Parameters:

transform - a transformation function

Method Detail

apply

public final JsonValue apply(JsonValue value)

Description copied from interface: Function

Applies this function to the input parameter value and returns the result.

Specified by:

apply in interface Function<JsonValue,JsonValue,JsonValueException>

Parameters:

value - The input parameter.

Returns:

The result of applying this function to value.

traverseList

protected Object traverseList(JsonValue value)

Transform a JsonValue List into another object. Default implementation is to return a new ArrayList filled with the elements on which we applied the transformations.

Parameters:

value - the value to transform

Returns:

the transformed value

traverseMap

Parameters:

value - the value to transform

Returns:

the transformed value
