sortnode properties

Sort node icon The Sort node sorts records into ascending or descending order based on the values of one or more fields.

Example

node = stream.create("sort", "My node")
node.setPropertyValue("keys", [["Age", "Ascending"], ["Sex", "Descending"]])
node.setPropertyValue("default_ascending", False)
node.setPropertyValue("use_existing_keys", True)
node.setPropertyValue("existing_keys", [["Age", "Ascending"]])

Table 1. sortnode properties
`sortnode` properties	Data type	Property description
`keys`	list	Specifies the fields you want to sort against. If no direction is specified, the default is used.
`default_ascending`	flag	Specifies the default sort order.
`use_existing_keys`	flag	Specifies whether sorting is optimized by using the previous sort order for fields that are already sorted.
`existing_keys`		Specifies the fields that are already sorted and the direction in which they are sorted. Uses the same format as the `keys` property.
`default_sort_order`	`Ascending` `Descending`	Specify whether, by default, records are sorted in ascending or descending order of the sort key values.
