(Unicode C) Load a JsonArrayDemonstrates how to load a JsonArray. Note: This example requires Chilkat v9.5.0.64 or greater.
#include <C_CkJsonArrayW.h> #include <C_CkJsonObjectW.h> void ChilkatSample(void) { HCkJsonArrayW a; HCkJsonObjectW json; HCkJsonArrayW abc; // This example requires Chilkat v9.5.0.64 or greater. // Loading into a new JSON array is simple and straightforward. a = CkJsonArrayW_Create(); CkJsonArrayW_Load(a,L"[ 1,2,3,4 ]"); // Output: [1,2,3,4] wprintf(L"%s\n",CkJsonArrayW_emit(a)); wprintf(L"--------\n"); // The JsonArray's Load and LoadSb methods have a peculiar behavior when // it is already part of a JSON document. In this case, the JsonArray // becomes detached, and the original document remains unchanged. // This is intentional due to the nature of the internal implementation. // For example: json = CkJsonObjectW_Create(); CkJsonObjectW_Load(json,L"{ \"abc\": [ 1,2,3,4 ] }"); // Output: (json) {"abc":[1,2,3,4]} wprintf(L"(json) %s\n",CkJsonObjectW_emit(json)); wprintf(L"--------\n"); abc = CkJsonObjectW_ArrayOf(json,L"abc"); // When Load is called, abc becomes it's own document, and the original is not modified. CkJsonArrayW_Load(abc,L"[ 5,6,7,8 ]"); // Output: (abc) [5,6,7,8] wprintf(L"(abc) %s\n",CkJsonArrayW_emit(abc)); wprintf(L"--------\n"); // Output: (json) {"abc":[1,2,3,4]} wprintf(L"(json) %s\n",CkJsonObjectW_emit(json)); wprintf(L"--------\n"); CkJsonArrayW_Dispose(abc); CkJsonArrayW_Dispose(a); CkJsonObjectW_Dispose(json); } |
