# Imagine we have two separate JSON objects.
jsonA = Chilkat::CkJsonObject.new()
jsonA.UpdateString("ciphertext","encryptedData")
jsonA.UpdateInt("status",200)
jsonA.UpdateString("error","errorMsg")

jsonA.put_EmitCompact(false)
print jsonA.emit() + "\n";

# jsonA contains:

# {
#   "ciphertext": "encryptedData",
#   "status": 200,
#   "error": "errorMsg"
# }

jsonB = Chilkat::CkJsonObject.new()
jsonB.UpdateString("users[0].role","Surgeon")
jsonB.UpdateNewArray("users[0].sub_roles")
jsonB.UpdateBool("users[0].viewable_for_sharing",true)
jsonB.UpdateInt("users[0].eula_create_date",123)
jsonB.UpdateString("users[1].role","Support")
jsonB.UpdateString("users[1].sub_roles[0]","Tech")
jsonB.UpdateString("users[1].sub_roles[1]","Service")
jsonB.UpdateBool("users[1].viewable_for_sharing",true)
jsonB.UpdateInt("users[1].eula_create_date",123)

jsonB.put_EmitCompact(false)
print jsonB.emit() + "\n";

# jsonB contains:

# {
#   "users": [
#     {
#       "role": "Surgeon",
#       "sub_roles": [],
#       "viewable_for_sharing": true,
#       "eula_create_date": 1649108922482
#     },
#     {
#       "role": "Support",
#       "sub_roles": [
#         "Tech",
#         "Service"
#       ],
#       "viewable_for_sharing": true,
#       "eula_create_date": 1649108951523
#     }
#   ]
# }

# Let's say we want to insert jsonB into jsonA to get this:

# {
#   "ciphertext": "encryptedData",
#   "status": 200,
#   "error": "errorMsg",
#   "users": [
#     {
#       "role": "Surgeon",
#       "sub_roles": [],
#       "viewable_for_sharing": true,
#       "eula_create_date": 1649108922482
#     },
#     {
#       "role": "Support",
#       "sub_roles": [
#         "Tech",
#         "Service"
#       ],
#       "viewable_for_sharing": true,
#       "eula_create_date": 1649108951523
#     }
#   ]
# }

# First add an empty array at the desired location (-1 means append to end).
jsonA.AddArrayAt(-1,"users")

# The destination is the empty "users" array, the source is the populated "users" array in jsonB.
# jsonUsersDest is a CkJsonArray
jsonUsersDest = jsonA.ArrayOf("users")
# jsonUsersSrc is a CkJsonArray
jsonUsersSrc = jsonB.ArrayOf("users")
# Copy the array items from source to dest
jsonUsersDest.AppendArrayItems(jsonUsersSrc)

print jsonA.emit() + "\n";

# The end result is this:

# {
#   "ciphertext": "encryptedData",
#   "status": 200,
#   "error": "errorMsg",
#   "users": [
#     {
#       "role": "Surgeon",
#       "sub_roles": [
#       ],
#       "viewable_for_sharing": true,
#       "eula_create_date": 123
#     },
#     {
#       "role": "Support",
#       "sub_roles": [
#         "Tech",
#         "Service"
#       ],
#       "viewable_for_sharing": true,
#       "eula_create_date": 123
#     }
#   ]
