PosixFileAttributes (Java Platform SE 7 )


Quote:
public interface PosixFileAttributes

extends BasicFileAttributes

File attributes associated with files on file systems used by operating systems that implement the Portable Operating System Interface (POSIX) family of standards.
The POSIX attributes of a file are retrieved using a PosixFileAttributeView by invoking its readAttributes method.



Method Summary

Methods

Modifier and Type Method and Description

GroupPrincipal group()

Returns the group owner of the file.

UserPrincipal owner()

Returns the owner of the file.

Set<PosixFilePermission> permissions()

Returns the permissions of the file.

Methods inherited from interface java.nio.file.attribute.BasicFileAttributes

creationTime, fileKey, isDirectory, isOther, isRegularFile, isSymbolicLink, lastAccessTime, lastModifiedTime, size

Method Detail

owner

UserPrincipal owner()

Returns the owner of the file.

Returns:

the file owner

See Also:

FileOwnerAttributeView.setOwner(java.nio.file.attribute.UserPrincipal)

group

GroupPrincipal group()

Returns the group owner of the file.

Returns:
the file group owner

See Also:
PosixFileAttributeView.setGroup(java.nio.file.attribute.GroupPrincipal)

permissions
Set<PosixFilePermission> permissions()

Returns the permissions of the file. The file permissions are returned as a set of PosixFilePermission elements. The returned set is a copy of the file permissions and is modifiable. This allows the result to be modified and passed to the setPermissions method to update the file's permissions.

Returns:
the file permissions

See Also:

PosixFileAttributeView.setPermissions(java.util.Set<java.nio.file.attribute.PosixFilePermission>)

h5perf_serial

H5PERF_SERIAL:(1)						   User Commands						 H5PERF_SERIAL:(1)

NAME

       h5perf_serial: - Measures HDF5 serial performance.

DESCRIPTION

       h5perf_serial: Version 1.8.7 usage: h5perf_serial [OPTIONS]

	      OPTIONS

       -h     Print an usage message and exit

       -A AL  Which APIs to test [default: all of them]

       -c SL  Selects chunked storage and defines chunks dimensions and sizes [default: Off]

       -e SL  Dimensions and sizes of dataset [default: 100,200]

       -i N   Number of iterations to perform [default: 1]

       -r NL  Dimension access order (see below for description) [default: 1,2]

       -t     Selects extendable dimensions for HDF5 dataset [default: Off]

       -v VFD Selects file driver for HDF5 access [default: sec2]

       -w     Perform write tests, not the read tests [default: Off]

       -x SL  Dimensions and sizes of the transfer buffer [default: 10,20]

       N      - is an integer > 0.

       S      - is a size specifier, an integer > 0 followed by a size indicator:

	      K - Kilobyte (1024) M - Megabyte (1048576) G - Gigabyte (1073741824)

	      Example: '37M' is 37 megabytes or 38797312 bytes

	      AL - is an API list. Valid values are:

	      hdf5 - HDF5 posix - POSIX

	      Example: -A posix,hdf5

	      NL - is list of integers (N) separated by commas.

	      Example: 1,2,3

	      SL - is list of size specifiers (S) separated by commas.

	      Example: 2K,2K,3K

	      The  example defines an object (dataset, tranfer buffer) with three dimensions. Be aware that as the number of dimensions increases,
	      the the total size of the object increases exponentially.

       VFD    - is an HDF5 file driver specifier. Valid values are:

	      sec2, stdio, core, split, multi, family, direct

	      Dimension access order:

	      Data access starts at the cardinal origin of the dataset using the transfer buffer. The next access occurs on a dataset region  next
	      to  the  previous one. For a multidimensional dataset, there are several directions as to where to proceed. This can be specified in
	      the dimension access order. For example, -r 1,2 states that the tool should traverse dimension 1 first, and then dimension 2.

	      Environment variables:

       HDF5_NOCLEANUP
	      Do not remove data files if set [default remove]

       HDF5_PREFIX
	      Data file prefix

       usage: h5perf_serial [OPTIONS]
