      • getElementCount

        protected static int getElementCount​(int byteLength,
                                     int elemLength)
        Get the number of elements in a number of bytes, throwing an exception if it isn't an integral number.
        Parameters:
        byteLength -
        elemLength - length of each element in bytes
        Returns:
        count of elements
        Throws:
        java.lang.IllegalArgumentException - if byteLength isn't an integral multiple of elemLength

      • 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
