Metamodel

sealed class Metamodel<T>

Metalastic Metamodel types Hierarchy

Sealed class for all metamodel types in the DSL. Provides path traversal functionality for nested field access. Using sealed class ensures exhaustive pattern matching and type safety.

Functions

fieldClass

fun fieldClass(): KClass<out T & Any>?

Returns the KClass for this field's type, or null if the type is not a concrete class (e.g., if it's a type parameter or complex type intersection).

fieldType

fun fieldType(): KType

Returns the Kotlin KType carried by this field, as captured at generation time.

isNestedPath

fun isNestedPath(): Boolean

Returns true if any ancestor container is marked as nested in Elasticsearch.

name

fun name(): String

Returns the local Elasticsearch field name, without any parent path segments.

nestedPaths

fun nestedPaths(): Sequence<String>

Returns the paths of the ancestor containers that are marked as nested, closest first.

parent

abstract fun parent(): Container<*>?

Returns the direct parent container in the metamodel hierarchy, or null for a root.

parents

fun parents(): Sequence<Container<*>>

Returns the sequence of ancestor containers, starting with the direct parent.

path

fun path(): String

Returns the dot-separated Elasticsearch path of this field, built from its ancestor chain.
