Package suffixarray

Overview

Package suffixarray implements substring search in logarithmic time using an in-memory suffix array.

-

Example use:

-
// create index for some data
-index := suffixarray.New(data)
-
-// lookup byte slice s
-offsets1 := index.Lookup(s, -1) // the list of all indices where s occurs in data
-offsets2 := index.Lookup(s, 3)  // the list of at most 3 indices where s occurs in data
-

type Index

Index implements a suffix array for fast substring search.

-
type Index struct {
-    // contains filtered or unexported fields
-}
-

func New 

func New(data []byte) *Index

New creates a new Index for data. Index creation time is O(N) for N = len(data).

-

func (*Index) Bytes 

func (x *Index) Bytes() []byte

Bytes returns the data over which the index was created. It must not be modified.

-

func (*Index) FindAllIndex 

func (x *Index) FindAllIndex(r *regexp.Regexp, n int) (result [][]int)

FindAllIndex returns a sorted list of non-overlapping matches of the regular expression r, where a match is a pair of indices specifying the matched slice of x.Bytes(). If n < 0, all matches are returned in successive order. Otherwise, at most n matches are returned and they may not be successive. The result is nil if there are no matches, or if n == 0.

-

func (*Index) Lookup 

func (x *Index) Lookup(s []byte, n int) (result []int)

Lookup returns an unsorted list of at most n indices where the byte string s occurs in the indexed data. If n < 0, all occurrences are returned. The result is nil if s is empty, s is not found, or n == 0. Lookup time is O(log(N)*len(s) + len(result)) where N is the size of the indexed data.

Example -

Code:

index := suffixarray.New([]byte("banana"))
-offsets := index.Lookup([]byte("ana"), -1)
-for _, off := range offsets {
-    fmt.Println(off)
-}
-
-

Output:

1
-3
-

func (*Index) Read 

func (x *Index) Read(r io.Reader) error

Read reads the index from r into x; x must not be nil.

-

func (*Index) Write 

func (x *Index) Write(w io.Writer) error

Write writes the index x to w.
