SKSequence Protocol Reference


                    
                    
                    SequenceElement

Undocumented

Swift

associatedtype SequenceElement : SKSequence


                    
                    
                    index

The zero-based pre-order depth-first search (DFS) index of the substructure relative to the source file.

Note

The first entity in each source file will begin from zero.

Note

The parents are not compared for equality.

Swift

var index: Int? { get set }


                    
                    
                    filePath

The path to the source file.

Note

The parents are not compared for equality.

Swift

var filePath: String? { get set }


                    
                    
                    internalParent

The parent entity, or nil if this entity is a root.

Important

The use of SKFinalSubclass.parent should be preferred.

Note

The parents are not compared for equality.

Swift

var internalParent: SequenceElement? { get set }


                    
                    
                    internalChildren

The entity children contained in the particular entity (sub-classes, references, etc.).

Important

The use of SKFinalSubclass.children should be preferred.

Swift

var internalChildren: [SequenceElement]? { get set }


                    
                    
                    iteratorClass()

Overridden by subclasses to substitute a new iterator class for SKChildren.

The default iterator class used is SKPreOrderDFSIterator, which is a pre-order (NLR) depth-first search (DFS) traversing iterator.

Swift

static func iteratorClass<SequenceElement>() -> SKPreOrderDFSIterator<SequenceElement>.Type where SequenceElement : SKSequence

The iterator class used for iterating through SKChildren.
