Interface Tag

All Known Implementing Classes:
NonConvertedTag, StandardTag, UnspecifiedTag
public interface Tag
A Tag is a value that can be easily extracted from images with an external install of ExifTool.
A tag that can be easily parsed to a valid value using the parse(String) hint from each Tag. Using this method allow anyone to convert a string value to the correct data format.
Implementations should not make an attempt at converting the value automatically in case the caller decides they would prefer tag values returned in StandardFormat.HUMAN_READABLE format and to avoid any compatibility issues with future versions of ExifTool if a tag's return value is changed. This approach to leaving returned tag values as strings until the caller decides they want to parse them is a safer and more robust approach.
The types provided by each tag are merely a hint based on the ExifTool Tag Guide by Phil Harvey; the caller is free to parse or process the returned String values any way they wish.
