segments

segments_view

A view representing path segments in a URL.

Synopsis

Defined in header <boost/url/segments_view.hpp>

class segments_view :
    public segments_base

Types

Name	Description
const_iterator	A Bidirectional iterator to a path segment.
const_reference	The reference type.
difference_type	A signed integer type used to represent differences.
iterator	A Bidirectional iterator to a path segment.
reference	The reference type.
size_type	An unsigned integer type used to represent size.
value_type	The value type.

Member Functions

Name	Description
back	Return the last segment.
begin	Return an iterator to the beginning.
buffer	Return the referenced character buffer.
empty	Return true if there are no segments.
end	Return an iterator to the end.
front	Return the first segment.
is_absolute	Returns true if this references an absolute path.
operator=	Assignment.
segments_view [constructor]	Constructor.
size	Return the number of segments.

Static Member Functions

Name	Description
max_size	Return the maximum number of characters possible.

Objects of this type are used to interpret the path as a bidirectional view of segment strings. 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.

Example

url_view u( "/path/to/file.txt" );

segments_view ps = u.segments();

assert( ps.buffer().data() == u.buffer().data() );

The strings produced when iterators are dereferenced belong to the iterator and become invalidated when that particular iterator is incremented, decremented, or destroyed. Any percent-escapes in returned strings are decoded first.

Iterator Invalidation

Changes to the underlying character buffer can invalidate iterators which reference it.
