Config::MVP::Section(3User Contributed Perl DocumentatiConfig::MVP::Section(3)NAMEConfig::MVP::Section - one section of an MVP configuration sequence
VERSION
version 2.200002
DESCRIPTION
For the most part, you can just consult Config::MVP to understand what
this class is and how it's used.
ATTRIBUTES
name
This is the section's name. It's a string, and it must be provided.
package
This is the (Perl) package with which the section is associated. It is
optional. When the section is instantiated, it will ensure that this
package is loaded.
multivalue_args
This attribute is an arrayref of value names that should be considered
multivalue properties in the section. When added to the section, they
will always be wrapped in an arrayref, and they may be added to the
section more than once.
If this attribute is not given during construction, it will default to
the result of calling section's package's "mvp_multivalue_args" method.
If the section has no associated package or if the package doesn't
provide that method, it default to an empty arrayref.
aliases
This attribute is a hashref of name remappings. For example, if it
contains this hashref:
{
file => 'files',
path => 'files',
}
Then attempting to set either the "file" or "path" setting for the
section would actually set the "files" setting.
If this attribute is not given during construction, it will default to
the result of calling section's package's "mvp_aliases" method. If the
section has no associated package or if the package doesn't provide
that method, it default to an empty hashref.
payload
This is the storage into which properties are set. It is a hashref of
names and values. You should probably not alter the contents of the
payload, and should read its contents only.
is_finalized
This attribute is true if the section has been marked finalized, which
will prevent any new values from being added to it. It can be set with
the "finalize" method.
sequence
This attributes points to the sequence into which the section has been
assembled. It may be unset if the section has been created but not yet
placed in a sequence.
METHODS
add_value
$section->add_value( $name => $value );
This method sets the value for the named property to the given value.
If the property is a multivalue property, the new value will be pushed
onto the end of an arrayref that will store all values for that
property.
Attempting to add a value for a non-multivalue property whose value was
already added will result in an exception.
load_package
$section->load_package($package, $plugin);
This method is used to ensure that the given $package is loaded, and is
called whenever a section with a package is created. By default, it
delegates to Class::Load. If the package can't be found, it calls the
missing_package method. Errors in compilation are not suppressed.
missing_package
$section->missing_package($package, $plugin);
This method is called when "load_package" encounters a package that is
not installed. By default, it throws an exception.
