List and String List

The list data type contains a sequence of strings. String list objects allow you to select lists of values, either returned from a List data type property, by converting a node list into a list of strings using the toStringList method, or by splitting a string into a string list using the Split method.

After you add a list data type property or a string list object, you can add the following methods. After you add a method, you must specify a condition for that method that can be evaluated to a Boolean value.

Method	Description	Data Type of Returned Object	Parameters	Example
`Any`	Returns True if any of the strings in a string list match the specified condition	Boolean	The condition that the string list object gets evaluated against	`node.properties.PLN.UDA (Account).any.stringItem.matches("UDA"))` will return True if any of the strings in the string list match "UDA".
`Count`	Returns a count of the strings in a list that match a specified condition	Integer	The condition that the string list object gets evaluated against	`node.properties.PLN.UDA (Account).count.stringItem.greaterThan("ABC"))` will return the number of strings in a string list whose value is greater than "ABC."
`Find`	Returns the first string in a string list that matches a specified condition	String	The condition that the string list object gets evaluated against	`node.properties.PLN.UDA (Account).find.stringItem.equals("Expense"))` returns the first string in a string list of a selected node whose name equals "Expense".
`Get`	Returns the string in a string list at the specified index	String	The index to return the string from Note: Positive index numbers (or zero) count from the first index to the last, with zero being the first index. Negative index numbers count from last to first.	`node.properties.PLN.UDA (Account).get(0)` returns the first string in the PLN.UDA (Account) string list.
`IndexOf`	Returns the position of the specified string in a string list. Note: Returns `-1` when the specified string is not found.	Integer	The specified string that you want to return the position for.	`node.ancestors[name].toStringList.indexOf(Texas)` returns the starting position of the specified string "Texas" in the string list of ancestor names for a node.
`Intersect`	Returns the common values that exist in both specified lists.	String List	A second string list that you are comparing to the first string list for common values.	`node.ancestors[name].toStringList.intersect(node.properties.UDA)` returns the common values that exist in both the list of ancestor names for a node and the node.properties.UDA string list.
`IsEmpty`	Returns `True` if the property contains either a null value or an empty string.	Boolean	None	`node.properties.PLN.UDA (Account).IsEmpty` returns True if the value of the PLN.UDA (Account) string list is null or empty.
`isNull`	Returns `True` if the property contains a null value. Note: The `isNull` method is available for list data type properties only. You cannot use `isNull` for string lists from the `toStringList` or `Split` methods.	Boolean	None	`node.properties.PLN.UDA (Account).isNull` returns True if the value of the PLN.UDA (Account) string list is null.
`Join`	Concatenates string values from a list into a delimited string using the specified delimiter	String	The delimiter that separates each string	`return.node.properties.PLN.UDA (Account).join("\|")` returns a string that consists of all of the strings in the PLN.UDA (Account) string list concatenated together and separated by "\|".
`Reverse`	Returns the string list values in the reverse order.	String List	None	`node.ancestors[name].toStringList.reverse` returns a list of ancestor names for a node in reverse order.
`Size`	Returns the number of strings in a string list Note: The `Size` method is different from `Count` in that it does not require a predicate condition.	Integer	None	`return.node.properties.PLN.UDA (Account).size` returns the number of strings in the PLN.UDA (Account) string list as a string value.
