Description
Objects of this type are used to interpret the path as a bidirectional view of segments, where each segment is a string which may contain percent-escapes. The view does not retain ownership of the elements and instead references the original character buffer. The caller is responsible for ensuring that the lifetime of the buffer extends until it is no longer referenced. The view is modifiable; calling non-const members causes changes to the referenced url.
Example
url u( "/path/to/file.txt" );
segments_encoded_ref ps = u.encoded_segments();The strings returned when iterators are dereferenced have type pct_string_view and may contain percent-escapes. Reserved characters in inputs are automatically escaped. Escapes in inputs are preserved. Exceptions are thrown on invalid inputs.
Iterator Invalidation
Changes to the underlying character buffer can invalidate iterators which reference it. Modifications made through the container invalidate some or all iterators:
-
push_back : Only
end(). -
assign, clear, ../../reference/boost/urls/segments_encoded_ref/operator_assign-02c.adoc : All elements.
-
erase : Erased elements and all elements after (including
end()). -
insert : All elements at or after the insertion point (including
end()). -
replace : Modified elements and all elements after (including
end()).
