31 * \file array_internal.h
32 *
33 * <pre>
34 * Contains the following structs:
35 * struct Numa array of floats
36 * struct Numaa
37 * struct L_Dna array of doubles
38 * struct L_Dnaa
39 * struct L_Dnahash
40 * struct Sarray array of C-strings
41 * struct L_Bytea array of bytes
42 *
43 * This file can be #included after allheaders.h in source files that
44 * require direct access to the internal data fields in these structs.
45 *
46 * Here are the non-image-related arrays in leptonica:
47 * * Numa, L_Dna, L_Ptra, Sarray:
48 * These have most of the typical operations of vectors, such as add,
49 * insert, remove and replace.
50 * * Numaa, L_Dnaa, L_Ptraa:
51 * These are arrays of float, double and generic pointer arrays.
52 * * L_Bytea:
53 * This is an array of bytes, analogous to a C++ string.
54 * * L_Dnahash:
55 * This is a simple hashing for integers, used in the jbig2 classifier.
56 * </pre>
