CompositionGroup

interface CompositionGroup : CompositionData

CompositionGroup is a group of data slots tracked independently by composition. These groups correspond to flow control branches (such as if statements and function calls) as well as emitting of a node to the tree.

This interface is not intended to be used directly and is provided to allow the tools API to have access to data tracked during composition. The tools API should be used instead which provides a more usable interpretation of the slot table.

Properties

compositionGroups

common

abstract val compositionGroups: Iterable<CompositionGroup>

Iterate the composition data in the group.

data

common

abstract val data: Iterable<Any?>

The data stored in the slot table for this group.

isEmpty

common

abstract val isEmpty: Boolean

Returns true if no composition data has been collected.

key

common

abstract val key: Any

A value used to identify the group within its siblings and is typically a compiler generated integer but can be an object if the key composable is used.

node

common

abstract val node: Any?

If the group represents a node this returns a non-null value which is the node that was emitted for the group.

sourceInfo

common

abstract val sourceInfo: String?

Information recorded by the compiler to help tooling identify the source that generated the group.
