Concrete methods

Construct a record from something else.

Type parameters

T: some type given RecordLike[T]

Value parameters

x: something that is record like

Attributes

Returns

a record

Example

 case class Person(name: String, age: Int)
 val p = Person("tarao", 3)
 val r = ArrayRecord.from(p)
 // val r: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int))] = ArrayRecord(name = tarao, age = 3)

Source

ArrayRecord.scala

Get the field value of specified label.

It is essentially the same as record.{label} but it can access to fields hidden by own methods of class ArrayRecord.

Value parameters

label: a string literal field name
record: a record

Attributes

Returns

the value of the field named by label

Example

 val r = ArrayRecord(value = 3, toString = 10)
 r.value
 // val res0: Int = 3
 r.toString
 // val res1: String = ArrayRecord(value = 3, toString = 10)
 ArrayRecord.lookup(r, "value")
 // val res2: Int = 3
 ArrayRecord.lookup(r, "toString")
 // val res3: Int = 10

Construct an array record from a JavaScript object.

Any nested type T can be converted as long as a NativeConverter[T] instance is given.

This operation is of course unsafe. Missing primitive fields become zeros or nulls and missing object fields yield java.lang.RuntimeException.

Value parameters

nc: a conversion type class
obj: a JavaScript object

Attributes

Returns

an array record

Example

 import scala.scalajs.js
 val obj: js.Any = js.Dynamic.literal(name = "tarao", age = 3)
 val r = ArrayRecord.fromJS[(("name", String), ("age", Int))](obj)
 // val r: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int))] = ArrayRecord(name = tarao, age = 3)

Construct an array record from a JSON string.

Any nested type T can be converted as long as a NativeConverter[T] instance is given.

This operation is of course unsafe. Missing primitive fields become zeros or nulls and missing object fields yield java.lang.RuntimeException.

Value parameters

json: a JSON string
nc: a conversion type class

Attributes

Returns

an array record

Example

 import scala.scalajs.js
 val json = """{"name":"tarao","age":3}"""
 val r = ArrayRecord.fromJSON[(("name", String), ("age", Int))](json)
 // val r: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int))] = ArrayRecord(name = tarao, age = 3)

Alias for concat

Attributes

Source: ArrayRecord.scala

Concatenate this record and another record.

If the both record has a field of the same name, then it takes the field from the latter record.

Type parameters

R2: a record type (given RecordLike[R2])

Value parameters

other: a record to concatenate

Attributes

Returns

a new record which has the both fields from this record and other

Example

 val r1 = ArrayRecord(name = "tarao", age = 3)
 val r2 = ArrayRecord(age = 4, email = "[email protected]")
 val r3 = r1 ++ r2
 // val r3: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int), ("email", String))] = ArrayRecord(name = tarao, age = 4, email = [email protected])

Source

ArrayRecord.scala

Give a type tag to this record.

Type parameters

T: an arbitrary type used as a tag

Attributes

Returns

the same record with a tag type

Example

 trait Person; object Person {
   extension [T <: Tuple](p: ArrayRecord[(("name", String) *: T) & Tag[Person]]) {
     def firstName: String = p.name.split(" ").head
   }
 }
 val r = ArrayRecord(name = "tarao fuguta", age = 3).tag[Person]
 r.firstName
 // val res0: String = tarao

Source

ArrayRecord.scala

Convert to a record of type %.

Attributes

Returns

a record of type %

Example

 val r1 = ArrayRecord(name = "tarao", age = 3)
 // val r1: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int))] = ArrayRecord(name = tarao, age = 3)
 r1.toRecord
 // val res0: com.github.tarao.record4s.%{val name: String; val age: Int} = %(name = tarao, age = 3)

Source

ArrayRecord.scala

Convert this record to a Tuple.

Attributes

Returns

fields of label-value pairs as a tuple

Example

 val r1 = ArrayRecord(name = "tarao", age = 3)
 r1.toTuple
 // val res0: (("name", String), ("age", Int)) = ((name,tarao),(age,3))

Source

ArrayRecord.scala

Upcast the record to specified type.

Type parameters

R2: target type

Attributes

Returns

a record containing only fields in the target type

Example

 val r1 = ArrayRecord(name = "tarao", age = 3, email = "[email protected]")
 // val r1: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int), ("email", String))] = ArrayRecord(name = tarao, age = 3, email = [email protected])
 val r2 = r1.upcast[(("name", String), ("age", Int))]
 // val r2: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int))] = ArrayRecord(name = tarao, age = 3)

Source

ArrayRecord.scala

Extend the record by fields.

If a new field has the same name as the existing field, then the new field overrides the old one.

Attributes

Returns

an object to define new fields

Example

 val r = ArrayRecord(name = "tarao") + (age = 3, email = "[email protected]")
 // val r: com.github.tarao.record4s.ArrayRecord[(("name", String), ("age", Int), ("email", String))] = ArrayRecord(name = tarao, age = 3, email = [email protected])

Source

ArrayRecord.scala

Return values of this record as a Tuple.

Attributes

Returns

values of the record as a tuple

Example

 val r1 = ArrayRecord(name = "tarao", age = 3)
 r1.values
 // val res0: (String, Int) = (tarao,3)

Any nested type T can be converted as long as a NativeConverter[T] instance is given.

Attributes

Returns
