Constructors

<init>

CustomMapEditor(mapType: Class<out MutableMap<Any?, Any?>>)

Create a new CustomMapEditor for the given target type, keeping an incoming null as-is.

CustomMapEditor(mapType: Class<out MutableMap<Any?, Any?>>, nullAsEmptyMap: Boolean)

Create a new CustomMapEditor for the given target type.

If the incoming value is of the given type, it will be used as-is. If it is a different Map type or an array, it will be converted to a default implementation of the given Map type. If the value is anything else, a target Map with that single value will be created.

The default Map implementations are: TreeMap for SortedMap, and LinkedHashMap for Map.

Functions

getAsText	`open fun getAsText(): String` This implementation returns `null` to indicate that there is no appropriate text representation.
setAsText	`open fun setAsText(text: String): Unit` Convert the given text value to a Map with a single element.
setValue	`open fun setValue(value: Any): Unit` Convert the given value to a Map of the target type.
