concat

open fun <Context : Any> concat(strings: List<Value<Context, String?>>): Value<Context, String?>(source)

open fun <Context : Any> concat(vararg strings: Value<Context, String?>): Value<Context, String?>(source)

@JvmName(name = "concatByField")

open fun <Context : Any> concat(vararg strings: Field<Context, String?>): Value<Context, String?>(source)

@JvmName(name = "concatByProperty")

open fun <Context : Any> concat(vararg strings: KProperty1<Context, String?>): Value<Context, String?>(source)

Concatenates strings together.

If any of strings are null, the concatenation returns null.

Example

class Document(
    val firstName: String,
    val lastName: String,
    val fullName: String,
)

collection.aggregate()
    .set {
        Document::fullName set concat(of(Document::firstName), of(" "), of(Document::lastName))
    }
    .toList()
