Detailed Description

template<typename TValue>
class TypeObjectsMap< TValue >

This utility class is a dictionary, used to store anonymous object by a key.

This class designed to store objects of anonymous type with unique keys. It is used in service locators and component extensions.

Member Function Documentation

template<typename TValue >

TValue TypeObjectsMap< TValue >::getInstance

(

const QString &

key

)

const

Finds pointer associated with specified key and empty tag in inner objects dictionary.

Returns

The value corresponded with specified key if such found. Null pointer otherwise.

template<typename TValue >

TValue TypeObjectsMap< TValue >::getInstance	(	const QString &	key,
		const QString &	tag
	)		const

Finds pointer associated with specified key and tag in inner objects dictionary.

Returns

The value corresponded with specified key if such found. Null pointer otherwise.

template<typename TValue>

void TypeObjectsMap< TValue >::registerInstance	(	TValue	instance,
		const QString &	key
	)

Registers a value with empty tag and specified key in inner objects dictionary.

template<typename TValue>

void TypeObjectsMap< TValue >::registerInstance	(	TValue	instance,
		const QString &	key,
		const QString &	tag
	)

Registers a value with specified key and tag in inner objects dictionary.

template<typename TValue >

int TypeObjectsMap< TValue >::size

(

)

const

Returns the amount of registered in map objects.

template<typename TValue >

TValue TypeObjectsMap< TValue >::unregisterInstance	(	const QString &	key,
		const QString &	tag
	)

Removes value with specified key and tag from the inner objects dictionary.

Returns

The raw pointer corresponded with specified key and tag if such found. Default value TValue() otherwise.

template<typename TValue >

QStringList TypeObjectsMap< TValue >::keys

(

)

const

Returns all registered keys for instances;

template<typename TValue >

QStringList TypeObjectsMap< TValue >::keys

(

const QString &

tag

)

const
