getValue

The getValue method performs the core functionality of the callout and returns the results. 

getValue(audienceID, configData, arguments)

The getValue method requires the following parameters:

  • audienceID - a value which identifies the audience ID.

  • configData - a map with key-value pairs of configuration data required by the callout.

  • arguments - the arguments required by the callout. Each argument can be a String, Double, Date, or a List of one of these. A List argument can contain null values, however, a List cannot contain, for example, a String and a Double.

    Argument type checking should be done within your implementation.

If the getValue method fails for any reason, it returns CalloutException.

Return value

The getValue method returns a list of Strings.

Example

public List<String> getValue(AudienceId audienceId, Map<String, 
  String> configurationData, Object... arguments) throws CalloutException
{
	Long customerId = (Long) audienceId.getComponentValue("Customer");
	// now query scoreQueryUtility for the credit score of customerId
	Double score = scoreQueryUtility.query(customerId);
	String str = Double.toString(score);
	List<String> list = new LinkedList<String>();
	list.add(str);
	return list;
}
