How do I create a StaticTableSchema for a nested bean (like for the items property here)?
data class Order(
var id: Long = 0L,
var items: List<OrderLineItem> = emptyList(),
…
)
data class OrderLineItem(
var id: Long = 0L,
var price: BigDecimal = 0.0.toBigDecimal(),
…
)
First, create a TableSchema implementation for the nested bean. It could be a StaticTableSchema or a BeanTableSchema:
val orderLineItemStaticTableSchema = TableSchema
.builder(OrderLineItem::class.java)
.newItemSupplier(::OrderLineItem)
.addAttribute(Long::class.java) {
it.name("id").getter(OrderLineItem::id::get).setter(OrderLineItem::id::set)
}
.addAttribute(BigDecimal::class.java) {
it.name("price").getter(OrderLineItem::price::get).setter(OrderLineItem::price::set)
}
.build()
// or
val orderLineItemBeanTableSchema = TableSchema.fromBean(OrderLineItem::class.java)
Then, use this schema instance with EnhancedType.documentOf():
val tableSchema = TableSchema
.builder(Order::class.java)
.newItemSupplier(::Order)
.addAttribute(Long::class.java) {
it.name("id").getter(Order::id::get).setter(Order::id::set)
}
.addAttribute(
EnhancedType.listOf(
EnhancedType.documentOf(OrderLineItem::class.java, orderLineItemTableSchema)
)
) {
it.name("items").getter(Order::items::get).setter(Order::items::set)
}
.build()
