Spring Social Yahoo is an extension based on Spring Social that provides functionality to communicate with the Yahoo Social Rest API. You can find the full documentation at Yahoo's developer website. Before proceeding with using this library, please consult the Notes section. The best way to learn how use the library is to consult the Spring Social documentation and apply those principles for the classes specific to Yahoo.

Do not hesitate to point out any issues and I am very open to suggestions, both in terms of implementation and documentation

• first version release

• not all endpoints and functionalities are implemented from tha Yahoo Social API; if there are requests to implement some extras, please leave me a message and I will oblige with a response
• when implementing a connection repository, note that the default JdbcUsersConnectionRepository.sql constructs a table whose max length for the access token is 255, which is less than the length of the token received from Yahoo (about 700 characters), so you need to copy the original JdbcUsersConnectionRepository.sql file and modify the max length of the accessToken column (you can go for 1000 max length)
• you can give spring-social-yahoo a try by cloning the forked repo of spring-social-samples, available on my account at https://github.com/gabrielruiu/spring-social-samples/tree/master/spring-social-quickstart
• most classes contain links to the Yahoo documentation website, so you can consult the information there as well
• I would appreciate very much if you would take the time to give me a short email describing your usage of this library, just so I can get a feeling of how useful the library is

• if you want to build a filter for the Contacts resource (see ContactsFilter), you will most likely be using several enums to construct it:

ContactsFilter filter = new ContactsFilter()
        .withAndFilter(FieldType.EMAIL, SearchFilter.SearchFilterKey.PRESENT, "1")
        .sortBy(FieldType.EMAIL)
        .sortOrder(SortOrder.Order.DESC);
Contacts contacts = yahoo.contactsOperations().getContacts(filter);

These enums can take up some space on a single line, so to reduce the clutter, use static imports for each enum:

import static org.springframework.social.yahoo.filter.SearchFilter.SearchFilterConstraint.PRESENT;
import static org.springframework.social.yahoo.filter.SortOrder.Order.DESC;
import static org.springframework.social.yahoo.module.FieldType.EMAIL;

///other code
ContactsFilter filter = new ContactsFilter()
        .withAndFilter(EMAIL, PRESENT, "1")
        .sortBy(EMAIL)
        .sortOrder(DESC);
Contacts contacts = yahoo.contactsOperations().getContacts(filter);

• the documentation website crashes from time to time and cannot be accessed, it comes and goes
• calls to individual field resources fail with 404 responses
• the Yahoo Social API Explorer is unavailable, probably lack of maintenance; see details here

• only JSON payloads are used
• only the Contacts API is implemented
• the following endpoints are implemented:
