Method Details

scan

public final D scan(I container,
 String path,
 Scope scope,
 Scanner scanner)
             throws IOException

Throws:

IOException

getContainerDescriptor

protected abstract D getContainerDescriptor(I container,
 ScannerContext scannerContext)

Return the descriptor representing the artifact.

Parameters:

container - The container.

scannerContext - The scanner context.

Returns:

The artifact descriptor.

getEntries

protected abstract Iterable<? extends E> getEntries(I container)
                                             throws IOException

Return an iterable which delivers the entries of the container.

The entries must not contain the relative root element, i.e. "/".

Parameters:

container - The container.

Returns:

The iterable of entries.

Throws:

IOException - If the entries cannot be determined.

getContainerPath

protected abstract String getContainerPath(I container,
 String path)

Return the normalized path to the container.

Parameters:

container - The container.

Returns:

The normalized path.

getRelativePath

protected abstract String getRelativePath(I container,
 E entry)

Return the relative path of an element within the container.

The following conditions must be considered:

• The separator to use is "/".
• The path must start with "/".
• The path must not end with "/".

leaveContainer

protected abstract void leaveContainer(I container,
 D containerDescriptor,
 ScannerContext scannerContext)
                                throws IOException

Destroy the container dependent scope.

Parameters:

container - The container.

containerDescriptor - The container descriptor

scannerContext - The scanner context.
