class SemanticsNode

kotlin.Any
↳	androidx.ui.core.semantics.SemanticsNode

A node that represents some semantic data.

Summary

Public constructors
`<init>(unmergedConfig: SemanticsConfiguration, componentNode: SemanticsComponentNode)` Creates a semantic node.

Companion functions

SemanticsNode.findClosestParentNode(selector: (SemanticsNode) -> Boolean)

Executes selector on every parent of this SemanticsNode and returns the closest SemanticsNode to return true from selector or null if selector returns false for all ancestors.

SemanticsNode(
    unmergedConfig: SemanticsConfiguration, 
    componentNode: SemanticsComponentNode)

Creates a semantic node.

Each semantic node has a unique identifier that is assigned when the node is created.

val attached: Boolean

Whether this node is in a tree whose root is attached to something.

This becomes true during the call to attach.

This becomes false during the call to detach.

val boundsInRoot: PxBounds

The bounding box for this node relative to the root of this Compose hierarchy

val children: List<SemanticsNode>

Contains the children in inverse hit test order (i.e. paint order).

var componentNode: ComponentNode

val config: SemanticsConfiguration

The merged configuration of this node

val globalBounds: PxBounds

val hasChildren: Boolean

Whether this node has a non-zero number of children.

val id: Int

The unique identifier for this node.

The root node has an id of zero. Other nodes are given a unique id when they are created.

val isSemanticBoundary: Boolean

var parent: SemanticsNode?

The parent of this node in the tree.

val size: IntPxSize

The size of the bounding box for this node

val unmergedChildren: List<SemanticsNode>

var unmergedConfig: SemanticsConfiguration
