public AbstractImportCommand()

Method Detail

execute

public boolean execute(AbstractContext context)
                throws Exception

Executes this command by calling importResource(org.apache.jackrabbit.server.io.ImportContext, javax.jcr.Node, java.io.InputStream) if the given context is of the correct class.

Specified by:

execute in class AbstractCommand

Parameters:

context - the (import) context.

Returns:

the return value of the delegated method or false;

Throws:

Exception - in an error occurrs

execute

public boolean execute(ImportContext context)
                throws Exception

Executes this command. It checks if this command can handle the content type and delegates it to importResource(org.apache.jackrabbit.server.io.ImportContext, javax.jcr.Node, java.io.InputStream). If the import is successfull, the input stream of the importcontext is cleared.

Parameters:

context - the import context

Returns:

false

Throws:

Exception - if an error occurrs

mkDirs

public static Node mkDirs(ImportContext context,
                          Node root,
                          String relPath)
                   throws RepositoryException

Creates collection recursively.

Parameters:

root -

relPath -

Returns:

Throws:

RepositoryException

setNodeType

public void setNodeType(String nodeType)

Sets the node type

Parameters:

nodeType -

importResource

public abstract boolean importResource(ImportContext ctx,
                                       Node parentNode,
                                       InputStream in)
                                throws Exception

Imports the resource contained in the import context.

Parameters:

ctx -

parentNode -

in -

Returns:

Throws:

Exception

canHandle

public abstract boolean canHandle(String contentType)

Returns true, if this command handles the given content type.

Parameters:
