NAME
"String::Tagged::Extent" - represents a range within a "String::Tagged"
DESCRIPTION
These objects represent a range of characters within the containing String::Tagged object. The range they represent is fixed at the time of creation. If the containing string is modified by a call to "set_substr" then the effect on the extent object is not defined. These objects should be considered as relatively short-lived - used briefly for the purpose of querying the result of an operation, then discarded soon after.
METHODS
string $extent->string Returns the containing String::Tagged object. start $extent->start Returns the start index of the extent. This is the index of the first character within the extent. end $extent->end Returns the end index of the extent. This is the index of the first character beyond the end of the extent. anchor_before $extent->anchor_before True if this extent begins "before" the start of the string. Only certain methods return extents with this flag defined. anchor_after $extent->anchor_after True if this extent ends "after" the end of the string. Only certain methods return extents with this flag defined. length $extent->length Returns the number of characters within the extent. substr $extent->substr Returns the substring contained by the extent, as a String::Tagged complete with all the relevant tag values. plain_substr $extent->plain_substr Returns the substring of the underlying plain string buffer contained by the extent, as a plain Perl string.
