Field Detail

dwFileAttributes

public int dwFileAttributes

The file attributes of a file. For possible values and their descriptions, see File Attribute Constants. The FILE_ATTRIBUTE_SPARSE_FILE attribute on the file is set if any of the streams of the file have ever been sparse.

ftCreationTime

public WinBase.FILETIME ftCreationTime

A FILETIME structure that specifies when a file or directory was created. If the underlying file system does not support creation time, this member is zero.

ftLastAccessTime

public WinBase.FILETIME ftLastAccessTime

A FILETIME structure. For a file, the structure specifies when the file was last read from, written to, or for executable files, run. For a directory, the structure specifies when the directory is created. If the underlying file system does not support last access time, this member is zero. On the FAT file system, the specified date for both files and directories is correct, but the time of day is always set to midnight.

ftLastWriteTime

public WinBase.FILETIME ftLastWriteTime

A FILETIME structure. For a file, the structure specifies when the file was last written to, truncated, or overwritten, for example, when WriteFile or SetEndOfFile are used. The date and time are not updated when file attributes or security descriptors are changed. For a directory, the structure specifies when the directory is created. If the underlying file system does not support last write time, this member is zero.

nFileSizeHigh

public int nFileSizeHigh

The high-order DWORD value of the file size, in bytes. This value is zero unless the file size is greater than MAXDWORD. The size of the file is equal to (nFileSizeHigh * (MAXDWORD+1)) + nFileSizeLow.

nFileSizeLow

public int nFileSizeLow

The low-order DWORD value of the file size, in bytes.

dwReserved0

public int dwReserved0

If the dwFileAttributes member includes the FILE_ATTRIBUTE_REPARSE_POINT attribute, this member specifies the reparse point tag. Otherwise, this value is undefined and should not be used. For more information see Reparse Point Tags. IO_REPARSE_TAG_CSV (0x80000009) IO_REPARSE_TAG_DEDUP (0x80000013) IO_REPARSE_TAG_DFS (0x8000000A) IO_REPARSE_TAG_DFSR (0x80000012) IO_REPARSE_TAG_HSM (0xC0000004) IO_REPARSE_TAG_HSM2 (0x80000006) IO_REPARSE_TAG_MOUNT_POINT (0xA0000003) IO_REPARSE_TAG_NFS (0x80000014) IO_REPARSE_TAG_SIS (0x80000007) IO_REPARSE_TAG_SYMLINK (0xA000000C) IO_REPARSE_TAG_WIM (0x80000008)

dwReserved1

public int dwReserved1

Reserved for future use.

cFileName

public char[] cFileName

The name of the file. NOTE: When written from Native memory, this will be a null terminated string. Any characters after the null terminator are random memory. Use function getFileName to get a String with the name.

cAlternateFileName

public char[] cAlternateFileName

An alternative name for the file. This name is in the classic 8.3 file name format. NOTE: When written from Native memory, this will be a null terminated string. Any characters after the null terminator are random memory. Use function getAlternateFileName to get a String with the alternate name.

Method Detail

sizeOf

public static int sizeOf()

getFieldOrder

protected List<String> getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.

Overrides:

getFieldOrder in class Structure

Returns:

ordered list of field names

getFileName

public String getFileName()

Returns:

String containing the file name

getAlternateFileName

public String getAlternateFileName()

Returns:

String containing the alternate file name
