.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
Encodes a scalar, hash reference or array reference as \s-1YAML\s0.
.PP
In the spirit of YAML::Tiny this is a lightweight, dependency-free
\&\s-1YAML\s0 writer. While \f(CW\*(C`YAML::Tiny\*(C'\fR is designed principally for working
with configuration files \f(CW\*(C`Data::YAML\*(C'\fR concentrates on the transparent
round-tripping of \s-1YAML\s0 serialized Perl data structures.
.PP
The syntax produced by \f(CW\*(C`Data::YAML::Writer\*(C'\fR is a subset of \s-1YAML\s0.
Specifically it is the same subset of \s-1YAML\s0 that Data::YAML::Reader
consumes. See Data::YAML for more information.
.SH "INTERFACE"
.IX Header "INTERFACE"
.ie n .IP """new""" 4

.IX Item "new"
The constructor \f(CW\*(C`new\*(C'\fR creates and returns an empty \f(CW\*(C`Data::YAML::Writer\*(C'\fR object.
.ie n .IP """write( $obj, $output )""" 4
.el .IP "\f(CWwrite( $obj, $output )\fR" 4
