Dictionary Contains Key

Type: dict-contains-key  ·  Package: Collections Activities v1.0.0  ·  Output: boolean

Checks if a dictionary contains a key and saves true/false to a variable. Use it before reading a value to avoid unexpected nulls.

How it works

Checks whether key key exists in dict and saves the result to outputVariable.

Required parameters

Parameter	Editor	Description
dict	expression	The dictionary.
key	expression	The key to check.
outputVariable	nombre de variable	Variable where to save the result.

Example

Dictionary Contains Key   dict = = config   key = "timeout"   outputVariable = tiene
If   condition = = !tiene
 └─ then:
      Set Dictionary Value   dict = = config   key = "timeout"   value = 30000   // valor by default
