Detailed Description

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

Definition at line 44 of file filesystemAsset.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 ( ) const
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 ( ) const
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.

static AR_API ArTimestamp ArFilesystemAsset::GetModificationTimestamp ( const ArResolvedPath resolvedPath)
static

Returns an ArTimestamp holding the mtime of the file at resolvedPath. Returns an invalid ArTimestamp if the mtime could not be retrieved.

virtual AR_API size_t ArFilesystemAsset::GetSize ( ) const
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 
) const
overridevirtual

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

Implements ArAsset.
