List functions are useful for working with list or array data types. The functions provided can help you extract list values and manipulate a list order.
List Functions
First
The First Function returns the first element of a list.
Configuration:
You can configure the Node Label and Description on this function. There are no other configurable fields. The function should be connected to a node that passes in a List/Array of values.
Example:
Input list,
["one", "two", "three"]
Output,
"one"
Join
The join function returns a new String composed of copies of the CharSequence elements joined together with a copy of the specified delimiter.
Note that if an element is null, then this function ignores null values.
Configuration:
1. Enter a label for the node. This will be helpful with identifying the node when viewing your Entity Pipeline.
2. Enter a Description that will explain the criteria configured.
3. Enter the Delimiter to be used when joining each value in a list.
4. The Insert Token option allows you to set as a field token in order to dynamically set the delimiter value.
Example
Input List: ["one","two","three"]
Delimiter: -
Output value: one-two-three
Last
The Last Function returns the last element of a list.
Configuration:
You can configure the Node Label and Description on this function. There are no other configurable fields. The function should be connected to a node that passes in a List/Array of values.
Example:
Input list,
["one", "two", "three"]
Output,
"three"
Reverse
The Reverse Function reverses the order of the elements in a given list.
Configuration:
You can configure the Node Label and Description on this function. There are no other configurable fields. The function should be connected to a node that passes in a List/Array of values
Example:
Input List,
["one", "two", "three"]
Output,
["three", "two", "one"]
Sort
Sort can be used to sort elements of a given list in ascending order. It is based on the underlying core Java java.lang.Comparable interface.
Configuration:
You can configure the Node Label and Description on this function. There are no other configurable fields. The function should be connected to a node that passes in a List/Array of values.
Example:
Input List,
[2,1,4,3]
Output,
[1,2,3,4]
Remove Duplicates
Remove Duplicates function is used to remove duplicate elements in a given list. It retains the order of the original list.
Configuration:
Only input configuration to this function is "Input List". This is typically a token that resolves to a List value. If this configuration is empty, then the input to this function would be used to remove duplicates.
Note: This function only works with List which has primitive types like String, Integer and Double.
Example:
Input List,
[2, 1, 2, 3, 4, 1]
Output,
[2, 1, 3, 4]
