      • copy

        public static ByteString copy​(ByteString source)
        Copy - if the source is null, this returns null. Otherwise, the ByteString is copied.
        Parameters:
        source - ByteString to be copied

      • substring

        public ByteString substring​(int start,
                            int end)
        Creates a ByteString substring.
        Parameters:
        start - the first character of the substring
        end - the character after the last character of the substring
        Returns:
        the ByteString substring

      • equalsIgnoreCase

        public final boolean equalsIgnoreCase​(byte[] b,
                                      int pos,
                                      int len)
        Check if this ByteString equals the value of the passed arguments
        Parameters:
        b - byte array that holds the value to check against
        pos - first byte in the byte array
        len - length of the value to check against
        Returns:
        true if this ByteString matches, false otherwise

      • equalsIgnoreCase

        public final boolean equalsIgnoreCase​(ByteString c)
        Check if this ByteString is equal to the one passed in the argument.
        Parameters:
        c - ByteString to check against
        Returns:
        true if this ByteString is equal to the c ByteString, false otherwise.

      • equalsAtIgnoreCase

        public final boolean equalsAtIgnoreCase​(byte[] b,
                                        int at)
        Check if this ByteString equals the byte array b, for the length of the byte array, starting at at within this ByteString.

        This extends, some how, startsWidth and endsWidth, avoiding substring.

        Parameters:
        b - byte array that holds the value to check against
        at - first byte in this ByteString
        Returns:
        true if this ByteString matches, false otherwise

      • toString

        public final java.lang.String toString()
        Return a String representation of this ByteString
        Overrides:
        toString in class java.lang.Object
        Returns:
        a String representation of this ByteString

                         int start)
        Find the first byte b in this ByteString.
        Parameters:
        b - byte to find
        start - where to start from
