Functions

func BlockfilePathFromIndexPath

func BlockfilePathFromIndexPath(p string) string

BlockfilePathFromIndexPath returns the path to a block file based on the path to an index file.

func IndexPathFromBlockfilePath

func IndexPathFromBlockfilePath(p string) string

IndexPathFromBlockfilePath returns the path to an index file based on the path to a block file.

Types

type IndexFile

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

IndexFile wraps a stenotype index, allowing it to be queried.

func NewIndexFile

func NewIndexFile(filename string) (*IndexFile, error)

NewIndexFile returns a new handle to the named index file.

func (*IndexFile) Close

func (i *IndexFile) Close() error

Close the indexfile.

func (*IndexFile) Dump

func (i *IndexFile) Dump(out io.Writer, start, finish []byte)

Dump writes out a debug version of the entire index to the given writer.

func (*IndexFile) IPPositions

func (i *IndexFile) IPPositions(ctx context.Context, from, to net.IP) (base.Positions, error)

IPPositions returns the positions in the block file of all packets with IPs between the given ranges. Both IPs must be 4 or 16 bytes long, both must be the same length, and from must be <= to.

func (*IndexFile) MPLSPositions

func (i *IndexFile) MPLSPositions(ctx context.Context, mpls uint32) (base.Positions, error)

MPLSPositions returns the positions in the block file of all packets with the given MPLS number.

func (*IndexFile) Name

func (i *IndexFile) Name() string

Name returns the name of the file underlying this index.

func (*IndexFile) PortPositions

func (i *IndexFile) PortPositions(ctx context.Context, port uint16) (base.Positions, error)

PortPositions returns the positions in the block file of all packets with the give port number (TCP or UDP).

func (*IndexFile) ProtoPositions

func (i *IndexFile) ProtoPositions(ctx context.Context, proto byte) (base.Positions, error)

ProtoPositions returns the positions in the block file of all packets with the give IP protocol number.

func (*IndexFile) VLANPositions

func (i *IndexFile) VLANPositions(ctx context.Context, port uint16) (base.Positions, error)

VLANPositions returns the positions in the block file of all packets with the given VLAN number.
