Detailed Description

The FileSystem class identifies the file system type associated with a file.

Definition at line 24 of file file_system.h.

Constructor & Destructor Documentation

pp::FileSystem::FileSystem ( )

Constructs an is_null() filesystem resource. If you use this constructor, you will have to assign it to a "real" FileSystem object before you can use it.

pp::FileSystem::FileSystem ( const FileSystem other)

The copy constructor for FileSystem.

[in]otherA reference to a FileSystem.
pp::FileSystem::FileSystem ( const Resource resource)

Constructs a FileSystem from a Resource.

[in]resourceA Resource containing a file system.
pp::FileSystem::FileSystem ( PassRef  ,
PP_Resource  resource 

A constructor used when you have received a PP_Resource as a return value that has already been reference counted.

[in]resourceA PP_Resource corresponding to a PPB_FileSystem.
pp::FileSystem::FileSystem ( const InstanceHandle instance,
PP_FileSystemType  type 

This constructor creates a file system object of the given type.

[in]instanceThe instance with which this resource will be associated.
[in]typeA file system type as defined by PP_FileSystemType enum.

Member Function Documentation

static bool pp::FileSystem::IsFileSystem ( const Resource resource)

Checks whether a Resource is a file system, to test whether it is appropriate for use with the FileSystem constructor.

[in]resourceA Resource to test.
True if resource is a file system.
int32_t pp::FileSystem::Open ( int64_t  expected_size,
const CompletionCallback cc 

Open() opens the file system. A file system must be opened before running any other operation on it.

[in]expected_sizeThe expected size of the file system. Note that this does not request quota; to do that, you must either invoke requestQuota from JavaScript: or set the unlimitedStorage permission for Chrome Web Store apps:
[in]ccA PP_CompletionCallback to be called upon completion of Open().
An int32_t containing an error code from pp_errors.h.
