Warnings
All Implemented Interfaces:
Serializable, Localized

public final class Warnings extends Object implements Localized, Serializable
Warnings that occurred during a Well Known Text (WKT) parsing or formatting. Information provided by this object include:
  • Recoverable exceptions.
  • At formatting time, object that can not be formatted in a standard-compliant WKT.
  • At parsing time, unknown keywords.
Example: after parsing the following WKT:
GeographicCRS[“WGS 84”,
  Datum[“World Geodetic System 1984”,
    Ellipsoid[“WGS84”, 6378137.0, 298.257223563, Intruder[“some text here”]]],
    PrimeMeridian[“Greenwich”, 0.0, Intruder[“other text here”]],
  AngularUnit[“degree”, 0.017453292519943295]]
a call to WKTFormat​.get­Warnings() would return a Warnings instance with the following information:

  • Method Details

    • getLocale

      public Locale getLocale()
      Returns the locale in which warning messages are reported by the default to­String() method. This is not necessarily the same locale than the one used for parsing and formatting dates and numbers in the WKT.
      Specified by:
      get­Locale in interface Localized
      Returns:
      the locale or warning messages are reported.
    • getRootElement

      public String getRootElement()
      Returns the name of the root element being parsed or formatted. If the parsed of formatted object implement the Identified­Object interface, then this method returns the value of Identified­Object​.get­Name()​.get­Code(). Otherwise this method returns a simple class name.
      Returns:
      the name of the root element, or null if unknown.
    • getNumMessages

      public final int getNumMessages()
      Returns the number of warning messages.
      Returns:
      the number of warning messages.
    • getMessage

      public String getMessage(int index)
      Returns a warning message.
      Parameters:
      index - 0 for the first warning, 1 for the second warning, etc. until get­Num­Messages() - 1.
      Returns:
      the i-th warning message.
    • getException

      public Exception getException(int index)
      Returns the exception which was the cause of the message at the given index, or null if none.
      Parameters:
      index - the value given to get­Message(int).
      Returns:
      the exception which was the cause of the warning message, or null if none.
    • getExceptions

      public Set<Exception> getExceptions()
      Returns the non-fatal exceptions that occurred during the parsing or formatting. If no exception occurred, returns an empty set.
      Returns:
      the non-fatal exceptions that occurred.
    • getExceptionSource

      public String[] getExceptionSource(Exception ex)
      Returns the keywords of the WKT element where the given exception occurred, or null if unknown. If this method returns a non-null array, then source[0] is the keyword of the WKT element where the exception occurred and source[1] is the keyword of the parent of source[0].
      Note: in other words, this method returns the tail of the path to the WKT element where the exception occurred, but with path elements stored in reverse order.
      Parameters:
      ex - the exception for which to get the source.
      Returns:
      the keywords of the WKT element where the given exception occurred, or null if unknown.
    • getUnknownElements

      public Set<String> getUnknownElements()
      Returns the keywords of all unknown elements found during the WKT parsing.
      Returns:
      the keywords of unknown WKT elements, or an empty set if none.
    • getUnknownElementLocations

      public Collection<String> getUnknownElementLocations(String element)
      Returns the keyword of WKT elements that contains the given unknown element. If the given element is not one of the value returned by get­Unknown­Elements(), then this method returns null.

      The returned collection elements are in no particular order.

      Parameters:
      element - the keyword of the unknown element.
      Returns:
      the keywords of elements where the given unknown element was found.
    • toString

      public String toString()
      Returns a string representation of the warning messages in the formatter locale. The locale used by this method is given by get­Locale().
      Overrides:
      to­String in class Object
      Returns:
      a string representation of the warning messages.
    • toString

      public String toString(Locale locale)
      Returns a string representation of the warning messages in the given locale. This method formats the warnings in a bullet list.
      Parameters:
      locale - the locale to use for formatting warning messages.
      Returns:
