WebViewProvider

public interface WebViewProvider
WebView backend provider interface: this interface is the abstract backend to a WebView instance; each WebView object is bound to exactly one WebViewProvider object which implements the runtime behavior of that WebView. All methods must behave as per their namesake in {@link WebView}, unless otherwise noted.
hide
Not part of the public API; only required by system implementors.

no further method calls are made to it.
