Class OptionalContentOrderArray

java.lang.Object

public class OptionalContentOrderArray extends OptionalContentOrderNode
Array node class for items in the OptionalContentConfig Order array. Items in the Order array can be arranged into a tree structure; subarrays within the parent array form 'branches' of the tree. Each OptionalContentOrderArray may contain OptionalContentOrderLeafs or OptionalContentOrderArrays in a specific order; this order determines how they will appear in the 'Layers' control of the viewer.

By placing OptionalContentOrderArrays into a higher-level array, branches can be added to the tree. The 'Title' property is a string that will appear next to the expand/collapse branch control in a PDF Viewer 'Layers' panel.
