Class Conversions.Converter

  • Enclosing class:
    Conversions
    public abstract static class Conversions.Converter
extends Object
    A converter converts a value to its representation as a specific target type. Not all target types might be supported for a given value in which case implementations throw an exception. The default implementations of the various conversion methods all operate on the string representation of the underlying value (i.e. call Converter.toString().

        Returns:
        binary representation of the converted value

      • toLong

        public long toLong()
        Convert to long. This default implementation is based on Long.parseLong(String).
        Returns:
        long representation of the converted value
        Throws:
        NumberFormatException

      • toDouble

        public double toDouble()
        Convert to double. This default implementation is based on Double.parseDouble(String).
        Returns:
        double representation of the converted value
        Throws:
        NumberFormatException

      • toCalendar

        public Calendar toCalendar()
        Convert to date. This default implementation is based on ISO8601.parse(String).

        IllegalArgumentException - if the string cannot be parsed into a date

      • toDate

        public String toDate()
        Convert to date. This default implementation delegates to toCalendar() and returns the ISO8601.format(Calendar) value of the calendar.
        Returns:
        date representation of the converted value
        Throws:
        IllegalArgumentException - if the string cannot be parsed into a date

      • toBoolean

        public boolean toBoolean()
        Convert to boolean. This default implementation is based on Boolean.parseBoolean(String).
        Returns:
        boolean representation of the converted value

      • toDecimal

        public BigDecimal toDecimal()
        Convert to decimal. This default implementation is based on new BigDecimal(String).
