    sys::Field

Source

Field is a slot which models the ability to get and set a value.

get

virtual Obj? get(Obj? instance := null)

Source

Get the field for the specified instance. If the field is static, then the instance parameter is ignored. If the getter is non-null, then it is used to get the field.

makeSetFunc

static |Obj| makeSetFunc(Field:Obj? vals)

Source

Construct a function which sets zero or more fields on a target object. The function can be passed to a constructor which takes an it-block to reflectively set const fields. Example:

const class Foo
{
  new make(|This|? f := null) { f?.call(this) }
  const Int x
}

f := Field.makeSetFunc([Foo#x: 7])
Foo foo := Foo#.make([f])

set

virtual Void set(Obj? instance, Obj? value)

Source

Set the field for the specified instance. If the field is static, then the instance parameter is ignored. If the setter is non-null, then it is used to set the field.

type

Type type()

Source

Type stored by the field.
