Constructor Detail

CDFException

public CDFException(java.lang.String message)

Takes a text message from the calling program and throws a CDFException.

Parameters:

message - the message to be thrown with CDFException

CDFException

public CDFException(long statusCode)

Takes a status code and throws a CDFException with the message that corresponds to the status code that is passed in.

Parameters:

statusCode - the CDF statusCode to be thrown

CDFException

public CDFException(long statusCode,
                    java.lang.String where)

Takes a status code and throws a CDFException with the message that corresponds to the status code that is passed in. It also specifies where (which routine) the problem was.

Parameters:

statusCode - the CDF statusCode to be thrown

where - the place (routine/method) where the problem occurred

Method Detail

getCurrentStatus

public long getCurrentStatus()

Gets the status code that caused CDFException. This method comes in handy when there are times one may want to examine the cause of the CDFException and determine whether to continue or not.

    try {
         ...

    } catch (CDFException e) {
          if (e.getCurrentStatus() == NO_SUCH_VAR) {
              Variable latitude = Variable.create(cdf, "Latitude",
                                                  CDF_INT1,
                                                  numElements,
                                                  numDims,
                                                  dimSizes,
                                                  recVary,
                                                  dimVary);
              ... 
          }
          else {
             System.out.println ("StatusCode = "+e.getCurrentStatus());
             e.printStackTrace();
          }
    }






Returns:
the status code that caused CDFException

getStatusMsg

public static java.lang.String getStatusMsg(long statusCode)

Get the status text message for the given status code.

Parameters:

statusCode - the status code from which the status text is retrieved

Returns:

the status text message for the given status code
