Method Details

filetimeToDate

public static Date filetimeToDate(int high,
 int low)

Converts a Windows FILETIME into a Date. The Windows FILETIME structure holds a date and time associated with a file. The structure identifies a 64-bit integer specifying the number of 100-nanosecond intervals which have passed since January 1, 1601. This 64-bit value is split into the two double words stored in the structure.

Parameters:

high - The higher double word of the FILETIME structure.

low - The lower double word of the FILETIME structure.

Returns:

The Windows FILETIME as a Date.

dateToFileTime

public static long dateToFileTime(Date date)

Converts a Date into a filetime.

Parameters:

date - The date to be converted

Returns:

The filetime

See Also:

• filetimeToDate(int, int)

toDate

public Date toDate()

Converts this filetime into a Date

Returns:

The Date represented by this filetime.

toTime

public long toTime()

Converts this filetime into a number of milliseconds which have passed since January 1, 1970 (UTC).

Returns:

This filetime as a number of milliseconds which have passed since January 1, 1970 (UTC)

toDWordLong

public WinDef.DWORDLONG toDWordLong()

Converts the two 32-bit unsigned integer parts of this filetime into a 64-bit unsigned integer representing the number of 100-nanosecond intervals since January 1, 1601 (UTC).

Returns:

This filetime as a 64-bit unsigned integer number of 100-nanosecond intervals since January 1, 1601 (UTC).

toString

public String toString()

Description copied from class: Structure

If jna.dump_memory is true, will include a native memory dump of the Structure's backing memory.

Overrides:

toString in class Structure

Returns:

String representation of this object.
