public class DynamicContentTargeter
extends GenericService
implements Targeter, atg.targeting.RepositoryTargeter, atg.targeting.ContentHistoryManager, atg.targeting.PCCEditableComponent, atg.targeting.overrides.TargetingObjectsFactory<atg.targeting.RuleBasedRepositoryTargeter>

This implementation of Targeter exists primarily for use with the Dynamo Personalization Control Center (aka PCC, the business user's interface to targeting in the Dynamo 4 personalization system).

It is like RuleBasedRepositoryTargeter in that it performs rule-based targeting over a Repository, but it adds a number of additional features including "rule breaks" (the ability to cascade through multiple rulesets and stop when any one of them returns content) and the ability to say that this targeter should suppress repository items that have already been seen during this session.

To keep the UI manageable, DynamicContentTargeters generally specify a restricted subset of rules that are easy to parse and easy to display and edit in a graphical user interface. This restriction is enforced only at the GUI level, not in the targeter implementation, but if you construct a DynamicContentTargeter by hand whose rules don't fit the expected pattern, the UI will be unable to cope with it. Caveat emptor.

target

public java.lang.Object[] target(NameResolver pNameResolver)
                          throws atg.targeting.TargetingException

Performs a targeting operation, returning an array of "target" objects. The NameResolver argument carries information about the source objects associated with the targeting operation - the "context" of the targeting operation.

Returns null if no items are found matching the targeting criteria.

This method automatically cascades down rulesets. If a ruleset returns no suitable items or if all items returned have passed their impression limits, then the targeting operation will automatically try subsequent rulesets. It returns null only after all rulesets have been exhausted.

Specified by:

target in interface Targeter

Throws:

TargetingException - if a problem was encountered during the targeting operation

target

public java.lang.Object[] target(NameResolver pNameResolver,
                                 int pMaxNumber)
                          throws atg.targeting.TargetingException

Performs a targeting operation, returning an array of "target" objects containing at most pMaxNumber entries. The NameResolver argument carries information about the source objects associated with the targeting operation - the "context" of the targeting operation.

Returns null if no items are found matching the targeting criteria.

This method automatically cascades down rulesets. If a ruleset returns no suitable items or if all items returned have passed their impression limits, then the targeting operation will automatically try subsequent rulesets. It returns null only after all rulesets have been exhausted.

Specified by:

target in interface Targeter

Parameters:

pMaxNumber - the maximum number of elements to return; if -1, the entire result set will be retrieved

Throws:

TargetingException - if a problem was encountered during the targeting operation

target

public java.lang.Object[] target(NameResolver pNameResolver,
                                 int pStartIndex,
                                 int pMaxNumber)
                          throws atg.targeting.TargetingException

Performs a targeting operation, returning an array of "target" objects, beginning at the starting index of the entire result set, and containing at most pMaxNumber elements. The NameResolver argument carries information about the source objects associated with the targeting operation - the "context" of the targeting operation.

This method performs cascading differently from the other target methods of this class. In particular, it does not use impression limits to trigger cascading behavior.

Rulesets are tried in turn until one of them produces a non-empty set of items. That set is then filtered by impression limit, and the result is immediately returned.

If the filtering process removes all items from the initial result set this method immediately returns null, where the other targeting methods would automatically try the next available ruleset. Keep this difference in mind when deciding which form of target to call.

Specified by:

target in interface Targeter

Parameters:

pStartIndex - the starting index; must be >= 0

pMaxNumber - the maximum number of elements to return; if -1, the entire result set starting at index pStartIndex will be retrieved

Throws:

TargetingException - if a problem was encountered during the targeting operation

public void registerContentShown(NameResolver pNameResolver,
                                 RepositoryItem pItem)

Stop this dynamic content targeting service.

Overrides:

doStopService in class GenericService

start

public void start()
           throws atg.targeting.TargetingException

Prepare this targeter for use. This method is called by doStartService to perform any generic initialization required by this service. Any initialization that depends on this object actually being a Nucleus component should be done directly in doStartService.

This allows the object to be instantiated either as a Nucleus component or stand-alone. For example, one could instantiate a DynamicContentTargeter as follows:

DynamicContentTargeter t = new DynamicContentTargeter(); t.setRepository(...); t.setRepositoryViewName(...); t.setRulesets(...); t.start();

Throws:

TargetingException - if the object had a problem starting up
