Config::Model::Dumper(3pm) User Contributed Perl Documentation Config::Model::Dumper(3pm)NAME
Config::Model::Dumper - Serialize data of config tree
VERSION
version 2.021
SYNOPSIS
use Config::Model ;
use Log::Log4perl qw(:easy) ;
Log::Log4perl->easy_init($WARN);
# define configuration tree object
my $model = Config::Model->new ;
$model ->create_config_class (
name => "MyClass",
element => [
[qw/foo bar/] => {
type => 'leaf',
value_type => 'string'
},
baz => {
type => 'hash',
index_type => 'string' ,
cargo => {
type => 'leaf',
value_type => 'string',
},
},
],
) ;
my $inst = $model->instance(root_class_name => 'MyClass' );
my $root = $inst->config_root ;
# put some data in config tree the hard way
$root->fetch_element('foo')->store('yada') ;
$root->fetch_element('bar')->store('bla bla') ;
$root->fetch_element('baz')->fetch_with_id('en')->store('hello') ;
# put more data the easy way
my $step = 'baz:fr=bonjour baz:hr="dobar dan"';
$root->load( step => $step ) ;
# dump only customized data
print $root->dump_tree;
DESCRIPTION
This module is used directly by Config::Model::Node to serialize configuration data in a compact (but readable) string.
The serialization can be done in standard mode where only customized values are dumped in the string. I.e. only data modified by the user
are dumped.
The other mode is "full_dump" mode where all all data, including default values, are dumped.
The serialized string can be used by Config::Model::Walker to store the data back into a configuration tree.
Note that undefined values are skipped for list element. I.e. if a list element contains "('a',undef,'b')", the dump will contain 'a','b'.
CONSTRUCTOR
new ( )
No parameter. The constructor should be used only by Config::Model::Node.
Methods
dump_tree
Return a string that contains a dump of the object tree with all the values. This string follows the convention defined by
Config::Model::Walker.
The serialized string can be used by Config::Model::Walker to store the data back into a configuration tree.
Parameters are:
mode ( full | preset | custom )
"full" will dump all configuration data including default values.
"preset" will dump only value entered in preset mode.
By default, the dump contains only data modified by the user (i.e. "custom" data that differ from default or preset values).
node
Reference to the Config::Model::Node object that is dumped. All nodes and leaves attached to this node are also dumped.
skip_auto_write ( <backend_name> )
Skip node that have a write capability matching "backend_name" in their model. See Config::Model::AutoRead.
auto_vivify
Scan and create data for nodes elements even if no actual data was stored in them. This may be useful to trap missing mandatory values.
(default: 0)
experience ( ... )
Restrict dump to "beginner" or "intermediate" parameters. Default is to dump all parameters ("master" level)
check
Check value before dumping. Valid check are 'yes', 'no' and 'skip'.
