LibraryLoader

Kotlin |Java

@UnstableApi
public abstract class LibraryLoader

Configurable loader for native libraries.

Summary

Public fields
`boolean`	`isAvailable`

Public constructors
`LibraryLoader(String[] libraries)`

Public methods
`synchronized boolean`	`isAvailable()` Returns whether the underlying libraries are available, loading them if necessary.
`synchronized void`	`setLibraries(String[] libraries)` Overrides the names of the libraries to load.

Protected methods
`abstract void`	`loadLibrary(String name)` Should be implemented to call `System.loadLibrary(name)`.

Public fields

isAvailable

public boolean isAvailable

Public constructors

LibraryLoader

public LibraryLoader(String[] libraries)

Parameters
`String[] libraries`	The names of the libraries to load.

Public methods

isAvailable

synchronized public boolean isAvailable()

Returns whether the underlying libraries are available, loading them if necessary.

setLibraries

synchronized public void setLibraries(String[] libraries)

Overrides the names of the libraries to load. Must be called before any call to isAvailable.

Protected methods

loadLibrary

protected abstract void loadLibrary(String name)

Should be implemented to call System.loadLibrary(name).

It's necessary for each subclass to implement this method because loadLibrary uses reflection to obtain the calling class, which is then used to obtain the class loader to use when loading the native library. If this class were to implement the method directly, and if a subclass were to have a different class loader, then loading of the native library would fail.

Parameters
`String name`	The name of the library to load.
