type Blank struct{}

Blank parseable can be embedded within other parseables in order to include default nil implementations of the interface

func (Blank) Globs

func (b Blank) Globs() ([]string, []string)

func (Blank) IDs

func (b Blank) IDs() []string

func (Blank) Infos

func (b Blank) Infos() map[string]FormatInfo

func (Blank) MIMEs

func (b Blank) MIMEs() ([]string, []string)

type FormatInfo

type FormatInfo interface {
	String() string
}

FormatInfo is Identifier-specific information to be retained for the Identifier.

type Mirror

type Mirror struct{ Parseable }

Mirror reverses the PREV wild segments within signatures as SUCC/EOF wild segments so they match at EOF as well as BOF.

func (Mirror) Signatures

func (m Mirror) Signatures() ([]frames.Signature, []string, error)

Signatures returns a signature set with corresponding IDs and weights for the bytematcher.

type Parseable

type Parseable interface {
	IDs() []string                                               // list of all IDs in identifier
	Infos() map[string]FormatInfo                                // identifier specific information
	Globs() ([]string, []string)                                 // signature set and corresponding IDs for globmatcher
	MIMEs() ([]string, []string)                                 // signature set and corresponding IDs for mimematcher
	XMLs() ([][2]string, []string)                               // signature set and corresponding IDs for xmlmatcher
	Signatures() ([]frames.Signature, []string, error)           // signature set and corresponding IDs for bytematcher
	Zips() ([][]string, [][]frames.Signature, []string, error)   // signature set and corresponding IDs for container matcher - Zip
	MSCFBs() ([][]string, [][]frames.Signature, []string, error) // signature set and corresponding IDs for container matcher - MSCFB
	RIFFs() ([][4]byte, []string)                                // signature set and corresponding IDs for riffmatcher
	Texts() []string                                             // IDs for textmatcher
	Priorities() priority.Map                                    // priority map
