of library

computeDirectoryForClass

public File computeDirectoryForClass(Class classInJar)

Computes the directory where NativeLibraryFinder will search for a native library. If classInJar is a class in a jar file then it will return the dirctory that contains the jar file. This is a common installation setup where foo.jar and foo.dll are installed into the same directory. If the jar file was downloaded via http then this method will return null.

If classInJar is a class that was not contained in a jar file, then this will return the directory that is the root of the class tree. This is the same location as a resource with the path of "/" would return. This is useful if the native library will eventually be packaged as a resource in a jar file, because finding the library directory here will allow the code to skip extracting the native library.

Parameters:

classInJar -

Returns:

the directory that will be searched for native libraries for classInJar or null if classInJar is downloaded.

computeJarFile

protected File computeJarFile(URL url)

setClassAsResourcePath

public void setClassAsResourcePath(String resourceToFind)
