AutofillTree

Class

Common

Deprecated " Use the new semantics-based Autofill APIs androidx.compose.ui.autofill.ContentType and androidx.compose.ui.autofill.ContentDataType instead. "

class 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

Properties

Common

val children: MutableMap<Int, @Suppress("Deprecation") AutofillNode>

A map which contains AutofillNodes, where every node represents an autofill-able field.

Functions

operator fun plusAssign(autofillNode: @Suppress("Deprecation") AutofillNode)

Add the specified AutofillNode to the AutofillTree.

fun performAutofill(id: Int, value: String) = children[id]?.onFill?.invoke(value)

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