SubspaceModifier.Node

abstract class SubspaceModifier.Node

Known direct subclasses

TestTagNode

TestTagNode

The longer-lived object that is created for each SubspaceModifierElement applied to a SubspaceLayout

Summary

Public constructors
`Node()`

Public functions
`open Unit`	`onAttach()` Called when the node is attached to a `SubspaceLayout` which is part of the UI tree.
`open Unit`	`onDetach()` Called when the node is not attached to a `SubspaceLayout` anymore.

Public properties
`Boolean`	`isAttached` Indicates that the node is attached to a `SubspaceLayout` which is part of the UI tree.

Extension functions
`Sequence<SubspaceModifier.Node>`	`SubspaceModifier.Node.traverseAncestors()` Generates a lazy sequence that walks up the node tree to the root.
`Sequence<SubspaceModifier.Node>`	`SubspaceModifier.Node.traverseDescendants()` Generates a lazy sequence that walks down the node tree.
`Sequence<SubspaceModifier.Node>`	`SubspaceModifier.Node.traverseSelfThenAncestors()` Generates a sequence with self and elements up the node tree to the root.
`Sequence<SubspaceModifier.Node>`	`SubspaceModifier.Node.traverseSelfThenDescendants()` Generates a sequence with self and elements down the node tree.

onAttach

Added in 1.0.0-alpha02

open fun onAttach(): Unit

Called when the node is attached to a SubspaceLayout which is part of the UI tree.

onDetach

Public properties

isAttached

Added in 1.0.0-alpha02

val isAttached: Boolean

Indicates that the node is attached to a SubspaceLayout which is part of the UI tree. This will get set to true right before onAttach is called, and set to false right after onDetach is called.

Extension functions

traverseAncestors

Artifact: androidx.xr.compose:compose

View Source

fun SubspaceModifier.Node.traverseAncestors(): Sequence<SubspaceModifier.Node>

Generates a lazy sequence that walks up the node tree to the root.

If this node is the root, an empty sequence is returned.

traverseDescendants

Artifact: androidx.xr.compose:compose

View Source

fun SubspaceModifier.Node.traverseDescendants(): Sequence<SubspaceModifier.Node>

Generates a lazy sequence that walks down the node tree.

If this node is a leaf node, an empty sequence is returned.

traverseSelfThenAncestors

Artifact: androidx.xr.compose:compose

View Source

fun SubspaceModifier.Node.traverseSelfThenAncestors(): Sequence<SubspaceModifier.Node>

Generates a sequence with self and elements up the node tree to the root.

traverseSelfThenDescendants
