1. DynamicBean class
A super class for define a dynamic bean by inheritance.
- Use pattern
'var {propertyName}: {valueType}? by holder'to define a dynamic property in your dynamic bean class. - To define a dynamic property, the subclass property must be mutable (var), nullable (T?) and no default value.
- The
dataproperty holds all settled dynamic property name and value. By default, it's a emptyMap.
class MyBean : DynamicBean() {
var property1: String? by holder
var property2: Int? by holder
}
@Test
fun test() {
val bean = MyBean()
assertNotNull(bean.data)
assertEquals(0, bean.data.size)
// default value is null if not settled
assertNull(bean.data["property1"])
// set null value
bean.property1 = null
assertEquals(1, bean.data.size)
assertNull(bean.data["property1"])
// set not null value
bean.property1 = "value1"
assertEquals(1, bean.data.size)
assertEquals("value1", bean.data["property1"])
// set another property
bean.property2 = 123
assertEquals(2, bean.data.size)
assertEquals("value1", bean.data["property1"])
assertEquals(123, bean.data["property2"])
}
