Text::Snippet::TabStop::Cursor - Provides a bi-directional iterator interface for moving from one tab-stop to it's siblings
version 0.04
snippet
Maintains a reference to the snippet that this cursor is iterating over.
has_prev
Returns true/false depending on whether the cursor can move to a previous tab stop.
prev
Moves the cursor to the previous tab stop and returns that tab stop. You can only iterate one element off the end of the underlying set of tab stops.
has_next
Returns true/false depending on whether the cursor can move to a subsequent tab stop.
next
Moves the cursor to the next tab stop and returns that tab stop. You can only iterate one element off the end of the underlying set of tab stops.
current
Returns the tab stop the cursor is currently pointing at. When the cursor is first created, this method will always return undef until next has been called at least once.
undef
current_position
Returns an ArrayRef reflecting the line/column position relative to the beginning of the snippet. Both numbers are zero-based so a tab stop starting on the first line, first character would return a value of [0,0].
[0,0]
current_char_position
Returns an integer reflecting the current cursor position where 0 is the first character of the snippet and each character is counted up until the current position of the cursor.
is_terminal
Returns true if this tab stop is a "terminal" tab stop (i.e. once the user iterates to this tab stop, the iterator should be restored and normal editing should resume).
