Detailed Description

Represents the parse tree for a sentence.

This may either be a sentence parsed from training data, or the output from a trained parser on test data.

Todo:

determine what parts of analyzers::parse_tree are worth keeping—that class deals specifically with trees read from the output of the Stanford parser. When we have our own, we may still want some of that functionality to allow people to use parsers that are not our own?

Constructor & Destructor Documentation

meta::parser::parse_tree::parse_tree

(

std::unique_ptr< node >

root

)

Creates a new parse tree by taking ownership of a subtree pointed to by the argument.

Parameters

root	The desired root of the parse tree

Member Function Documentation

template<class Visitor >

std::remove_reference<Visitor>::type::result_type meta::parser::parse_tree::visit ( Visitor &&  vtor )

inline

Runs a visitor over the parse tree.

Non-const version.

Returns

the result from the visitor.

template<class Visitor >

std::remove_reference<Visitor>::type::result_type meta::parser::parse_tree::visit ( Visitor &&  vtor ) const

inline

Runs a visitor over the parse tree.

Const version.

Returns

the result from the visitor.

void meta::parser::parse_tree::pretty_print

(

std::ostream &

os

)

const

Prints a parse tree to a stream.

This is indented.

Parameters

os	The stream to print to

Friends And Related Function Documentation

std::ostream& operator<< ( std::ostream &  os, const parse_tree &  tree  )

friend

Prints a parse tree to a stream.

This is non-indented.

Parameters

os	The stream to print to
tree	The tree to be printed

Returns

the stream

bool operator== ( const parse_tree &  lhs, const parse_tree &  rhs  )

friend

Parameters

lhs	The left hand side of the expression
rhs	The right hand side of the expression

Returns

whether the two parse trees are equivalent
