Constructor Detail

ServerObject

protected ServerObject(RemoteAdapterFactory factory)
                throws java.rmi.RemoteException

Creates a basic server adapter that uses the given factory to create new adapters.

Parameters:

factory - remote adapter factory

Throws:

java.rmi.RemoteException - on RMI errors

Method Detail

getFactory

protected RemoteAdapterFactory getFactory()

Returns the remote adapter factory used to create new adapters.

Returns:

remote adapter factory

getRepositoryException

protected javax.jcr.RepositoryException getRepositoryException(javax.jcr.RepositoryException ex)

Returns a cleaned version of the given exception. In some cases the underlying repository implementation may throw exceptions that are either unserializable, use exception subclasses that are only locally available, contain references to unserializable or only locally available classes. This method returns a cleaned version of such an exception. The returned exception contains only the message string from the original exception, and uses the public JCR exception class that most specifically matches the original exception.

Parameters:

ex - the original exception

Returns:

clean exception

getRemoteItem

protected RemoteItem getRemoteItem(javax.jcr.Item item)
                            throws java.rmi.RemoteException

Utility method for creating a remote reference for a local item. Unlike the factory method for creating remote item references, this method introspects the type of the local item and returns the corresponding node, property, or item remote reference using the remote adapter factory.

If the item, this method calls the getRemoteNode(Node) to return the correct remote type.

Parameters:

item - local node, property, or item

Returns:

remote node, property, or item reference

Throws:

java.rmi.RemoteException - on RMI errors

getRemoteNode

protected RemoteNode getRemoteNode(javax.jcr.Node node)
                            throws java.rmi.RemoteException

Utility method for creating a remote reference for a local node. Unlike the factory method for creating remote node references, this method introspects the type of the local node and returns the corresponding node, version, or version history remote reference using the remote adapter factory.

Parameters:

node - local version, versionhistory, or normal node

Returns:

remote node, property, or item reference

Throws:

java.rmi.RemoteException - on RMI errors

getRemoteNodeTypeArray

protected RemoteNodeType[] getRemoteNodeTypeArray(javax.jcr.nodetype.NodeType[] types)
                                           throws java.rmi.RemoteException

Utility method for creating an array of remote references for local node types. The remote references are created using the remote adapter factory.

A null input is treated as an empty array.

Parameters:

types - local node type array

Returns:

remote node type array

Throws:

java.rmi.RemoteException - on RMI errors
