cocoa - Where can I find some documentation on NSTextStorage editedMask?

Question

The NSTextStorage documentation mentions the editedMask which according to the docs:

Returns the kinds of edits pending for the receiver

However, I cannot seem to find any bit flags for this mask anywhere (either in the docs or in the NSTextStorage api. Does anyone know where I can find the details of this mask? (I have also search stackoverflow and while I find questions referencing the use of the mask, I still cannot find the bit definition).

我相信它是来自NSTextStorageEditedOptionsenum:NSTextStorageEditedAttributes和/或的值的位掩码NSTextStorageEditedCharacters。
