Class LocalizationGridException

All Implemented Interfaces:
Serializable

public class LocalizationGridException extends FactoryDataException
Thrown when a localization grid can not be computed, presumably because of a problem with grid data. It may be because some grid coordinates are out of CRS domain of validity, causing either Math­Transform to be thrown or Double​.Na­N coordinate values to be computed.

Additional information on exception cause

It is sometime difficult to determine the root cause of this exception. For example grid points slightly outside the CRS domain of validity will not necessarily cause a failure. A strategy can be to try to build the grid anyway, and in case of failure declare that the grid was maybe too far from CRS domain of validity. Because the potential causes are better known by the code that wants a localization grid instead of the Localization­Grid­Builder class, Localization­Grid­Exception provides a set­Potential­Cause(Char­Sequence) method for allowing top-level code to attach additional information to this exception.

      Parameters:
      cause - the cause, saved for later retrieval by the Throwable​.get­Cause() method.
    • LocalizationGridException

      public LocalizationGridException(String message, Throwable cause)
      Constructs an exception with the specified detail message and cause. The cause is the exception thrown in the underlying database (e.g. IOException or SQLException).

    • setPotentialCause

      public void setPotentialCause(CharSequence details)
      Specifies additional information about what may be the cause of this exception. Example: "The grid spans more than 180° of longitude", which may be a cause of map projection failures.
      Parameters:
      details - a potential cause, or null if none. The type should be String or International­String.
    • getPotentialCause

      public CharSequence getPotentialCause()
      Returns the value given to the last call of set­Potential­Cause(Char­Sequence).
      Returns:
      potential cause, or null if none. The type should be String or International­String.
