Method Detail

getAllDefinitions

java.util.Collection<PortletDefinition> getAllDefinitions()

Retrieves all portlet definitions for this deployment including both clones and portlet definitions

Returns:

a collection of portlet definitions from all portlet apps

getAllPortletDefinitions

java.util.Collection<PortletDefinition> getAllPortletDefinitions()

Retrieve all portlet definitions system wide The collection does not include clones

Returns:

a collection of portlet definitions from all portlet apps

getAllCloneDefinitions

java.util.Collection<PortletDefinition> getAllCloneDefinitions()

Retrieve all clone definitions system wide

Returns:

a collection of portlet definitions from all portlet apps

getPortletApplication

PortletApplication getPortletApplication(java.lang.String name)

Retrieves a PortletApplication by it's unique name. We use PortletApplication interface which extends the Pluto PortletApplicationDefinition and adds additional functionallity to it.
This method will always retrieve a fresh instance from the database, bypassing internal cache and therefore should be used when expecting to perform a write operation.

Parameters:

name -

Returns:

PortletApplication

getPortletApplication

PortletApplication getPortletApplication(java.lang.String name,
                                         boolean fromCache)

Retreives a PortletApplication by it's unique name. We use PortletApplication interface which extends the Pluto PortletApplicationDefinition and adds additional functionallity to it.
This method will optionally try to retrieve a shared instance from an internal cache first. If not found it will retrieve a fresh instance from the database (which will also store the instance in the cache for future access).
Because the returned instance might be shared it should only be used for readonly purposes.

Parameters:

name -

fromCache - when true first try to retrieve a shared instance from cache

Returns:

PortletApplication

getPortletApplications

java.util.Collection<PortletApplication> getPortletApplications()

getPortletDefinitionByUniqueName

PortletDefinition getPortletDefinitionByUniqueName(java.lang.String name)

unique name is a string formed by the combination of a portlet's unique within it's parent application plus the parent application's unique name within the portlet container using ":" as a delimiter.
FORMAT: application name::portlet name
EXAMPLE: com.myapp.portletApp1::weather-portlet
This method will always retrieve a fresh instance from the database, bypassing internal cache and therefore should be used when expecting to perform a write operation.

Parameters:

name - portlets unique name.

Returns:

Portlet that matches the unique name

getPortletDefinitionByUniqueName

PortletDefinition getPortletDefinitionByUniqueName(java.lang.String name,
                                                   boolean fromCache)

unique name is a string formed by the combination of a portlet's unique within it's parent application plus the parent application's unique name within the portlet container using ":" as a delimiter.
FORMAT: application name::portlet name
EXAMPLE: com.myapp.portletApp1::weather-portlet
This method will optionally try to retrieve a shared instance from an internal cache first. If not found it will retrieve a fresh instance from the database (which will also store the instance in the cache for future access).
Because the returned instance might be shared it should only be used for readonly purposes.

Parameters:

name - portlets unique name.

fromCache - when true first try to retrieve a shared instance from cache

Returns:

Portlet that matches the unique name

portletApplicationExists

boolean portletApplicationExists(java.lang.String name)

Checks whether or not a portlet application with this name has all ready been registered to the container.

Parameters:

name - portlet application name to check for.

Returns:

boolean true if a portlet application with this name is alreay registered, false if it has not.

portletDefinitionExists

boolean portletDefinitionExists(java.lang.String portletName,
                                PortletApplication app)

Checks whether or not a portlet with this identity has all ready been registered to the PortletApplication.

Parameters:

portletIndentity - portlet indetity to check for.

app - PortletApplication to check .

Returns:

boolean true if a portlet with this identity is alreay registered, false if it has not.
