Detailed Description

ArAsset implementation for asset represented by a file on a filesystem.

Definition at line 47 of file filesystemAsset_v1.h.

Constructor & Destructor Documentation

AR_API ArFilesystemAsset::ArFilesystemAsset ( FILE *  file )

explicit

Constructs an ArFilesystemAsset for the given file. The ArFilesystemAsset object takes ownership of file and will close the file handle on destruction.

AR_API ArFilesystemAsset::~ArFilesystemAsset

(

)

Closes the file owned by this object.

Member Function Documentation

virtual AR_API std::shared_ptr<const char> ArFilesystemAsset::GetBuffer ( )

overridevirtual

Creates a read-only memory map for the file held by this object and returns a pointer to the start of the mapped contents.

Implements ArAsset.

virtual AR_API std::pair<FILE*, size_t> ArFilesystemAsset::GetFileUnsafe ( )

overridevirtual

Returns the FILE* handle this object was created with and an offset of 0, since the asset's contents are located at the beginning of the file.

Implements ArAsset.

virtual AR_API size_t ArFilesystemAsset::GetSize ( )

overridevirtual

Returns the size of the file held by this object.

Implements ArAsset.

static AR_API std::shared_ptr<ArFilesystemAsset> ArFilesystemAsset::Open ( const ArResolvedPath &  resolvedPath )

static

Constructs a new ArFilesystemAsset for the file at resolvedPath. Returns a null pointer if the file could not be opened.

virtual AR_API size_t ArFilesystemAsset::Read ( void *  buffer, size_t  count, size_t  offset  )

overridevirtual

Reads count bytes from the file held by this object at the given offset into buffer.

Implements ArAsset.
