org.openanzo.client
Class NotificationContainerProxy

java.lang.Object
  org.openanzo.client.NotificationContainerProxy

All Implemented Interfaces:: IContainer

public class NotificationContainerProxy
extends java.lang.Object
implements IContainer
extends java.lang.Object
implements IContainer

NotificationContainerProxy acts as a proxy on top of an IContainer which overlays the underlying data with the data received via the notification service. Data received via the notification service is never added directly to the underlying container. Data remains in this proxy layer until such time as the client replicates with the server, thus getting the current state of the server, and not needing the versions received via notification.All calls to find and contains will contain the results of the underlying container overlaid with the contents of the proxy.

Constructor Summary
`NotificationContainerProxy(DatasetService datasetService, IContainer parentContainer)` Create a new NotificationContainerProxy

Method Summary
`void`	`add(java.util.Iterator<org.openrdf.model.Statement> statements)` Add a set of statements from container
`void`	`add(org.openrdf.model.Resource subj, org.openrdf.model.URI pred, org.openrdf.model.Value obj, org.openrdf.model.Resource context)` Add a new statement with given subj,pred,obj,context
`void`	`add(org.openrdf.model.Statement... statements)` Add one or more statements to container
`void`	`clear()` Delete all statements in container
`void`	`clear(org.openrdf.model.Resource... context)` Delete all statements in container for given contexts
`void`	`close()` Disconnect container from its source and close the container Note: Once a container is closed, it is based on the source of the container's data whether or not subsequent calls to connect will return the same data
`void`	`connect()` Connect container to its source
`boolean`	`contains(org.openrdf.model.Resource s, org.openrdf.model.URI p, org.openrdf.model.Value o, org.openrdf.model.Resource... context)` Return true if the container contains atleast 1 statement that matches the pattern of subj,prop,obj,context
`boolean`	`contains(org.openrdf.model.Statement statement)` Return true if the container contains atleast 1 statement that matches the statement provided
`void`	`delete(java.util.Iterator<org.openrdf.model.Statement> statements)` Delete a set of statements from container
`void`	`delete(org.openrdf.model.Resource subj, org.openrdf.model.URI pred, org.openrdf.model.Value obj, org.openrdf.model.Resource context)` Delete a statement from container
`void`	`delete(org.openrdf.model.Statement... statements)` Delete a set of statements from container
`QueryResult`	`executeQuery(java.util.Set<org.openrdf.model.URI> defaultNamedGraphsIn, java.util.Set<org.openrdf.model.URI> namedGraphsIn, java.lang.String query)` Execute a SPARQL query against the data within this container
`info.aduna.collections.iterators.CloseableIterator<org.openrdf.model.Statement>`	`find(org.openrdf.model.Resource s, org.openrdf.model.URI p, org.openrdf.model.Value o, org.openrdf.model.Resource... context)` Return an iterator over all statements that match the pattern of subj,prop,obj
`java.util.Collection<org.openrdf.model.URI>`	`getContexts()` Get the set of Context URIs that are container within this Container
`INamedGraphEventManager`	`getEventManager()` Return INamedGraphEventManager for this container
`info.aduna.collections.iterators.CloseableIterator<org.openrdf.model.Statement>`	`getStatements()` Get an iterator over all statements within this container
`ITransactionManager`	`getTransactionManager()` Return ITransactionManager for this container
`org.openrdf.model.URI`	`getURI()` Get URI of IContainer
`boolean`	`isClosed()` Return if container is closed
`boolean`	`isConnected()` Return if the container is connected to its source
`boolean`	`isEmpty()` Return if container is empty
`boolean`	`isEmpty(org.openrdf.model.Resource... context)` Return if container is empty for given contexts
`void`	`setEventManager(INamedGraphEventManager eventManager)` Set INamedGraphEventManager for this container
`void`	`setTransactionManager(ITransactionManager transactionQueueManager)` Set ITransactionManager for this container
`int`	`size()` Return number of statements in container
`int`	`size(org.openrdf.model.Resource... context)` Return number of statements in container
