Class NativeImpl

java.lang.Object

com.google.gwt.typedarrays.shared.TypedArrays.Impl

com.google.gwt.typedarrays.client.NativeImpl

Direct Known Subclasses:

NativeImplEmulClamped, NativeImplFull

public class NativeImpl
extends TypedArrays.Impl

The default implementation class, which assumes that Typed Arrays might be supported and does runtime checks where necessary, substituting emulated implementations of DataView and Uint8ClampedArray where they are missing.

This can be replaced with a version which avoids runtime checks where possible for efficiency.

protected boolean checkUint8ClampedArraySupport()

runtimeSupportCheck

protected boolean runtimeSupportCheck()

Description copied from class: TypedArrays.Impl

Check if the current environment actually does support typed arrays (including emulation). There is no partial support, so if true is returned, there must be acceptable implementations for all of the createXXX methods.

Overrides:

runtimeSupportCheck in class TypedArrays.Impl

Returns:

true if the current environment actually does support typed arrays
