java - Hibernate Search vs Circular relationships -


good day.

i have situation, similar 1 presented below.

@entity @table(name="entitydo") public class entitydo {     @id     private long id;      @column(nullable = false)     private string name;      @onetomany(mappedby = "parententity")     private set<entitydo> ownedentities;      @manytoone     @joincolumn(name="parent_id", nullable=true)     private entitydo parententity;      ... }

i need index entity via hibernate search in such way, there ability search entities matched not entity name, matching parent's name in hierarchy.

my thinking following:

  1. i need recursively index 'name' member of indexed entity + 'name' of entity's parent + further etc. in such way came same lucene document's field.

  2. then able create simple query on 1 field retrieve needed entities.

in fact, have problem point 1. @indexedembedded doesn't suit here, due circular relationship , fact empty prefixes forbidden (i don't want names of entities , parents in different fields).

is possible entity indexing in custom way? or maybe thinking wrong , there approach resolve such issues?

if want index parent name field name, write own custom bridge - http://docs.jboss.org/hibernate/stable/search/reference/en-us/html_single/#d0e4426. 1 thing have careful detect circular dependencies.

if have given max depth use @indexedembedded , @ query build time add query terms fields configured max depth. whether solution viable depend on how deep want index. jsut couple of levels prefer option on custom bridge.

opencv - DataType<cv::detail::deriv_type>::depth what is it used for -

i wondering why line used in lucas kanade tracker in opencv: datatype<cv::detail::deriv_type>::depth can explain me? in opencv, depth of mat refers type of data contained in mat 's data buffer. represented integer values correspond given data type. these integers commonly abstracted appropriate macro definition (e.g. uchar data represented macro cv_8u ). cv::datatype type-traits class provides method obtain corresponding integer value without having memorize macro means data type. there few cases user code needs use datatype::depth . more common datatype::type . a simple example shows 1 possible use of datatype::depth : cv::mat uchar_data = cv::mat::ones(3, 3, cv_8uc1); cv::mat float_data; uchar_data.convertto(float_data, cv::datatype<float>::depth); // ^^ equivalently replaced // cv_32f macro float_data.at<float>(0,1) += 0.5f; std::cout << float_data << std::endl;...

python 3.x - Mapping specific letters onto a list of words -

can please suggest approach write piece of codes automatically maps letter in letter_str onto dic_key (a dict key string type contains dashes match length of words in word_lst)? so, mapping occurs if letter appears in every words in list @ same position no matter how many words in list. if no letter appears @ position words in word list new_dic_key '----'. please see examples below thanks word_lst = ['ague', 'bute', 'byre', 'came', 'case', 'doze'] dic_key = '----' letters_str ='abcdefghijklmnopqrstuvwxyz' new_dic_key = '---e' if word_list = ['bute', 'byre'] new_dic_key = 'b--e' or word_list = ['drek', 'drew', 'dyes'] new_dic_key = 'd-e-' if words in word_list of same length code give want: word_list = ['drek', 'drew', 'dyes'] cols = [] in range(len(word_list[0])): cols.append([]) word in ...
