Description
Interface Summary | |
---|---|
Batch | The Batch defines an ordered list of of operations that must be
executed at once on the persistent layer. |
ChildInfo | ChildInfo ... |
Event | Event is similar to the regular JCR Event and adds additional
information about the affected item. |
EventBundle | An EventBundle is similar to the
EventIterator interface. |
EventFilter | An EventFilter is applied to the events as generated on the
repository server. |
IdFactory | IdFactory defines methods to construct new ItemId s. |
ItemId | An ItemId identifies an item using a combination of unique ID
and path. |
ItemInfo | The ItemInfo is the base interface of
and . |
LockInfo | LockInfo is used to transport lock information across the SPI
boundary. |
Name | A Name is a combination of a namespace URI and a local part. |
NameFactory | NameFactory ... |
NodeId | NodeId identifies a node on the SPI layer. |
NodeInfo | The NodeInfo provides the basic information required to build
nodes making up the repository hierarchy. |
Path | The Path interface defines the qualified representation of
a JCR path. |
Path.Element | Object representation of a single JCR path element. |
PathFactory | PathFactory ... |
PropertyId | PropertyId identifies a property on the SPI layer. |
PropertyInfo | The PropertyInfo provides the basic information to build a
Property . |
QItemDefinition | QItemDefinition is the qualified SPI representation of
an item definition . |
QNodeDefinition | QNodeDefinition is the qualified SPI representation of
a node definition . |
QNodeTypeDefinition | QNodeTypeDefinition is the qualified SPI representation of a
node type . |
QPropertyDefinition | QPropertyDefinition is the qualified SPI representation of
a property definition . |
QueryInfo | QueryInfo is the the return value of
RepositoryService.executeQuery(SessionInfo, String, String, Map)
which is used to run a query on the RepositoryService . |
QueryResultRow | QueryResultRow represents the SPI equivalent of a query result
row. |
QValue | QValue is the qualified SPI representation of a
jcr value . |
QValueFactory | QValueFactory defines methods to create QValue
instances. |
RepositoryService | The RepositoryService interface defines methods used to
retrieve information from the persistent layer of the repository as well
as the methods that modify its persistent state. |
SessionInfo | SessionInfo is created upon
RepositoryService.obtain(javax.jcr.Credentials, String) or
RepositoryService.obtain(SessionInfo, String) and will be used for
any call on the RepositoryService that requires user and workspace
identification. |
Subscription | Subscription defines a marker interface for an event
subscription. |
XASessionInfo | XASessionInfo extends the SessionInfo and provides
access to the XAResource of the session info. |
Defines the interfaces of the JCR SPI (Service Provider Interface).
The SPI cuts the JCR stack into two parts:RepositoryService.getEvents()
. With every call to this method the repository
is advised to return the events that occurred since the last call. As a
reference to the last retrieved EventBundle
the SessionInfo
contains a bundle identifier
which is automatically updated on each call to RepositoryService.getEvents()
.
While this design allows for a polling implementation on top of the SPI it is
also well suited for a listener based observation implementation on top of the
SPI. With only little thread synchronization overhead events can be acquired
using a timeout
of Long.MAX_VALUE
.
If an SPI implementation does not support observation, the method
RepositoryService.getEvents()
will always throw an
UnsupportedRepositoryOperationException
.
