isPrimitiveBacked¶

Whether the given KaType is backed by a single JVM primitive type.

This is true for non-nullable primitive types and for non-nullable inline value class types whose single underlying property is primitive-backed, recursively. It is false for nullable types, regular reference types, and types without a single primitive-backed representation.

Only the inline representation counts. A full value class is compiled as a regular class on the JVM, so it is never primitive-backed, even with exactly one primary property; see org.jetbrains.kotlin.analysis.api.symbols.KaNamedClassSymbol.isInline.

This property describes the type's underlying representation. It does not imply that every use of the type is emitted as a JVM primitive, as boxing can still be required by the use-site context.

For non-JVM modules, the result describes the equivalent JVM representation inferred from the Kotlin declaration.
