    • Method Detail

      • getBottom

        public double getBottom()
        Returns the bottom of the valid double range.

      • setBottom

        public void setBottom​(double bottom)
        Sets the bottom of the valid double range.

        The default value is the minimum double value.

      • getTop

        public double getTop()
        Returns the top of the valid double range.

      • setTop

        public void setTop​(double top)
        Sets the top of the valid double range.

        The default value is the maximum double value.

      • setRange

        public void setRange​(double bottom,
                     double top)
        Sets the range of valid doubles.

      • validate

        public WValidator.Result validate​(java.lang.String input)
        Validates the given input.

        The input is considered valid only when it is blank for a non-mandatory field, or represents a double within the valid range.

        Overrides:
        validate in class WValidator

      • setInvalidNotANumberText

        public void setInvalidNotANumberText​(java.lang.CharSequence text)
        Sets the message to display when the input is not a number.

        The default value is "Must be a number."

      • setInvalidTooSmallText

        public void setInvalidTooSmallText​(java.lang.CharSequence text)
        Sets the message to display when the number is too small.

        Depending on whether getBottom() and getTop() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be larger than {1}".

      • setInvalidTooLargeText

        public void setInvalidTooLargeText​(java.lang.CharSequence text)
        Sets the message to display when the number is too large.

        Depending on whether getBottom() and getTop() are real bounds, the default message is "The number must be between {1} and {2}" or "The number must be smaller than {2}".

      • setIgnoreTrailingSpaces

        public void setIgnoreTrailingSpaces​(boolean b)
        If true the validator will ignore trailing spaces.

        See Also:
        isIgnoreTrailingSpaces()

      • isIgnoreTrailingSpaces

        public boolean isIgnoreTrailingSpaces()
        Indicates whether the validator should ignore the trailing spaces.

        See Also:
        setIgnoreTrailingSpaces(boolean b)

      • getJavaScriptValidate

        public java.lang.String getJavaScriptValidate()
        Description copied from class: WValidator
        Creates a Javascript object that validates the input.

        The JavaScript expression should evaluate to an object which contains a validate(text) function, which returns an object that contains the following two fields:

        • fields: a boolean valid,
        • a message that indicates the problem if not valid.

        Returns an empty string if the validator does not provide a client-side validation implementationq.

        Overrides:
        getJavaScriptValidate in class WValidator

        WValidator.getInputFilter()
