      • clearAndEnsureCapacity

        public static java.nio.ByteBuffer clearAndEnsureCapacity​(java.nio.ByteBuffer buffer,
                                                         int elements)
        Ensure the buffer's capacity is large enough to hold a given number of elements. If the input buffer is not large enough, a new buffer is allocated and returned.
        Parameters:
        elements - The required number of elements to be appended to the buffer.
        buffer - The buffer to check or null if a new buffer should be allocated.
        Returns:
        Returns the same buffer or a new buffer with the given capacity.

      • clearAndEnsureCapacity

        public static java.nio.CharBuffer clearAndEnsureCapacity​(java.nio.CharBuffer buffer,
                                                         int elements)
        Ensure the buffer's capacity is large enough to hold a given number of elements. If the input buffer is not large enough, a new buffer is allocated and returned.
        Parameters:
        elements - The required number of elements to be appended to the buffer.
        buffer - The buffer to check or null if a new buffer should be allocated.
        Returns:
        Returns the same buffer or a new buffer with the given capacity.

      • toString

        public static java.lang.String toString​(java.nio.ByteBuffer buffer,
                                        java.nio.charset.Charset charset)
        Parameters:
        buffer - The buffer to convert to a string.
        charset - The charset to use when converting bytes to characters.
        Returns:
        A string representation of buffer's content.

      • toString

        public static java.lang.String toString​(java.nio.CharBuffer buffer)

      • toArray

        public static byte[] toArray​(java.nio.ByteBuffer buffer)
        Parameters:
        buffer - The buffer to read from.
        Returns:
        Returns the remaining bytes from the buffer copied to an array.

      • sharedPrefixLength
