Types

type Asset

type Asset struct {
	// contains filtered or unexported fields
}

Asset wraps the NDK AAsset handle.

func NewAssetFromPointer

func NewAssetFromPointer(ptr unsafe.Pointer) *Asset

NewAssetFromPointer wraps a raw AAsset pointer.

func (*Asset) Buffer

func (h *Asset) Buffer() unsafe.Pointer

Buffer returns the value directly.

func (*Asset) Close

func (h *Asset) Close() error

Close releases the underlying NDK handle.

func (*Asset) IsAllocated

func (h *Asset) IsAllocated() int32

IsAllocated returns the value directly.

func (*Asset) Length

func (h *Asset) Length() Off_t

Length returns the value directly.

func (*Asset) Length64

func (h *Asset) Length64() Off64_t

Length64 returns the value directly.

func (*Asset) OpenFileDescriptor

func (h *Asset) OpenFileDescriptor(outStart *Off_t, outLength *Off_t) error

OpenFileDescriptor calls the underlying NDK function.

func (*Asset) OpenFileDescriptor64

func (h *Asset) OpenFileDescriptor64(outStart *Off64_t, outLength *Off64_t) error

OpenFileDescriptor64 calls the underlying NDK function.

func (*Asset) Pointer

func (h *Asset) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*Asset) Read

func (h *Asset) Read(buf unsafe.Pointer, count uint64) error

Read calls the underlying NDK function.

func (*Asset) RemainingLength

func (h *Asset) RemainingLength() Off_t

RemainingLength returns the value directly.

func (*Asset) RemainingLength64

func (h *Asset) RemainingLength64() Off64_t

RemainingLength64 returns the value directly.

func (*Asset) Seek

func (h *Asset) Seek(offset Off_t, whence int32) Off_t

Seek returns the value directly.

type Dir

type Dir struct {
	// contains filtered or unexported fields
}

Dir wraps the NDK AAssetDir handle.

func NewDirFromPointer

func NewDirFromPointer(ptr unsafe.Pointer) *Dir

NewDirFromPointer wraps a raw AAssetDir pointer.

func (*Dir) Close

func (h *Dir) Close() error

Close releases the underlying NDK handle.

func (*Dir) NextFileName

func (h *Dir) NextFileName() string

NextFileName returns the value directly.

func (*Dir) Pointer

func (h *Dir) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

func (*Dir) Rewind

func (h *Dir) Rewind()

Rewind calls the underlying NDK function.

type Error

type Error int32

Error represents an NDK error code.

func (Error) Error

func (e Error) Error() string

type Manager

type Manager struct {
	// contains filtered or unexported fields
}

Manager wraps the NDK AAssetManager handle.

func NewManagerFromPointer

func NewManagerFromPointer(ptr unsafe.Pointer) *Manager

NewManagerFromPointer wraps a raw AAssetManager pointer.

func (*Manager) Open

func (h *Manager) Open(filename string, mode Mode) *Asset

Open creates a new Asset from this Manager.

func (*Manager) OpenDir

func (h *Manager) OpenDir(dirName string) *Dir

OpenDir creates a new Dir from this Manager.

func (*Manager) Pointer

func (h *Manager) Pointer() unsafe.Pointer

Pointer returns the underlying pointer as unsafe.Pointer.

type Mode

type Mode int32

const (
	Unknown   Mode = 0
	Random    Mode = 1
	Streaming Mode = 2
	Buffer    Mode = 3
)

type Off64_t

type Off64_t = capi.Off64_t

type Off_t

type Off_t = capi.Off_t
