Interface ProtectedNodeImporter

All Superinterfaces:

ProtectedItemImporter

public interface ProtectedNodeImporter
extends ProtectedItemImporter

ProtectedNodeImporter provides means to import protected Nodes and the subtree defined below such nodes.

The import of a protected tree is started by the Importer by calling start(Tree). If the ProtectedNodeImporter is able to deal with that type of protected node, it is in charge of dealing with all subsequent child NodeInfos present below the protected parent until end(Tree) is called. The latter resets this importer and makes it available for another protected import.

Method Detail

start

boolean start(@NotNull
              @NotNull Tree protectedParent)
       throws java.lang.IllegalStateException,
              RepositoryException

Notifies this importer about the existence of a protected node that has either been created (NEW) or has been found to be existing. This importer implementation is in charge of evaluating the nature of that protected node in order to determine, if it is able to handle subsequent protected or non-protected child nodes in the tree below that parent.

Parameters:

protectedParent - A protected node that has either been created during the current XML import or that has been found to be existing without allowing same-name siblings.

Returns:

true If this importer is able to deal with the tree that may be present below the given protected Node.

Throws:

java.lang.IllegalStateException - If this method is called on this importer without having reached end(Tree).

RepositoryException - If an error occurs.

end

void end(@NotNull
         @NotNull Tree protectedParent)
  throws java.lang.IllegalStateException,
         ConstraintViolationException,
         RepositoryException

Informs this importer that the tree to be imported below protectedParent has bee completed. This allows the importer to be reset in order to be able to deal with another call to start(Tree).

If start(Tree) hasn't been called before, this method returns silently.

Parameters:

protectedParent - The protected parent tree.

Throws:

java.lang.IllegalStateException - If end is called in an illegal state.

ConstraintViolationException - If the tree that was imported is incomplete.

RepositoryException - If another error occurs.

startChildInfo

void startChildInfo(@NotNull
                    @NotNull NodeInfo childInfo,
                    @NotNull
                    @NotNull java.util.List<PropInfo> propInfos)
             throws java.lang.IllegalStateException,
                    ConstraintViolationException,
                    RepositoryException

Informs this importer about a new childInfo and it's properties. If the importer is able to successfully import the given information this method returns silently. Otherwise ConstraintViolationException is thrown, in which case the whole import fails.

In case this importer deals with multiple levels of nodes, it is in charge of maintaining the hierarchical structure (see also {#link endChildInfo()}.

If start(Tree) hasn't been called before, this method returns silently.

Parameters:

childInfo -

propInfos -

Throws:

java.lang.IllegalStateException - If called in an illegal state.

ConstraintViolationException - If the given infos contain invalid or incomplete data and therefore cannot be properly handled by this importer.

RepositoryException - If another error occurs.

endChildInfo

void endChildInfo()
           throws RepositoryException

Informs this importer about the end of a child info.

If start(Tree) hasn't been called before, this method returns silently.

Throws:

java.lang.IllegalStateException - If end is called in an illegal state.

ConstraintViolationException - If this method is called before all required child information has been imported.

RepositoryException - If another error occurs.
