public class VariableContainsExpressionFunction
extends AbstractFlowableVariableExpressionFunction

Checks if the value of a variable (fetched using the variableName through the variable scope) contains all of the provided values. Depending on the variable type, this means the following: - String: following StringUtils.contains(CharSequence, CharSequence) semantics for all passed values - Collection: following the Collection.contains(Object) for all passed values - Json Array: supports checking if the array contains a JsonNode for the types that are supported as variable type When the variable value is null, false is returned in all cases. When the variable value is not null, and the instance type is not one of the cases above, false will be returned.
