public Class SftpPosixFileAttributeView

Implements java.nio.file.attribute.FileOwnerAttributeView.getOwner.

Doc from java.nio.file.attribute.FileOwnerAttributeView.getOwner.

Read the file owner.

It is implementation specific if the file owner can be a group.

Returns:UserPrincipal

the file owner

Overrides org.apache.sshd.sftp.client.impl.AbstractSftpFileAttributeView.name.

Implements java.nio.file.attribute.PosixFileAttributeView.name, java.nio.file.attribute.AttributeView.name.

Doc from java.nio.file.attribute.PosixFileAttributeView.name.

Returns the name of the attribute view. Attribute views of this type have the name "posix".

Returns:String

Doc from java.nio.file.attribute.AttributeView.name.

the name of the attribute view

@Override

Implements java.nio.file.attribute.PosixFileAttributeView.readAttributes.

Doc from java.nio.file.attribute.BasicFileAttributeView.readAttributes.

Reads the basic file attributes as a bulk operation.

It is implementation specific if all file attributes are read as an atomic operation with respect to other file system operations.

Returns:PosixFileAttributes

the file attributes

Implements java.nio.file.attribute.PosixFileAttributeView.setGroup.

Doc from java.nio.file.attribute.PosixFileAttributeView.setGroup.

Updates the file group-owner.

Parameters

group:GroupPrincipal

the new file group-owner

Implements java.nio.file.attribute.FileOwnerAttributeView.setOwner.

Doc from java.nio.file.attribute.FileOwnerAttributeView.setOwner.

Updates the file owner.

It is implementation specific if the file owner can be a group. To ensure consistent and correct behavior across platforms it is recommended that this method should only be used to set the file owner to a user principal that is not a group.

Parameters

owner:UserPrincipal

the new file owner

Annotations

@Override

Exceptions

IOException:

if an I/O error occurs, or the owner parameter is a group and this implementation does not support setting the owner to a group

Implements java.nio.file.attribute.PosixFileAttributeView.setPermissions.

Doc from java.nio.file.attribute.PosixFileAttributeView.setPermissions.

Updates the file permissions.

Parameters

perms:Set<PosixFilePermission>

the new set of permissions

Implements java.nio.file.attribute.BasicFileAttributeView.setTimes.

Doc from java.nio.file.attribute.BasicFileAttributeView.setTimes.

Updates any or all of the file's last modified time, last access time, and create time attributes.

This method updates the file's timestamp attributes. The values are converted to the epoch and precision supported by the file system. Converting from finer to coarser granularities results in precision loss. The behavior of this method when attempting to set a timestamp that is not supported or to a value that is outside the range supported by the underlying file store is not defined. It may or not fail by throwing an IOException.

If any of the lastModifiedTime, lastAccessTime, or createTime parameters has the value null then the corresponding timestamp is not changed. An implementation may require to read the existing values of the file attributes when only some, but not all, of the timestamp attributes are updated. Consequently, this method may not be an atomic operation with respect to other file system operations. Reading and re-writing existing values may also result in precision loss. If all of the lastModifiedTime, lastAccessTime and createTime parameters are null then this method has no effect.

Usage Example: Suppose we want to change a file's last access time.

Path path = ...
FileTime time = ...
Files.getFileAttributeView(path, BasicFileAttributeView.class).setTimes(null, time, null);

Parameters

lastModifiedTime:FileTime

the new last modified time, or null to not change the value

lastAccessTime:FileTime

the last access time, or null to not change the value

createTime:FileTime

the file's create time, or null to not change the value
