Types ¶

type GFD ¶

type GFD [0x10]byte

GFD is a structure to store the fd, eventloop index, connStore indexes.

func NewGFD ¶

func NewGFD(fd, elIndex, row, column int) (gfd GFD)

NewGFD creates a new GFD.

func (GFD) ConnMatrixColumn ¶

func (gfd GFD) ConnMatrixColumn() int

ConnMatrixColumn returns the connMatrix column index.

func (GFD) ConnMatrixRow ¶

func (gfd GFD) ConnMatrixRow() int

ConnMatrixRow returns the connMatrix row index.

func (GFD) EventLoopIndex ¶

func (gfd GFD) EventLoopIndex() int

EventLoopIndex returns the eventloop index.

func (GFD) Fd ¶

func (gfd GFD) Fd() int

Fd returns the underlying fd.

func (GFD) Sequence ¶

func (gfd GFD) Sequence() uint32

Sequence returns the monotonic sequence, only used to prevent fd duplication.

func (*GFD) UpdateIndexes ¶

func (gfd *GFD) UpdateIndexes(row, column int)

UpdateIndexes updates the connStore indexes.

func (GFD) Validate ¶

func (gfd GFD) Validate() bool

Validate checks if the GFD is valid.
