.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module provides the \f(CW\*(C`URI::WithBase\*(C'\fR class.  Objects of this class
are like \f(CW\*(C`URI\*(C'\fR objects, but can keep their base too.  The base
represents the context where this URI was found and can be used to
absolutize or relativize the URI.  All the methods described in URI
are supported for \f(CW\*(C`URI::WithBase\*(C'\fR objects.
.PP
The methods provided in addition to or modified from those of \f(CW\*(C`URI\*(C'\fR are:
.ie n .IP "$uri = URI::WithBase\->new($str, [$base])" 4
.el .IP "\f(CW$uri\fR = URI::WithBase\->new($str, [$base])" 4
.IX Item "$uri = URI::WithBase->new($str, [$base])"
The constructor takes an optional base URI as the second argument.
If provided, this argument initializes the base attribute.
.ie n .IP "$uri\->base( [$new_base] )" 4
.el .IP "\f(CW$uri\fR\->base( [$new_base] )" 4
.IX Item "$uri->base( [$new_base] )"
Can be used to get or set the value of the base attribute.
The return value, which is the old value, is a URI object or \f(CW\*(C`undef\*(C'\fR.
.ie n .IP "$uri\->abs( [$base_uri] )" 4
.el .IP "\f(CW$uri\fR\->abs( [$base_uri] )" 4
.IX Item "$uri->abs( [$base_uri] )"
The \f(CW$base_uri\fR argument is now made optional as the object carries its
base with it.  A new object is returned even if \f(CW$uri\fR is already
absolute (while plain URI objects simply return themselves in
that case).
.ie n .IP "$uri\->rel( [$base_uri] )" 4
.el .IP "\f(CW$uri\fR\->rel( [$base_uri] )" 4
.IX Item "$uri->rel( [$base_uri] )"
The \f(CW$base_uri\fR argument is now made optional as the object carries its
base with it.  A new object is always returned.
