Class NestedTreeHolder

java.lang.Object

com.facebook.litho.LithoNode

com.facebook.litho.NestedTreeHolder

All Implemented Interfaces:

Node<LithoRenderContext>, java.lang.Cloneable

public class NestedTreeHolder
extends LithoNode

This class is a placeholder for the unresolved layout and result of a Components which implement the OnCreateLayoutWithSizeSpec.The TreeProps, padding and border width properties and held separately so that they can be copied into the actual nested tree layout before measuring it.

Constructor Detail

NestedTreeHolder

protected NestedTreeHolder(TreeProps props)

NestedTreeHolder

protected NestedTreeHolder(TreeProps props,
                           LithoNode cacheNode)

Method Detail

getCachedNode

public LithoNode getCachedNode()

When a node is measured during Component.measure and a layout-result is cached, it is cached using that node as the key. Later, this layout may resolve a nested-tree-holder node, and so in order to be able to access this cache, this node is used.

getPendingTreeProps

public TreeProps getPendingTreeProps()

border

public void border(int[] widths,
                   int[] colors,
                   float[] radii,
                   PathEffect effect)

Overrides:

border in class LithoNode

createYogaNodeWriter

protected NestedTreeYogaLayoutProps createYogaNodeWriter(YogaNode node)

Overrides:

createYogaNodeWriter in class LithoNode

copyInto

public void copyInto(LithoNode target)

transferInto

public void transferInto(LithoNode target)
