Config::Objective::DataType - base class for Config::Objective data types
use Config::Objective;
use Config::Objective::DataType;
my $conf = Config::Objective->new('filename', {
'objname' => Config::Objective::DataType->new(
'attr1' => 0,
'attr2' => "string",
...
)
});
The Config::Objective::DataType module provides a class that encapsulates
a value in an object so that it can be used with Config::Objective. Its
methods can be used to manipulate the encapsulated value from the config file.
The Config::Objective::DataType class is not intended to be
used to directly instantiate configuration objects, but it does support the
following methods for use in subclasses:
- new()
- The constructor. It can be passed a hash to set the object's attributes.
The object will be created as a reference to this hash.
The value encapsulated by the object is stored in the
"value" attribute. Setting this attribute in the constructor
call will set the initial value for the object. If no initial value is
supplied, the constructor will call the undef() method.
The Config::Objective::DataType class does not use any
other attributes. However, they can be useful in subclasses.
- set()
- Sets the object's value to the supplied value.
- get()
- Returns the object's value.
- unset()
- Sets the object's value to undef.
- default()
- Calls the set() method.
