Detailed Description

template<typename _DeclT, typename _ImplT = _DeclT>
class xtd::parse::rule< _DeclT, _ImplT >

Curiously recurring template pattern to simplify creation of rule_base implementations Rules and terminals implement the rule_base interface through this pattern.

It provides boiler plate pointer_type, isa() and type() members.

Template Parameters

_DeclT	The type declaration. Permits access to the implementation from the rule class template. Declaration pass their name in the form of: class SomeRule : rule<SomeRule>
_ImplT	The declaration used by the parsing algorithms. The library instantiates type of _DeclT when _ImplT successfully parses.

Member Function Documentation

template<typename _DeclT, typename _ImplT = _DeclT>

virtual bool xtd::parse::rule< _DeclT, _ImplT >::isa ( const std::type_info &  oType ) const

inlineoverridevirtual

Determines if the interface is implemented by a concrete type.

Parameters

[in]

oType

type to test

Returns

true if the implementation's is the specified type
