      • print

        public static java.lang.String print​(boolean val)
        Converts a boolean value into a strict representation of it.
        Parameters:
        val - is the boolean input value
        Returns:
        a string representing the boolean value.

      • parse

        public static boolean parse​(java.lang.String rep)
        Converts a boolean string representation into a boolean value. Representations may include non-negative integers, where only 0 means false. Other valid string representations of true include: 
         true
 yes
 on
        Any other string representation is taken to mean false
        Parameters:
        rep - is the input string representing a boolean value.
        Returns:
        a boolean value from the representation.

      • parse

        public static boolean parse​(java.lang.String rep,
                            boolean deflt)
        Converts a boolean string representation into a boolean value. Representations may include non-negative integers, where only 0 means false. Other valid string representations of true include: 
         true
 yes
 on
        Other valid string representations of false include, besides the numerical zero: 
         false
 no
 off
        Any other string representation is taken to mean the boolean value indicated by the paramater deflt.
        Parameters:
        rep - is the input string representing a boolean value.
        deflt - is the deflt value to use in case rep does not represent a valid boolean value.
        Returns:
        a boolean value from the representation.
