Base class for resources that represent different implementations of plCustomData. More...
#include <CustomData.h>
Protected Member Functions | |
| virtual void | CreateAndLoadData (plAbstractObjectGraph &ref_graph, plRttiConverterContext &ref_context, const plAbstractObjectNode *pRootNode)=0 |
| virtual plResourceLoadDesc | UnloadData (Unload WhatToUnload) override |
| Requests the resource to unload another quality level. If bFullUnload is true, the resource should unload all data, because it is going to be deleted afterwards. | |
| plResourceLoadDesc | UpdateContent_Internal (plStreamReader *Stream, const plRTTI &rtti) |
 Protected Member Functions inherited from plResource | |
| plResource (DoUpdate ResourceUpdateThread, plUInt8 uiQualityLevelsLoadable) | |
| Default constructor. | |
| virtual | ~plResource () |
| virtual destructor. | |
| MemoryUsage & | ModifyMemoryUsage () |
| Non-const version for resources that want to write this variable directly. | |
| void | SetIsReloadable (bool bIsReloadable) |
| Call this to specify whether a resource is reloadable. | |
| void | SetHasLoadingFallback (bool bHasLoadingFallback) |
| Used internally by the code injection macros. | |
Additional Inherited Members | |
| Public Member Functions inherited from plResource | |
| PL_ALWAYS_INLINE const plString & | GetResourceID () const |
| Returns the unique ID that identifies this resource. On a file resource this might be a path. Can also be a GUID or any other scheme that uniquely identifies the resource. | |
| PL_ALWAYS_INLINE plUInt64 | GetResourceIDHash () const |
| Returns the hash of the unique ID. | |
| void | SetResourceDescription (plStringView sDescription) |
| The resource description allows to store an additional string that might be more descriptive during debugging, than the unique ID. | |
| const plString & | GetResourceDescription () const |
| The resource description allows to store an additional string that might be more descriptive during debugging, than the unique ID. | |
| const plString & | GetResourceIdOrDescription () const |
| The returns the resource description, if available, otherwise the resource ID. | |
| PL_ALWAYS_INLINE plResourceState | GetLoadingState () const |
| Returns the current state in which this resource is in. | |
| PL_ALWAYS_INLINE plUInt8 | GetNumQualityLevelsDiscardable () const |
| Returns the current maximum quality level that the resource could have. | |
| PL_ALWAYS_INLINE plUInt8 | GetNumQualityLevelsLoadable () const |
| Returns how many quality levels the resource may additionally load. | |
| float | GetLoadingPriority (plTime now) const |
| Returns the priority that is used by the resource manager to determine which resource to load next. | |
| plResourcePriority | GetPriority () const |
| Returns the current resource priority. | |
| void | SetPriority (plResourcePriority priority) |
| Changes the current resource priority. | |
| PL_ALWAYS_INLINE const plBitflags< plResourceFlags > & | GetBaseResourceFlags () const |
| Returns the basic flags for the resource type. Mostly used the resource manager. | |
| PL_ALWAYS_INLINE const MemoryUsage & | GetMemoryUsage () const |
| Returns the information about the current memory usage of the resource. | |
| PL_ALWAYS_INLINE plTime | GetLastAcquireTime () const |
| Returns the time at which the resource was (tried to be) acquired last. If a resource is acquired using plResourceAcquireMode::PointerOnly, this does not update the last acquired time, since the resource is not acquired for full use. | |
| PL_ALWAYS_INLINE plInt32 | GetReferenceCount () const |
| Returns the reference count of this resource. | |
| PL_ALWAYS_INLINE const plTimestamp & | GetLoadedFileModificationTime () const |
| Returns the modification date of the file from which this resource was loaded. | |
| PL_ALWAYS_INLINE plUInt32 | GetCurrentResourceChangeCounter () const |
| Returns the current value of the resource change counter. Can be used to detect whether the resource has changed since using it last time. | |
| PL_ALWAYS_INLINE void | IncResourceChangeCounter () |
| Allows to manually increase the resource change counter to signal that dependent code might need to update. | |
| virtual void | ResetResource () |
| If the resource has modifications from the original state, it should reset itself to that state now (or force a reload on itself). | |
| void | PrintHandleStackTraces () |
| Prints the stack-traces for all handles that currently reference this resource. | |
| Public Member Functions inherited from plReflectedClass | |
| virtual const plRTTI * | GetDynamicRTTI () const |
| bool | IsInstanceOf (const plRTTI *pType) const |
| Returns whether the type of this instance is of the given type or derived from it. | |
| template<typename T > | |
| PL_ALWAYS_INLINE bool | IsInstanceOf () const |
| Returns whether the type of this instance is of the given type or derived from it. | |
| Static Public Member Functions inherited from plNoBase | |
| static const plRTTI * | GetStaticRTTI () |
| Public Attributes inherited from plResource | |
| plEvent< const plResourceEvent &, plMutex > | m_ResourceEvents |

Base class for resources that represent different implementations of plCustomData.
These resources are automatically generated using these macros: PL_DECLARE_CUSTOM_DATA_RESOURCE(YourCustomData) PL_DEFINE_CUSTOM_DATA_RESOURCE(YourCustomData)
Put the former into a header next to YourCustomData and the latter into a cpp file.
This builds these types: YourCustomDataResource YourCustomDataResourceHandle
You can then use these to reference this resource type for example in components. For a full example search the SampleGamePlugin for SampleCustomDataResource and SampleCustomDataResourceHandle and see how they are used.
