      public AbstractFormatValidator(boolean strict)
      Constructs an instance with the specified strict setting.
      Parameters:
      strict - true if strict Format parsing should be used.

  • Method Details

    • format

      public String format(Object value)

      Format an object into a String using the default Locale.

      Parameters:
      value - The value validation is being performed on.
      Returns:
      The value formatted as a String.

    • format

      protected String format(Object value, Format formatter)

      Format a value with the specified Format.

      Parameters:
      value - The value to be formatted.
      formatter - The Format to use.
      Returns:
      The formatted value.

    • format

      public String format(Object value, Locale locale)

      Format an object into a String using the specified Locale.

      Parameters:
      value - The value validation is being performed on.
      locale - The locale to use for the Format.
      Returns:
      The value formatted as a String.

    • format

      public String format(Object value, String pattern)

      Format an object into a String using the specified pattern.

      Parameters:
      value - The value validation is being performed on.
      pattern - The pattern used to format the value.
      Returns:
      The value formatted as a String.

    • format

      public String format(Object value, String pattern, Locale locale)

      Format an object using the specified pattern and/or Locale.

      Parameters:
      value - The value validation is being performed on.
      pattern - The pattern used to format the value.
      locale - The locale to use for the Format.
      Returns:
      The value formatted as a String.

    • getFormat

      protected abstract Format getFormat(String pattern, Locale locale)

      Returns a Format for the specified pattern and/or Locale.

      Parameters:
      pattern - The pattern used to validate the value against or null to use the default for the Locale.
      locale - The locale to use for the currency format, system default if null.
      Returns:
      The NumberFormat to created.

    • isStrict

      public boolean isStrict()

      Indicates whether validated values should adhere strictly to the Format used.

      Typically implementations of Format ignore invalid characters at the end of the value and just stop parsing. For example parsing a date value of 01/01/20x0 using a pattern of dd/MM/yyyy will result in a year of 20 if strict is set to false, whereas setting strict to true will cause this value to fail validation.

      Returns:
      true if strict Format parsing should be used.

    • isValid

      public boolean isValid(String value)

      Validate using the default Locale.

      Parameters:
      value - The value validation is being performed on.
      Returns:
      true if the value is valid.

    • isValid

      public boolean isValid(String value, Locale locale)

      Validate using the specified Locale.

      Parameters:
      value - The value validation is being performed on.
      locale - The locale to use for the Format, defaults to the default
      Returns:
      true if the value is valid.

    • isValid

      public boolean isValid(String value, String pattern)

      Validate using the specified pattern.

      Parameters:
      value - The value validation is being performed on.
      pattern - The pattern used to validate the value against.
      Returns:
      true if the value is valid.

    • isValid

      public abstract boolean isValid(String value, String pattern, Locale locale)
