.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This filter provides the ability to store arbitrary data structures into a database column using \s-1YAML\s0. This is very similar to the Jifty::DBI::Filter::Storable filter except that the \s-1YAML\s0 format remains human-readable in the database. You can store virtually any Perl data, scalar, hash, array, or object into the database using this filter.
.PP
In addition, \s-1YAML \s0(at least the storage of scalars, hashes, and arrays) is compatible with data structures written in other languages, so you may store or read data between applications written in different languages.
.SH "METHODS"
.IX Header "METHODS"
.SS "encode"
.IX Subsection "encode"
This method is used to encode the Perl data structure into \s-1YAML\s0 formatted text.
.SS "decode"
.IX Subsection "decode"
This method is used to decode the \s-1YAML\s0 formatted text from the database into the Perl data structure.
.SH "IMPLEMENTATION"
.IX Header "IMPLEMENTATION"
This class will attempt to use YAML::Syck if it is available and then fall back upon \s-1YAML\s0. This has been done because the Syck library is written in C and is considerably faster.
