getElementCount

protected static int getElementCount(int byteLength,
                                     int elemLength)

elemLength - length of each element in bytes

Returns:

count of elements

mightBeSupported

protected boolean mightBeSupported()

Check if the current environment might possibly support typed arrays.

The default implementation always returns true, and this is intended to be a static check based on deffered-bound parameters.

Returns:

true if the current environment might possibly support typed arrays

runtimeSupportCheck

protected boolean runtimeSupportCheck()

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.

Returns:

true if the current environment actually does support typed arrays
