DictionaryGet Node

The DictionaryGet Node gets a key to the Input Port, looks up for the key in the Dictionary Collection, receives a value for the key, and sends the value to the Output Port.

The DictionaryGet Node has the following Input Ports:

key Input Port (named by default) gets the name of the key, ex. "key" = "ID1".

The value for the key is represented by an arbitrary number of elements, objects, arrays of JSON structure.

This means that the elements may be requested by the query to the element in the JSON structure.

If the requested element is absent then the DictionaryGet Node will returnes a Null value to the Output Port.

The DictionaryGet Node allows to add Output Ports to request any specified elements, objects or arrays collected for the key.

The DictionaryGet Node performs a look up in the Collection and returns the value to the Output Port (unnamed by default):

query Output Port (unnamed by default) returnes the value for the specified element, object or array in the JSON structure, ex. for the object -> A returnes the value -> {"ts": 1000000000, "key": "A", "value": 1}`.

The DictionaryGet Node has the following Configuration Parameters:

Collection Name to address the Dictionary.

In the example above the the DictionaryGet Node requests the ABCD Collection for the "key" : "ID1" and receives the following “values” for the specified "keys":

for the object A returnes the value {"ts": 1000000000, "key": "A", "value": 1};
for the number B returnes the value 3.14;
for the integer C returnes the value 42;
for the boolean D returnes the value True;
for the string E returnes the value Hello, World!;
for the array F returnes the value [1, 2, 3, 4, 5].
