public final void delete(Path file) throws IOException

Implements abstract java.nio.file.spi.FileSystemProvider.delete.

Doc from java.nio.file.spi.FileSystemProvider.delete.

Deletes a file. This method works in exactly the manner specified by the Files#delete method.

Parameters
file:Path

the path to the file to delete

@Override
Exceptions
IOException:
if an I/O error occurs
deleteIfExistsback to summary
public final boolean deleteIfExists(Path file) throws IOException

Overrides java.nio.file.spi.FileSystemProvider.deleteIfExists.

Doc from java.nio.file.spi.FileSystemProvider.deleteIfExists.

Deletes a file if it exists. This method works in exactly the manner specified by the Files#deleteIfExists method.

The default implementation of this method simply invokes delete ignoring the NoSuchFileException when the file does not exist. It may be overridden where appropriate.

Parameters
file:Path

the path to the file to delete

Returns:boolean

true if the file was deleted by this method; false if the file could not be deleted because it did not exist

Annotations
@Override
Exceptions
IOException:
if an I/O error occurs
getFileAttributeViewback to summary
pack-priv abstract DynamicFileAttributeView getFileAttributeView(Path file, String name, LinkOption... options)

Gets a DynamicFileAttributeView by name. Returns null if the view is not available.

getSunPathForSocketFileback to summary
public abstract byte[] getSunPathForSocketFile(Path path)

Returns a path name as bytes for a Unix domain socket. Different encodings may be used for these names on some platforms. If path is empty, then an empty byte[] is returned.

implDeleteback to summary
pack-priv abstract boolean implDelete(Path file, boolean failIfNotExists) throws IOException

Deletes a file. The failIfNotExists parameters determines if an IOException is thrown when the file does not exist.

isExecutableback to summary
public boolean isExecutable(Path path)

Tests whether a file is executable.

isReadableback to summary
public boolean isReadable(Path path)

Tests whether a file is readable.

isWritableback to summary
public boolean isWritable(Path path)

Tests whether a file is writable.

Parameters
file:Path

the path to the file

attributes:String
