| Summary : string buffers with value tags on extents
|
Description :
This module implements an object class, instances of which store a
(mutable) string buffer that supports tags. A tag is a name/value pair that
applies to some extent of the underlying string.
The types of tag names ought to be strings, or at least values that are
well-behaved as strings, as the names will often be used as the keys in
hashes or applied to the \'eq\' operator.
The types of tag values are not restricted - any scalar will do. This could
be a simple integer or string, ARRAY or HASH reference, or even a CODE
reference containing an event handler of some kind.
Tags may be arbitrarily overlapped. Any given offset within the string has
in effect, a set of uniquely named tags. Tags of different names are
independent. For tags of the same name, only the latest, shortest tag takes
effect.
For example, consider a string with three tags represented here:
Here is my string with tags
[-------------------------] foo => 1
[-------] foo => 2
[---] bar => 3
Every character in this string has a tag named \'foo\'. The value of this tag
is 2 for the words \'my\' and \'string\' and the space inbetween, and 1
elsewhere. Additionally, the words \'is\' and \'my\' and the space between them
also have the tag \'bar\' with a value 3.
Since \'String::Tagged\' does not understand the significance of the tag
values it therefore cannot detect if two neighbouring tags really contain
the same semantic idea. Consider the following string:
A string with words
[-------] type => \"message\"
[--------] type => \"message\"
This string contains two tags. \'String::Tagged\' will treat this as two
different tag values as far as \'iter_tags_nooverlap\' is concerned, even
though \'get_tag_at\' yields the same value for the \'type\' tag at any
position in the string. The \'merge_tags\' method may be used to merge tag
extents of tags that should be considered as equal.
