Method Summary

Modifier and Type	Method and Description
void	createProjection(String absNodePath, String sourceName, String externalPath, String alias) Creates an external projection by linking an internal node with an external node, from a given source using an optional alias.
void	removeProjection(String projectionPath) Removes a projection located at the given path, in the workspace which was used to get the federation manager.

Method Detail

createProjection

void createProjection(String absNodePath,
                      String sourceName,
                      String externalPath,
                      String alias)
               throws RepositoryException

Creates an external projection by linking an internal node with an external node, from a given source using an optional alias. If this is the first node linked to the existing node, it will convert the existing node to a federated node.

Parameters:

absNodePath - a non-null string representing the absolute path to an existing internal node.

sourceName - a non-null string representing the name of an external source, configured in the repository.

externalPath - a non-null string representing a path in the external source, where at which there is an external node that will be linked.

alias - an optional string representing the name under which the alias should be created. If not present, the externalPath will be used as the name of the alias.

Throws:

RepositoryException - if the repository cannot perform the operation.

removeProjection

void removeProjection(String projectionPath)
               throws RepositoryException

Removes a projection located at the given path, in the workspace which was used to get the federation manager.

A projection path has the form: [repositoryPath]/[projection alias] as created via createProjection(String, String, String, String)

Parameters:

projectionPath - a non-null String representing the path to a projection

Throws:

IllegalArgumentException - if the projection path does not represent a valid path

PathNotFoundException - if either the repository path or the projection alias are not valid

RepositoryException - if anything unexpected fails
