Treex::PML::Container - content and attributes


This class implements the data type 'container'. A container consists of a central value called content annotated by a set of name-value pairs called attributes whose values are atomic. Treex::PML represents the container class as a subclass of Treex::PML::Struct, where attributes are represented as members and the content as a member with a reserved name '#content'.


Treex::PML::Container->new (value?, { name=>attr, ...}?,reuse?)

Create a new container (optionally initializing its value and attributes). If reuse is true, the hash reference passed may be reused (re-blessed) into the structure.

NOTE: Don't call this constructor directly, use Treex::PML::Factory->createContainer() instead!

$container->attributes ()

Return (assorted) list of names of all attributes.


Return the content value of the container.


This is an alias for value().


Get value of a given attribute. This is just an alias for the inherited Treex::PML::Struct::get_member().

$container->set_attribute($name, $value)

Set value of a given attribute. This is just an alias for the inherited Treex::PML::Struct::set_member().
