Detailed Description

The attribute path evaluator evalues a full attribute path and returns the matching attribute store attribute for that attribute path.

The evaluation is done in the context context.

Constructor & Destructor Documentation

attribute_path_eval()

ast::attribute_path_eval::attribute_path_eval ( const attribute_store::attribute  context )

inlineexplicit

Construct a new attribute path eval object.

Parameters

context

parent on the attribute store

Member Function Documentation

all_elements_parsed()

bool ast::attribute_path_eval::all_elements_parsed ( ) const

inline

Return true if the path has been fully resolved

get_depth()

size_t ast::attribute_path_eval::get_depth

(

const std::vector< attribute_path_element > &

paths

)

const

Return the depth of the path, ie the number ofr path elemnts

last_fail_type()

attribute_store_type_t ast::attribute_path_eval::last_fail_type ( ) const

inline

get the type is of the last element that was attempted to be parsed

last_token_failed()

bool ast::attribute_path_eval::last_token_failed ( ) const

inline

return true if all but the last path elements has been resolved

operator()() [1/5]

attribute_store::attribute ast::attribute_path_eval::operator()

(

const ast::operand &

oper

)
