Class TSutraLayerStructure

Unit

LayerStructureUnit

Declaration

type TSutraLayerStructure = class(TCustomLayerStructure)

Description

TLayerOwnerCollection is a TEnhancedOrderedCollection that stores of list of TDataArrays that it can delete. The list (NewDataSets) is not created by the TLayerOwnerCollection. Instead another class creates it and assigns it to TLayerOwnerCollection. TUndoChangeLgrPackageSelection is an example of a class that assigns NewDataSets.

When a new TDataArray is created, it should be added to NewDataSets using AddOwnedDataArray; In DoCommand, ClearNewDataSets should be called before the TDataArrays are created. In Undo, RemoveNewDataSets should be called;
