A function is an expression that performs a task. Function defines a relation between a set of inputs and its outputs.
Expression allows new objects to be created from a registered type. Please note that to register a type at the modeling level, Using can be used.
array
Builds a sequence of values that implements the IList<object> interface. You can then use the interface properties and methods (e.g., Add, Remove, etc.) to manipulate the list.
array (exp1, exp2, exp3...)
- exp1, exp, 2: The list of expressions or values (Optional). If you don’t add any values, it will create an empty array.
Example: array ( 3.4, 145 )
Result: [3.4, 145]
Example: array ()
Result: []
(An empty array)
Example: array ( today(), 145 )
Result: [3/12/2020 12:00:00 AM, 145]
guid
Creates an instance of the GUID structure. GUID Represents a globally unique identifier (GUID). A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.
guid (value)
- value: when provided, it creates GUID based on the value. Otherwise, it generates new GUID. Pass null value to generate new GUID (Optional)
Example: guid (null)
Result: new GUID value i.e. 4e460ce4-05a8-4875-99d3-e7dd09454f55
Example: guid ()
Result: new GUID value i.e. 4e460ce4-05a8-4875-99d3-e7dd09454f55
Example: guid ('18985823-7dbd-423f-8891-16f2cb286d39')
Result: 18985823-7dbd-423f-8891-16f2cb286d39
(The string 18985823-7dbd-423f-8891-16f2cb286d39 is converted to a Guid)
resourceRead
Reads a resource by a key-value
resourceRead (key, language)
- key (String): resource key
- language (String): language name (Optional)
Example:
resourceRead ('GroupName')
Result: Group A
It returns the value of the resource defined in resources.
Example:
resourceRead ('NombreDelGrupo', 'es')
Result: Grupo A
If you have defined a resource in a specific language, you can return its value.
zip
Creates a set of new objects based on lists of properties values
zip (objectTemplate)
- objectTemplate: is an object with key-value lists of properties
Example:
names = ['Joe','Dan']
ages = [24,56]
peopleList = zip ({Name:names, Age:ages})
peopleList =
[
{
"Name" : "Joe",
"Age" : 24
},
{
"Name" : "Dan",
"Age" : 56
}
]
Example:
names = ['Joe','Dan']
ages = [24,56]
peopleList = zip (range(0,names|count())|select(x,{@'names[x]':ages[x]}))
peopleList =
{
"Joe" : 24,
"Dan" : 56
}
between
Determines whether a value is within a range.
value |between (lower, upper)
- lower(Required): Lower bound of a range. Can be a partial expression or value. When it is a value it will consider inclusive.
- upper(Required): Higher bound of a range. Can be a partial expression or value. When it is a value it will consider inclusive.
- value(Required): A value to evaluate range condition
Partial expressions are op value format. i.e. <34
Example: 3|between (1, 5)
Result: True
Example: 1|between (1, 5)
Result: True
(1 is inclusive)
Example: 5|between (1, 5)
Result: True
(5 is inclusive)
Example: 10|between (1, 5)
Result: False
Example: 5|between (1, <5)
Result: False
(Upper range is <5. So 5 is not inclusive)
