query

public java.util.List<BatchQueryResponse> query(java.util.List<BatchQuery> batchQueries)
                                         throws java.io.IOException

Parameters:

batchQueries - The queries, you can give any requests which implement BatchQuery

Returns:

The results of queries

Throws:

java.io.IOException - GraphQl exception or network exception

parse_batch

public java.util.List<BatchQueryResponse> parse_batch(@NonNull
                                                      @NonNull okhttp3.Response response,

                                               throws java.io.IOException

Parse results of queries from GraphQl request

Parameters:

response - HTTP response

batchQueries - Queries sent, knowing the queries can imply the way how to parse the result

Returns:

Parsed results

Throws:

java.io.IOException - GraphQl exception or network exception

do_parse

public java.util.List<BatchQueryResponse> do_parse(com.fasterxml.jackson.databind.JsonNode dataRoot,
                                                   java.util.List<BatchQuery> batchQueries)
                                            throws java.io.IOException

Handle the tedious work to unmarshall. Using instance operator should be faster than refect.

Parameters:

dataRoot - JSON node root

batchQueries - Queries to indicate what the related result format is

Returns:

Parsed results

Throws:

java.io.IOException - GraphQl exception or network exception
