NAME
Treex::PML::Alt - an alternative of uniformly typed PML values
DESCRIPTION
This class implements the attribute value type 'alternative'.
- Treex::PML::Alt->new (value1,value2,...)
-
Create a new alternative (optionally populated with given values).
NOTE: Don't call this constructor directly, use Treex::PML::Factory->createAlt() instead!
- Treex::PML::Alt->new_from_ref (array_ref, reuse)
-
Create a new alternative consisting of values in a given array reference. If reuse is true, then the same array_ref scalar is reused to represent the Treex::PML::Alt object (i.e. blessed). Otherwise, a copy is created in the constructor.
NOTE: Don't call this constructor directly, use Treex::PML::Factory->createAlt() instead!
- $alt->values ()

- $alt->count ()
