## Grouped Tags Detail

### `EsaBwt`

Defined in
  <seqan/index.h>

The Burrows-Wheeler table.

The Burrows-Wheeler table contains the Burrows-Wheeler transformation of `EsaRawText`. The entries are the characters left of the corresponding suffix in the suffix array `EsaSA`.

Fibre returns the same type for `EsaRawText` and for `EsaBwt`.

### `EsaChildtab`

Defined in
  <seqan/index.h>

The child table.

The child table contains structural information of the suffix tree (see Abhouelda et al.).

Fibre returns a String over the alphabet of a size type.

### `EsaIsa`

Defined in
  <seqan/index.h>

The inverse suffix array.

The inverse suffix array stores the lexicographic rank of each suffix of `EsaRawText`.

Fibre returns a String over the alphabet of a size type.

### `EsaLcp`

Defined in
  <seqan/index.h>

The lcp table.

The lcp table contains the lcp-value of two adjacent suffices in the suffix array `EsaSA`.

Fibre returns a String over the alphabet of a size type.

### `EsaLcpe`

Defined in
  <seqan/index.h>

The lcpe table.

### `EsaRawText`

Defined in
  <seqan/index.h>

The raw text the index is really based on.

`EsaText` and `EsaRawText` fibres are equal by default. They differ if the index text is a set of strings. Then, raw text is the concatenation of all strings in this set.

### `EsaSA`

Defined in
  <seqan/index.h>

The suffix array.

The suffix array contains the indices of all suffices of `EsaRawText` in lexicographical order.

Fibre returns a String over the alphabet of the SAValue of `TIndex`.

### `EsaText`

Defined in
  <seqan/index.h>

The original text the index should be based on.
