Detailed Description

A resource dictionary is a container that maps resource IDs to resources.

A node can refer to resources by setting resource IDs to resource ID properties. You can set a resource dictionary to the node or to any of its parent nodes to define which resources the node will use. You can use resource dictionary to group similar resources to logical entities like themes or locales, and change a resource dictionary of a node to change multiple resources at the same time.

You can use Node::acquireResource to get the resource from the resource dictionary of a node or from the resource dictionaries of its parent nodes.

A resource dictionary can map resource IDs to resources in these ways: 1) Resource ID can map directly to a resource pointer. 2) Resource ID can map indirectly to a resource with a resource URL. Use acquire and tryAcquire functions to get a mapped resource regardless of the way how a resource ID is mapped to a resource.

You can store nested resource dictionaries in a resource dictionary. When you are getting a resource from a resource dictionary and the resource dictionary cannot find the resource ID you specify, the resource dictionary looks for the resource ID recursively in the nested resource dictionaries.

In a resource dictionary you can store resources without mapping a resource ID to them. In Kanzi Engine such resources are called anonymous resources. You can get anonymous resources with beginAnonymousResources and endAnonymousResources.

Examples

To create a resource dictionary:

// Create a resource dictionary.

ResourceDictionarySharedPtr dictionary = ResourceDictionary::create(domain, "Dictionary");

To add content to a resource dictionary:

        // Add resources to a resource dictionary.
        dictionary->add(ResourceID("red icon"), texture);
        dictionary->add(ResourceID("blue icon"), "kzb://my_project/Textures/Blue Icon");

To get resources from a resource dictionary:

        // Acquire resources from a resource dictionary.
        ResourceSharedPtr redIcon = dictionary->acquire(ResourceID("red icon"));
        ResourceSharedPtr blueIcon = dictionary->acquire(ResourceID("blue icon"));

To change the resource dictionary of a node:

// Change the resource dictionary of a node.

node->setResourceDictionary(dictionary);

To extend the existing resource dictionary of a node:

// Extend the existing resource dictionary of a node with a nested resource dictionary.

node->addResourceDictionary(dictionary);

resource The anonymous resource you want to remove from the resource dictionary. If the resource does not exist in the resource dictionary, the function does not do anything.

void kanzi::ResourceDictionary::add ( ResourceDictionarySharedPtr resourceDictionary )

Adds a nested resource dictionary to the resource dictionary.

Since only a pointer to the nested resource dictionary is stored, the same resource dictionary can be added as a nested resource dictionary to multiple dictionaries. Note that it is forbidden to form cycles with the nested resource dictionaries.

Parameters

resourceDictionary The nested resource dictionary you want to add to the resource dictionary.

size_t kanzi::ResourceDictionary::getDictionaryCount ( ) const

Gets the number of nested resource dictionaries in the resource dictionary.

Returns: The number of nested resource dictionaries in the resource dictionary.

Returns: A reverse iterator to the element following the last element of the reversed nested resource dictionary container.

ResourceDictionarySharedPtr kanzi::ResourceDictionary::findDictionary ( string_view name ) const

Searches for a nested dictionary with the specified name and returns a pointer to it.

Parameters

name	The name of the dictionary to find.

Returns: A child dictionary with the specified name, null otherwise.

ResourceSharedPtr kanzi::ResourceDictionary::findStoredResource ( const ResourceID & key ) const

Find explicitly stored resource pointer from the dictionary.

Does not try to acquire from resource manager, use acquire() if necessary.

ResourceSharedPtr kanzi::ResourceDictionary::acquire ( const ResourceID & key ) const

Gets from the resource dictionary the resource with the resource ID you pass to the function.

Any resource URL mappings are forwarded to ResourceManager::acquireResource. Classes that derive from ResourceDictionary can override the behavior of acquire by implementing acquireOverride.

Parameters

key	The resource ID of the resource you want to get.

Returns

The resource to which the resource ID is mapped.

If the resource ID is mapped to a resource pointer, the function returns the resource pointer.
If the resource ID is mapped to a resource URL, the function uses the URL to query the resource from ResourceManager::acquireResource.
If the resource dictionary has nested resource dictionaries, the function forwards the query to the nested dictionaries: the last nested resource dictionary is searched first, and the first nested resource dictionary is searched last.
If the resource ID is not mapped to anything in this resource dictionary or any of the nested dictionaries, the function returns nullptr.

template<typename Type >

shared_ptr<Type> kanzi::ResourceDictionary::acquire ( const ResourceID & key ) const

inline

Gets from the resource dictionary the resource with the resource ID you pass to the function and casts the resource to the type you specify.

See also: acquire

ResourceSharedPtr kanzi::ResourceDictionary::tryAcquire ( const ResourceID & key ) const

Gets from the resource dictionary the resource with the resource ID you pass to the function.

Any resource URL mappings are forwarded to ResourceManager::tryAcquireResource. Classes that derive from ResourceDictionary can override the behavior of tryAcquire by implementing tryAcquireOverride.

Parameters

key	The resource ID of the resource you want to get.

Returns

The resource to which the resource ID is mapped.

If the resource ID is mapped to a resource pointer, the function returns the resource pointer.
If the resource ID is mapped to a resource URL, the function uses the URL to query the resource from ResourceManager::tryAcquireResource.
If the resource dictionary has nested resource dictionaries, the function forwards the query to the nested dictionaries: the last nested resource dictionary is searched first, and the first nested resource dictionary is searched last.
If the resource ID is not mapped to anything in this resource dictionary or any of the nested dictionaries, the function returns nullptr.

template<typename Type >

shared_ptr<Type> kanzi::ResourceDictionary::tryAcquire ( const ResourceID & key ) const

inline

Gets from the resource dictionary the resource with the resource ID you pass to the function and casts the resource to the type you specify.

See also: tryAcquire

ResourceManager::AcquireTaskSharedPtr kanzi::ResourceDictionary::acquireAsync	(	const ResourceID &	key,
		ResourceManager::AsyncAcquireFinishedCallback	func
	)		const

Acquire resource asynchronously.

If no resource URL mapping is found, an asynchronous task is not launched. Even if no asynchronous task is launched, the callback is not executed until the next time when callbacks would be executed normally.

Parameters

key	The resource ID of the resource you want to get.
func	Callback to execute when loading is complete.

Returns: Async task launched.

void kanzi::ResourceDictionary::merge ( const ResourceDictionary & preferredDictionary )

Modifies this resource dictionary by copying into this resource dictionary the contents of the resource dictionary you pass to the function.

Adds resource ID mappings, pointers to nested resource directories, and anonymous resources from the given resource directory to this resource directory. If there are duplicate values for the resource id mappings, prefers the values in the resource directory passed to the function.

Parameters

preferredDictionary The resource dictionary to which you want to merge this resource dictionary.

ResourceDictionarySharedPtr kanzi::ResourceDictionary::clone ( ) const

Duplicates a resource dictionary.

When you duplicate a resource dictionary which contains nested resource dictionaries, copies the pointers to the nested resource dictionaries but not the contents of the nested resource dictionaries (i.e. creates a shallow copy). Class that derive from ResourceDictionary must override the cloning implementation in cloneOverride.

Returns: The pointer to the duplicated resource dictionary.
