Detailed Description

A single node in a parse tree for a sentence.

Constructor & Destructor Documentation

meta::parser::node::node

(

class_label

cat

)

Constructs a new node with the given category.

Parameters

cat	The category for the new node

Member Function Documentation

const class_label & meta::parser::node::category

(

)

const

Returns

the category for the node

bool meta::parser::node::is_leaf ( ) const

pure virtual

Returns

whether this node is a leaf node

bool meta::parser::node::is_temporary

(

)

const

Returns

whether this node is a temporary node inserted during binarization

virtual bool meta::parser::node::equal ( const node &  other ) const

pure virtual

Parameters

other

The other subtree to compare with

Returns

whether this subtree is equal to the other subtree

virtual std::unique_ptr<node> meta::parser::node::clone ( ) const

pure virtual

Clones the given node.

Returns

a unique_ptr to a copy of this object

template<class Visitor >

std::remove_reference<Visitor>::type::result_type meta::parser::node::accept ( Visitor &&  vtor )

inline

Accepts a visitor.

Parameters

vtor	The visitor to visit each of the nodes in this subtree

Returns

the visitor result for this subtree

template<class Visitor >

std::remove_reference<Visitor>::type::result_type meta::parser::node::accept ( Visitor &&  vtor ) const

inline

Accepts a visitor (const version).

Can only accept visitors that do not modify the tree directly.

Parameters

vtor	The visitor to visit each of the nodes in this subtree

Returns

the visitor result for this subtree

template<class Node >

Node& meta::parser::node::as ( )

inline

Casting operation for nodes to derived types.

Node can only be a parser::leaf_node or parser::internal_node, and must be consistent with is_leaf().

Returns

this node cast to the given node type

template<class Node >

std::add_const<Node>::type& meta::parser::node::as ( ) const

inline

Casting operation for nodes to derived types.

Node can only be a parser::leaf_node or parser::internal_node, and must be consistent with is_leaf().

Returns

this node cast to the given node type
