NAME

Treex::Core::Node::InClause

VERSION

version 0.06571

DESCRIPTION

Moose role for nodes in trees where (linguistic) clauses can be recognized based on attributes clause_number and is_clause_head.

ATTRIBUTES

clause_number

Ordinal number that is shared by all nodes of a same clause.

is_clause_head

Is this node a head of a finite clause.

METHODS

my $clause_head_node = $node->get_clause_root();

Returns the head node of a clause. This implementation is based on the attribute clause_number. Note that it may give different results than get_clause_head.

$clause_head_node = $node->get_clause_head();

Returns the head node of a clause. This implementation is based on the attribute is_clause_head. Note that it may give different results than get_clause_root.

my @nodes = $node->get_clause_descendants();

Returns those descendants which are in the same clause as $node. The current implementation is based on the attribute is_clause_head.

my @nodes = $node->get_clause_nodes();

Returns all nodes of the clause (to which the $node belongs). The current implementation is based on the attribute clause_number.
