Method Details

getName

public static String getName(File file)

getFile

@Nonnull
public File getFile()

Returns the resource file.

Specified by:

getFile in interface FileSupplier

Returns:

The file

getContents

@Nonnull
public InputStream getContents()
                        throws IOException

Description copied from interface: PlexusIoResource

Creates an InputStream, which may be used to read the files contents. This is useful, if the file selector comes to a decision based on the files contents.

Please note that this InputStream is unbuffered. Clients should wrap this in a BufferedInputStream or attempt reading reasonably large chunks (8K+).

Specified by:

getContents in interface ContentSupplier

Specified by:

getContents in interface FileInfo

Specified by:

getContents in interface PlexusIoResource

Throws:

IOException

getURL

@Nonnull
public URL getURL()
           throws IOException

Description copied from interface: PlexusIoResource

Returns an URL, which may be used to reference the resource, if possible.

Specified by:

getURL in interface PlexusIoResource

Returns:

An URL referencing the resource, if possible, or null. In the latter case, you are forced to use PlexusIoResource.getContents().

Throws:

IOException

getSize

public long getSize()

Description copied from interface: PlexusIoResource

Returns the resources size, if known. Otherwise returns PlexusIoResource.UNKNOWN_RESOURCE_SIZE.

Specified by:

getSize in interface PlexusIoResource

Specified by:

getSize in interface SizeSupplier

Overrides:

getSize in class AbstractPlexusIoResource

isDirectory

public boolean isDirectory()

Description copied from interface: PlexusIoResource

Returns, whether the FileInfo refers to a directory.

Specified by:

isDirectory in interface FileInfo

Specified by:

isDirectory in interface PlexusIoResource

Overrides:

isDirectory in class AbstractPlexusIoResource

isExisting

public boolean isExisting()

Description copied from interface: PlexusIoResource

Returns, whether the resource exists.

Specified by:

isExisting in interface PlexusIoResource

Overrides:

isExisting in class AbstractPlexusIoResource

isFile

public boolean isFile()

Description copied from interface: PlexusIoResource

Returns, whether the FileInfo refers to a file.

Specified by:

• File.lastModified()

isSymbolicLink

public boolean isSymbolicLink()

Description copied from interface: FileInfo

Returns, whether the FileInfo refers to a symlink. This does not necessarily mean that the underlying representation *is* a symlink on disk, but that this resource represents a symlink. This method will return "false" for java versions prior to java7.

Specified by:

isSymbolicLink in interface FileInfo

Overrides:

isSymbolicLink in class AbstractPlexusIoResource
