Method Details

getName

public String getName()

Description copied from class: Directory

Provides the name of the directory, for display purposes. E.g. Exif

Specified by:

getName in class Directory

Returns:

the name of the directory

getDateModified

public Date getDateModified()

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was modified. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the GMT TimeZone.

Returns:

A Date object representing when this image was modified, if possible, otherwise null

getDateModified

public Date getDateModified(TimeZone timeZone)

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was modified. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the TimeZone represented by the timeZone parameter (if it is non-null).

Parameters:

timeZone - the time zone to use

Returns:

A Date object representing when this image was modified, if possible, otherwise null

getDateOriginal

public Date getDateOriginal()

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was captured. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the GMT TimeZone.

Returns:

A Date object representing when this image was captured, if possible, otherwise null

getDateOriginal

public Date getDateOriginal(TimeZone timeZone)

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was captured. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the TimeZone represented by the timeZone parameter (if it is non-null).

Parameters:

timeZone - the time zone to use

Returns:

A Date object representing when this image was captured, if possible, otherwise null

getDateDigitized

public Date getDateDigitized()

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was digitized. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the GMT TimeZone.

Returns:

A Date object representing when this image was digitized, if possible, otherwise null

getDateDigitized

public Date getDateDigitized(TimeZone timeZone)

Parses the date/time tag, the subsecond tag and the time offset tag to obtain a single Date object with milliseconds representing the date and time when this image was digitized. If the time offset tag does not exist, attempts will be made to parse the values as though it is in the TimeZone represented by the timeZone parameter (if it is non-null).

Parameters:

timeZone - the time zone to use

Returns:

A Date object representing when this image was digitized, if possible, otherwise null
