Detailed Description

Run-time type information (RTTI) container class.

This utility class implementation is done primarily to help encapsulate implementation details that are subject to availability – not all platforms support RTTI (typeid, std::type_index), nor are the supported platforms implemented the same (i.e.: name strings).

See also: nom::IObject.

Constructor & Destructor Documentation

ObjectTypeInfo()

nom::ObjectTypeInfo::ObjectTypeInfo

(

const value_type &

object

)

Constructor for a complete object initialization.

Parameters

std::type_info

object; pass through the typeid method.

Member Function Documentation

hash_code()

size_t nom::ObjectTypeInfo::hash_code

(

void

)

const

Get the object's type hash code.

Returns

A hash code value that identifies the type.

Remarks

This function returns the same value for any two type_info objects that compare equal.

Note

The particular values returned are implementation-defined and may vary between executions of the same program.

name()

const std::string nom::ObjectTypeInfo::name

(

void

)

const

Get the object type's name.

Returns

A null-terminated character sequence that may identify the object's type.

Note

The particular representation pointed by the returned value is implementation-defined, and may or may not be different for different types.

operator==()

bool nom::ObjectTypeInfo::operator==

(

const self_type &

rhs

)

const

Equality comparison operator.

Remarks

This operator overload is provided so that we are able to conveniently compare two nom::ObjectTypeInfo objects with minimal effort – note that we could not have ::type declared under private scope if not for this provision.
