Class AccessibilityProvider

javax.accessibility.AccessibilityProvider

public abstract class AccessibilityProvider
extends Object

Service Provider Interface (SPI) for Assistive Technology.

This service provider class provides mappings from the platform specific accessibility APIs to the Java Accessibility API.

Each service provider implementation is named and can be activated via the activate() method. Service providers can be loaded when the default toolkit is initialized.

API Note:

There will typically be one provider per platform, such as Windows or Linux, to support accessibility for screen readers and magnifiers. However, more than one service provider can be activated. For example, a test tool which provides visual results obtained by interrogating the Java Accessibility API can be activated along with the activation of the support for screen readers and screen magnifiers.
