Method Summary

Modifier and Type	Method and Description
FederatedPortletInvoker	getFederatedInvoker(String federatedId) Returns the registered FederatedPortletInvoker associated with the specified identifier, delegating to the PortletInvokerResolver specified using setPortletInvokerResolver(PortletInvokerResolver) if it's not initially resolved or returns null if a FederatedPortletInvoker is not found after going through the specified NullInvokerHandler resolution mechanism.
Collection<String>	getFederatedInvokerIds() Returns the known portlet invoker identifiers, including resolvable ones (though they might not have been already resolved).
Set<org.gatein.pc.api.Portlet>	getLocalPortlets() Return only the portlets from local federated invokers.
Set<org.gatein.pc.api.Portlet>	getRemotePortlets() Return only the portlets from remote federated invokers.
Collection<String>	getResolvedInvokerIds() Returns only the portlet invoker identifiers of the currently resolved invokers, which might be different from the set potentially resolvable invokers as returned by getFederatedInvokerIds().
boolean	isResolved(String federatedId) Determines whether the FederatedPortletInvoker with the specified identifier has already been resolved.
FederatedPortletInvoker	registerInvoker(String federatedId, org.gatein.pc.api.PortletInvoker registeredInvoker) Registers an invoker.
void	setPortletInvokerResolver(PortletInvokerResolver portletResolver) Specifies which NullInvokerHandler to use to attempt retrieval of a federated invoker when default resolution mechanism cannot find an associated invoker.
void	unregisterInvoker(String federatedId) Unregisters the invoker associated with the specified identifier.

Method Detail

registerInvoker

FederatedPortletInvoker registerInvoker(String federatedId,
                                        org.gatein.pc.api.PortletInvoker registeredInvoker)
                                 throws IllegalArgumentException

Registers an invoker.

Parameters:

federatedId - the invoker id to register

registeredInvoker - the invoker to register

Throws:

IllegalArgumentException - if the invoker is null or already registered

getFederatedInvoker

FederatedPortletInvoker getFederatedInvoker(String federatedId)
                                     throws IllegalArgumentException

Returns the registered FederatedPortletInvoker associated with the specified identifier, delegating to the PortletInvokerResolver specified using setPortletInvokerResolver(PortletInvokerResolver) if it's not initially resolved or returns null if a FederatedPortletInvoker is not found after going through the specified NullInvokerHandler resolution mechanism.

Parameters:

federatedId - the id

Returns:

the invoker

Throws:

IllegalArgumentException - if the id is null

getFederatedInvokerIds

Collection<String> getFederatedInvokerIds()

Returns the known portlet invoker identifiers, including resolvable ones (though they might not have been already resolved).

Returns:

a collection of all the resolvable portlet invoker identifiers

getResolvedInvokerIds

Collection<String> getResolvedInvokerIds()

Returns only the portlet invoker identifiers of the currently resolved invokers, which might be different from the set potentially resolvable invokers as returned by getFederatedInvokerIds().

Returns:

a collection of the currently resolved portlet invoker identifiers

isResolved

boolean isResolved(String federatedId)
            throws IllegalArgumentException

Determines whether the FederatedPortletInvoker with the specified identifier has already been resolved.

Parameters:

federatedId - the identifier of the FederatedPortletInvoker to test for resolution status

Returns:

true if the specified invoker is already resolved, false otherwise

Throws:

IllegalArgumentException - if the specified invoker identifier is not among the known resolvable identifiers as returned by getFederatedInvokerIds()

unregisterInvoker

void unregisterInvoker(String federatedId)

Unregisters the invoker associated with the specified identifier.

Parameters:

federatedId - the identifier of the invoker to unregister

Throws:

IllegalArgumentException - if the identifier is null or no invoker is registered with this identifier

Since:

2.6

getLocalPortlets

                                         throws org.gatein.pc.api.PortletInvokerException

Return only the portlets from local federated invokers.

Returns:

a Set containing only the portlets from local federated invokers.

Throws:

org.gatein.pc.api.PortletInvokerException

getRemotePortlets

Set<org.gatein.pc.api.Portlet> getRemotePortlets()
                                          throws org.gatein.pc.api.PortletInvokerException

Return only the portlets from remote federated invokers.

Returns:

a Set containing only the portlets from remote federated invokers.

Throws:

org.gatein.pc.api.PortletInvokerException

setPortletInvokerResolver

void setPortletInvokerResolver(PortletInvokerResolver portletResolver)

Specifies which NullInvokerHandler to use to attempt retrieval of a federated invoker when default resolution mechanism cannot find an associated invoker.

Parameters:

portletResolver -
