Detailed Description

template<class T>
class AZ::Data::Asset< T >

Asset is a smart pointer to an actual asset. Asset users should always refer to assets using this object.

Constructor & Destructor Documentation

◆ Asset()

template<class T >

AZ::Data::Asset< T >::Asset ( AssetLoadBehavior loadBehavior = AssetLoadBehavior::Default )

Create asset with default params (no asset bounded) By default, referenced assets will be queued for load during serialization. Use AssetLoadBehavior to control this behavior.

Asset<T>

Member Function Documentation

◆ Create() [1/2]

template<class T >

bool AZ::Data::Asset< T >::Create	(	const AssetId &	id,
		AssetLoadBehavior	loadBehavior,
		bool	queueLoad = `false`
	)

Create an asset with an ID and loadBehavior (type is inferred). If there is a current asset it will be released.

Parameters

id	AssetId
loadBehavior	AssetLoadBehavior
queueLoad	if true it will call "QueueLoad" to load the asset data.

◆ Create() [2/2]

template<class T >

bool AZ::Data::Asset< T >::Create	(	const AssetId &	id,
		bool	queueLoad = `false`
	)

Create an asset with an ID (type is inferred). If there is a current asset it will be released.

Parameters

id	AssetId
queueLoad	if true it will call "QueueLoad" to load the asset data.

◆ GetAutoLoadBehavior()

template<class T >

AssetLoadBehavior AZ::Data::Asset< T >::GetAutoLoadBehavior ( ) const

Returns: auto load behavior for the asset reference.

◆ GetFlags()

template<class T >

u8 AZ::Data::Asset< T >::GetFlags ( ) const

Returns asset instance flags Deprecated - use GetAutoLoadBehavior

◆ QueueLoad()

template<class T >

bool AZ::Data::Asset< T >::QueueLoad ( const AssetLoadParameters & loadParams = {} )

If the asset is not loaded and has a valid id, it will be queued for load.

Returns

true if the load was queued (you can listen on the AssetBus or check with IsReady) and false if the queue of loading did not happen. There are multiple reasons for this and you can test in case of error. Current failure conditions:

Invalid id

◆ Release()

template<class T >

bool AZ::Data::Asset< T >::Release ( )

Releases reference on asset data, if one is held. The asset ID, hint, etc are all still preserved.

Returns: true if a reference was held, and therefore released.

◆ Reload()

template<class T >

bool AZ::Data::Asset< T >::Reload ( )

Reloads an asset if an asset is create.

Returns: true if reload is triggered, otherwise false if an asset is not created (ie. We don't have asset ID to reload)

◆ Reset()

template<class T >

bool AZ::Data::Asset< T >::Reset ( )

Fully resets the Asset to a clean initialized state. The asset data is released, the asset ID is reset, the hint is cleared, etc.

◆ Save()

template<class T >

bool AZ::Data::Asset< T >::Save ( )

Save asset, triggers a SaveAsset of possible AssetDatabase::SaveAsset.

◆ SetAutoLoadBehavior()

template<class T >

void AZ::Data::Asset< T >::SetAutoLoadBehavior ( AssetLoadBehavior loadBehavior )

Sets the auto load behavior for the asset reference.

Parameters

ref AssetLoadBehavior

◆ SetFlags()

template<class T >

bool AZ::Data::Asset< T >::SetFlags ( u8 flags )

You can change the flags only when we don't have an asset bound (ie. GetData() == null) Deprecated - use SetAutoLoadBehavior

◆ ToString() [1/2]

template<class T >

template<class StringType >

StringType AZ::Data::Asset< T >::ToString ( ) const

inline

for debugging purposes - creates a string that represents the assets id, subid, hint, and name. You should use this function for any time you want to show the full details of an asset in a log message as it will always produce a consistent output string. By convention, don't surround the output of this call with any kind of decorator, (for example, don't format like [s]) because decorators are built-in.

◆ ToString() [2/2]

template<class T >

template<class StringType >

void AZ::Data::Asset< T >::ToString ( StringType & result ) const

inline

for debugging purposes only - updates a string that represents the asset's id, subid, hint and name. see comment details on StringType ToString() above.

◆ UpgradeAssetInfo()

template<class T >

void AZ::Data::Asset< T >::UpgradeAssetInfo ( )

Upgrades legacy Ids/hints with the new canonical Ids/hints. This will search for the assetId and hint in the catalog and if found, will update it to be the new, canonical one(s)
