getValue

getValue(audienceID, configData, arguments)

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

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;
}
