Types

type Matcher

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

Matcher is returned by NewMatcher and contains a list of blices to match against

func NewMatcher

func NewMatcher(dictionary [][]byte) *Matcher

NewMatcher creates a new Matcher used to match against a set of blices

func NewStringMatcher

func NewStringMatcher(dictionary []string) *Matcher

NewStringMatcher creates a new Matcher used to match against a set of strings (this is a helper to make initialization easy)

func (*Matcher) Contains

func (m *Matcher) Contains(in []byte) bool

This returns true if any string matches. It can be faster if you do not need to know which words matched.

func (*Matcher) ContainsStr

func (m *Matcher) ContainsStr(in string) bool

The same as Contains but takes in a string as a parameter.

func (*Matcher) Match

func (m *Matcher) Match(in []byte) []int

Match searches in for blices and returns all the blices found as indexes into the original dictionary
