Method Details

readSymLinkAbsolute

public static Path readSymLinkAbsolute(Path symLink)
                                throws IOException

Read a symbolic link and return and absolute path to its target.

Parameters:

symLink -

Returns:

Throws:

IOException

resolveSymLinkAbsolute

public static Path resolveSymLinkAbsolute(Path symLinkSrc,
 Path symLinkTgt)

Given a path that is considered a symlink and its target, return the absolute path obtained by resolving the target (which may be a relative path) against the symlink. This method allows resolving a relative symlinkTgt of a different file system (e.g. UNIX) against a symLinkSrc (e.g. WebDAV)

Parameters:

symLinkSrc -

symLinkTgt -

Returns:

allocateSymbolicLink

public static Collection<Path> allocateSymbolicLink(SymbolicLinkStrategy symlinkStrategy,
 Path rawTarget,
 Path rawSourceFolder,
 Function<String,String> fileNameNormalizer,
 String prefix,
 String suffix)
                                             throws Exception

Within 'folder' create a link to 'file' with name 'baseName' if it does not yet exist. Return the new link or all prior existing link(s)

Parameters:

file -

folder -

baseName -

Returns:

Throws:

IOException

Exception

allocateSymbolicLink

public static Collection<Path> allocateSymbolicLink(SymbolicLinkStrategy symlinkStrategy,
 Path rawTarget,
 Path rawSourceFolder,
 Function<String,String> fileNameNormalizer,
 String prefix,
 String suffix,
 ThrowingBiFunction<Path,Path,Path> tgtAndContentToFile)
                                             throws Exception

Throws:

Exception

streamSymbolicLinks

public static Function<Stream<Path>,Stream<com.google.common.collect.Table.Cell<String,Path,Path>>> streamSymbolicLinks(SymbolicLinkStrategy symlinkStrategy,
 Function<String,String> fileNameHarmonizer,
 String prefix,
 String suffix)
                                                                                                                 throws IOException

Throws:

IOException

readSymbolicLinks

public static com.google.common.collect.Table<String,Path,Path> readSymbolicLinks(SymbolicLinkStrategy symlinkStrategy,
 Path sourceFolder,
 Function<String,String> filenameNormalizer,
 String prefix,
 String suffix)
                                                                           throws IOException

Within 'sourceFolder' read all symbolic links with the pattern 'baseName${number}' and return a map with their targets.

Parameters:

rawSourceFolder -

baseName -

Returns:

Throws:

IOException
