Method Detail

updateFromZip

public void updateFromZip(@NotNull
                          @NotNull org.apache.sling.api.resource.ResourceResolver resolver,
                          @NotNull
                          @NotNull InputStream rawZipInputStream,
                          @NotNull
                          @NotNull String nodePath)
                   throws IOException,
                          javax.jcr.RepositoryException

Reads a ZIP from the input stream and updates the resources at the path of the entries of the zip file so that they are identical to the stream, ignoring / updating metadata.

Make subtree equivalent to a ZIP in vault format. General strategy: we update the attributes of all nodes according to the XML documents, creating nonexistent nodes along the way, and make node which nodes were present, and which were changed. In a second pass, we recurse through the JCR tree again, delete nodes that were not present and update the lastModified properties of nodes, below which there were changes.

Specified by:

updateFromZip in interface SourceUpdateService

Parameters:

resolver - the resolver we write to

rawZipInputStream - contains a zip with the data to import. It needs to contain the actual content to import below jcr_root. E.g. if nodePath is /content/whatever, the zip contains the relevant content below jcr_root/content/whatever/somepath

nodePath - the path of the node we want to update

Throws:

IOException

javax.jcr.RepositoryException

makeTempdir

protected org.apache.sling.api.resource.Resource makeTempdir(org.apache.sling.api.resource.ResourceResolver resolver)
                                                      throws javax.jcr.RepositoryException

Throws:

javax.jcr.RepositoryException

isArray

protected boolean isArray(Object value)
