List operations perform various actions on a list. See below for details on these actions.
See Microflow Element Common Properties for properties that all activities share (e.g. caption). This page only describes the properties specific to the action.
A list operation action can execute any of the following types of operations.
These binary operations have as an input a list and either another list or an object. The resulting type depends on the type of the operation. All lists and objects must relate to the same entity.
|Union||The result is a combination of the elements of both parameters avoiding duplicates.||List|
|Intersect||The result is a list containing elements that appear in both parameters.||List|
|Subtract||The result is the first parameter with the element(s) of the second parameter removed.||List|
|Contains||Checks whether all elements of the second parameter are present in the first parameter.||Boolean|
|Equals||Checks whether the lists contain the same elements.||Boolean|
|Sort||Allows you to sort a list based on a number of a attributes. The attributes are ordered to determine their priority while sorting. The input list remains in its original order while the sorted list is stored in the output variable.||List|
These operations take a single list and an attribute as input. The resulting type depends on the type of the operation.
|Find||Find the first object of which the attribute has the given value.||Object|
|Filter||Find all objects of which the attribute has the given value.||List|
These unary operations have a list as input and either an object or another list as a resulting type, depending on the operation.
|Head||The result is the first element of the list, or empty if the parameter contains zero elements or was initialized as empty.||Object|
|Tail||The result is a list containing all elements of the parameter except the first, or an empty list if the parameter contains zero elements or was initialized as empty.||List|
The variable name defines the name of the resulting list, object or boolean. It can be used by all activities that follow this activity.
