Class Context

java.lang.Object

org.usb4java.Context

public final class Context
extends Object

Structure representing a libusb session. The concept of individual libusb sessions allows for your program to use two libraries (or dynamically load two modules) which both independently use libusb. This will prevent interference between the individual libusb users - for example LibUsb.setDebug(Context, int) will not affect the other user of the library, and LibUsb.exit(Context) will not destroy resources that the other user is still using. Sessions are created by LibUsb.init(Context) and destroyed through LibUsb.exit(Context). If your application is guaranteed to only ever include a single libusb user (i.e. you), you do not have to worry about contexts: pass NULL in every function call where a context is required. The default context will be used.
