Class Documentation
-
class MappedObjectData : public gpa::capture_support::ObjectData
Subclass of ObjectData that is used for ObjectData implementations which refer to or manage memory objects (buffers, textures, etc)
Public Types
-
typedef std::shared_ptr<MappedObjectData> Ptr
Public Functions
-
MappedObjectData()
-
~MappedObjectData()
-
virtual bool IsMappedObjectData() const override
-
virtual void Apply(ResourceDataDescriptor const *desc)
Apply the changes described in desc.
- Parameters
desc -- Describes all parameters to the Apply operation (offset into memory, number of bytes to copy, etc).
-
virtual void SaveChunkForRestore(ResourceDataDescriptor const *desc)
Track update chunks for later restore (for example, as part of a repeated range playback).
- Parameters
desc -- Resource descriptor that describes the offset into the mapped device memory, and its length in bytes.
-
virtual bool HasChunksToRestore() const
Determines if this object contains update chunks that need restoring (for example, as part of a repeated range playback).
- Returns
True if this object contains chunks for update, false otherwise
-
virtual void RestoreChunks(void *baseMappedObjectAddress)
Restore all update chunks to the mapped memory buffer whose virtual address is provided.
Note
This buffer must be large enough to accommodate all potential restore chunks; it is advised to map the entire device memory object to ensure this is the case.
- Parameters
baseMappedObjectAddress -- Starting address of the mapped memory buffer
Protected Functions
-
virtual void *GetBufferPtr() = 0
Retrieve a pointer to the mapped memory.
- Returns
Pointer to the mapped memory, or null if memory is not currently mapped
-
struct ModifiedChunk

typedef std::shared_ptr<MappedObjectData> Ptr
