Detailed Description

Objects of class Type are used to maintain information about reflected types. They also provide a number of services, like instance creation and dynamic calling of methods. All details about the data type being described are available at runtime, provided that the type was defined (and not just declared) through a Reflector class. It is not possible to modify a Type object once it has been created, unless you are a class derived from Reflector (which has firm friendship with this class).

const [inline]

Value osgIntrospection::Type::createInstance

(

ValueList &

args

)

const

Creates an instance of the reflected type. The returned Value can be casted to T*, where T is the reflected type. If the type is abstract, an exception is thrown.

int

i

)

const [inline]

Returns the i-th name alias.

void osgIntrospection::Type::getAllMethods

(

MethodInfoList &

methods

)

const

Fills a list of methods that are either defined in this Type or in inherited types.

void osgIntrospection::Type::getAllProperties

(

PropertyInfoList &

props

)

const

Fills a list of properties that are either defined in this Type or in inherited types.

const Type & osgIntrospection::Type::getBaseType

(

int

i

)

const [inline]

Returns the i-th base type.

const TypeList & osgIntrospection::Type::getBaseTypeList

(

)

const [inline]

Returns the base type list.

const Comparator * osgIntrospection::Type::getComparator

(

)

const [inline]

Returns the instance of the comparator object assigned to this type, if any. Otherwise it returns the null pointer.

const ConstructorInfo* osgIntrospection::Type::getCompatibleConstructor

(

const ValueList &

values

)

const

Searches for a constructor that can be called with the given list of arguments without raising type conversion errors. If more than one constructors are suitable for calling, the best match is returned.

const MethodInfo* osgIntrospection::Type::getCompatibleMethod	(	const std::string &	name,
		const ValueList &	values,
		bool	inherit
	)			const

Searches for a method that can be called with the given list of arguments without raising type conversion errors. If more than one method are suitable for calling, the best match is returned.

const ConstructorInfo* osgIntrospection::Type::getConstructor

(

const ParameterInfoList &

params

)

const

Searches for a constructor whose parameters match exactly the given list of parameter descriptions.

const ConstructorInfoList & osgIntrospection::Type::getConstructors

(

)

const [inline]

Returns the list of constructors defined for this type.

const EnumLabelMap & osgIntrospection::Type::getEnumLabels

(

)

const [inline]

Returns the map of enumeration labels. If the type is not an enumeration, an empty map is returned.

virtual void osgIntrospection::Type::getInheritedProviders

(

CustomAttributeProviderList &

providers

)

const [protected, virtual]

Implements osgIntrospection::CustomAttributeProvider.

const MethodInfo* osgIntrospection::Type::getMethod	(	const std::string &	name,
		const ParameterInfoList &	params,
		bool	inherit
	)			const

Searches for a method whose parameters match exactly the given list of parameter descriptions.

const MethodInfoList & osgIntrospection::Type::getMethods

(

)

const [inline]

Returns the list of methods defined for this type. The list does not include methods inherited from base types.

void osgIntrospection::Type::getMethodsMap

(

MethodInfoMap &

methods

)

const

Fills a map of "type <-> MethodInfoList" that are either defined in this Type or in inherited types.

const std::string & osgIntrospection::Type::getName

(

)

const [inline]

Returns the name of the reflected type.

const std::string & osgIntrospection::Type::getNamespace

(

)

const [inline]

Returns the namespace of the reflected type.

int osgIntrospection::Type::getNumAliases

(

)

const [inline]

Returns the number of type name aliases.

int osgIntrospection::Type::getNumBaseTypes

(

)

const [inline]

Returns the number of base types. This number is zero if the type is not derived from any other type.

const Type & osgIntrospection::Type::getPointedType

(

)

const [inline]

Returns the pointed type. If the reflected type is not a pointer, the object returned is typeof(void).

const PropertyInfoList & osgIntrospection::Type::getProperties

		bool	inherit
	)			const

Searches for a property given its name, type and list of indices. Only exact matches are returned.

std::string osgIntrospection::Type::getQualifiedName

(

)

const [inline]

Returns the qualified name of the reflected type. The qualified name is formed by the namespace, if present, plus other modifiers like 'const' and/or '*' (pointer) where applicable.

const ReaderWriter * osgIntrospection::Type::getReaderWriter

(

)

const [inline]

Returns the instance of the reader/writer object assigned to this type, if any. Otherwise it returns the null pointer.

const std::type_info & osgIntrospection::Type::getStdTypeInfo

(

)

const [inline]
