Method Details

collectResult

public <R,
E extends Throwable> R collectResult(IResolvedFileListProcessor<R,E> handler)
                                        throws E

Description copied from interface: IResolvedFileList

Iterates over all resolved resource items, processes them with the given handler, and returns the combined result of all resource items. Standard use case is to convert errors to hard and soft workflow node errors and return a list of all resolved files.

If you wish to use the standard error behavior for files, use standardFileErrorsSingle or standardFileErrorsMultiple. Otherwise, provide your own processor implementation, or extends the StandardErrorFileListProcessor.

Specified by:

collectResult in interface IResolvedFileList

Type Parameters:

R - Type of the combined result of all resource items.

E - Type of the error that may be thrown when any errors are present.

Parameters:

handler - Handler for processing the errors and the results.

Returns:

The combined result of all resource items.

Throws:

E - The first error thrown by the handler.

getContainingDirectory

public File getContainingDirectory()

Description copied from interface: IResolvedFileList

Retrieves the directory that contains all the resolved files; and only the resolved files. The directory is empty when no files were found.

Specified by:

getContainingDirectory in interface IResolvedFileList

Returns:

A temporary directory with all the files from the given descriptor. null when IResourceItemResolutionErrorProviding.getErrors() is not null.

getErrors

public Map<EResourceItemResolutionError,List<AFileListResolutionError>> getErrors()

Specified by:

getErrors in interface IResourceItemResolutionErrorProviding

Returns:

All errors that occurred during the resource item's resolution.

getFileList

public IReferencedFileList getFileList()

Specified by:

getFileList in interface IResolvedFileList

Returns:

The file list that was resolved to obtain this result.

getResourceItems

public List<IResolvedResourceItem> getResourceItems()

Description copied from interface: IResolvedFileList

Retrieves the list of resolved resource items. This list always contains one entry for each ResourceItem that was passed to resolveReferencedFiles, whether or not any exceptions occurred while resolving that item. When IResourceItemResolutionErrorProviding.getErrors() is not null, this list is empty.

Specified by:

getResourceItems in interface IResolvedFileList

Returns:

A list with the resolved files.

ofError

public static IResolvedFileList ofError(AFileListResolutionError.CannotProcessFileList error)

Creates a new POJO with the given data and no containing directory and files.

Parameters:

error - Value as returned by getErrors().

Returns:

New resolved file list for the given error.

ofSuccess

public static IResolvedFileList ofSuccess(IReferencedFileList fileList,
 File containingDirectory,
 List<IResolvedResourceItem> resourceItems)

Creates a new POJO with the given data and the getErrors() set to null.

Parameters:

fileList - Original file list that was processed.

containingDirectory - Value as returned by getContainingDirectory().

resourceItems - Value as returned by getResourceItems().

Returns:

New resolved file list for the given resolved items.
