schemaOfClass

Creates the schema that fits the given class.

Supported types

Primitives

• int/Integer → IntSchema

• long/Long → LongSchema

• double/Double → DoubleSchema

• boolean/Boolean → BooleanSchema

• String → StringSchema

Collections

• T[] → ArraySchema, inferring the element schema recursively

• Enum<T> → EnumSchema

Generics

A Class has no type arguments, so Map and Collection are rejected here. Use schemaOfType if you have a kotlin.reflect.KType. Reflected class fields go through it. Otherwise build the schema yourself, as in MapSchema(StringSchema, DoubleSchema).

Classes

• An AS_TYPE constant, on a companion object or as a Java static → TypedClassSchema

• Anything else → ReflectedClassSchema

The casts inside are unchecked, but the returned schema always matches the class.

Cost

A class schema reflects over every field. Results are cached per class in the registry, so that cost is paid once.

Examples

// Primitive types
val intSchema = FateSchema.schemaOfClass(Int::class.java)        // IntSchema
val stringSchema = FateSchema.schemaOfClass(String::class.java)  // StringSchema

// Collections
val arraySchema = FateSchema.schemaOfClass(Array<String>::class.java)  // ArraySchema<String>
val enumSchema = FateSchema.schemaOfClass(MyEnum::class.java)           // EnumSchema<MyEnum>

// Custom classes
val userSchema = FateSchema.schemaOfClass(User::class.java)      // ReflectedClassSchema<User>
val typedSchema = FateSchema.schemaOfClass(TypedClass::class.java) // TypedClassSchema<TypedClass>
