                    currentSnapshot

Snapshot for current state without recalculating

Declaration

public var currentSnapshot: LayoutSnapshotProtocol { get }


                    
                    
                    currentRect

                    init(element:layout:constraints:)

Undocumented

Declaration

Swift

public init(element: Item?, layout: RectBasedLayout, constraints: [LayoutConstraintProtocol] = [])


                    
                    
                    layout()

Calculate and apply frames layout elements. Should be call when parent LayoutElement element has corrected bounds. Else result unexpected.

Declaration

Swift

public func layout()


                    
                    
                    layout(in:)

Calculate and apply frames layout elements in custom space.

Declaration

Swift

public func layout(in sourceRect: CGRect)

Parameters


                                sourceRect

Source space


                    
                    
                    snapshot(for:)

Returns snapshot for all LayoutElement elements in block. Attention: in during calculating snapshot frames of layout elements must not changed.

Declaration

Swift

public func snapshot(for sourceRect: CGRect) -> LayoutSnapshotProtocol

Parameters


                                sourceRect

Source space for layout

Return Value

Snapshot contained frames layout elements


                    
                    
                    snapshot(for:completedRects:)

Method for perform layout calculation in child blocks. Does not call this method directly outside LayoutBlockProtocol object. Layout block should be insert contained LayoutElement elements to completedRects

Declaration

Swift

public func snapshot(for sourceRect: CGRect, completedRects: inout [(AnyObject, CGRect)]) -> LayoutSnapshotProtocol

Parameters

`sourceRect`	Source space for layout. For not top level blocks rect should be define available bounds of block
`completedRects`	`LayoutElement` elements with corrected frame

Return Value

Frame of this block


                    
                    
                    apply(snapshot:)

Applying frames from snapshot to LayoutElement elements in this block. Snapshot array should be ordered such to match LayoutElement elements sequence.

Declaration

Swift

public func apply(snapshot: LayoutSnapshotProtocol)

Parameters


                                snapshot

Snapshot represented as array of frames.
