class AutofillTree

kotlin.Any
↳	androidx.compose.ui.autofill.AutofillTree

The autofill tree is a temporary data structure that is used before the Semantics Tree is implemented. This data structure is used by compose components to set autofill hints (via AutofillNodes). It is also used by the autofill framework to communicate with Compose components (by calling performAutofill).

The AutofillTree will be replaced by Autofill Semantics (b/138604305).

Since this is a temporary implementation, it is implemented as a list of children, which is essentially a tree of height = 1

Summary

Public constructors
<init>() The autofill tree is a temporary data structure that is used before the Semantics Tree is implemented.

Public methods
Unit?	performAutofill(id: Int, value: String) The autofill framework uses this function to 'fill' the AutofillNode represented by id with the specified value.
operator Unit	plusAssign(autofillNode: AutofillNode) Add the specified AutofillNode to the AutofillTree.

Properties
MutableMap<Int, AutofillNode>	children A map which contains AutofillNodes, where every node represents an autofillable field.

Public methods

performAutofill

fun performAutofill(
    id: Int, 
    value: String
): Unit?

The autofill framework uses this function to 'fill' the AutofillNode represented by id with the specified value.

plusAssign

operator fun plusAssign(autofillNode: AutofillNode): Unit

Add the specified AutofillNode to the AutofillTree.

Properties

children

val children: MutableMap<Int, AutofillNode>

A map which contains AutofillNodes, where every node represents an autofillable field.
