      • isAnyShape

        public boolean isAnyShape()

      • getSamples

        public long getSamples()
        Returns:
        The number of inputs this TokenStream has captured.

      • getRegExp

        public java.lang.String getRegExp​(boolean fitted)
        Get the 'best' Regular Expression we can based on the set of TokenStreams.
        Parameters:
        fitted - If true the Regular Expression should be a 'more closely fitted' Regular Expression.
        Returns:
        The 'best' Regular Expression we can based on the set of TokenStreams, or null if nothing clever can be discerned.

      • matches

        public boolean matches​(java.lang.String regExp)
        Check if the TokenStreams (i.e. if all member TokenStream's) match the supplied Regular Expression.
        Parameters:
        regExp - The Regular Expression to match.
        Returns:
        True if the TokenStreams match the supplied Regular Expression.
