        public boolean canConvert​(Class<?> src,
                          Class<?> dest)
        Description copied from interface: Converter
        Checks whether objects of the given class can be converted to the specified type.

        Note that this does not necessarily entail that Converter.convert(Object, Class) on a specific object of the given source class will succeed. For example: canConvert(String.class, int.class) will return true because a String can in general be converted to an int, but calling convert("5.1", int.class) will throw a NumberFormatException when the conversion is actually attempted via the Integer(String) constructor.

        Converter.convert(Object, Class)

      • convert

        public Object convert​(Object src,
                      Type dest)
        Description copied from interface: Converter
        As Converter.convert(Object, Class) but capable of creating and populating multi-element objects (Collections and array types). If a single element type is provided, it will be converted the same as Converter.convert(Object, Class). If a multi-element type is detected, then the value parameter will be interpreted as potential collection of values. An appropriate container will be created, and the full set of values will be type converted and added.

        NB: This method should be capable of creating any array type, but if a Collection interface or abstract class is provided we can only make a best guess as to what container type to instantiate; defaults are provided for Set, Queue, and List.

        Parameters:
        src - The object to convert.
        dest - Type to which the object should be converted.

      • convert

        public <T> T convert​(Object src,
                     Class<T> dest)
        Description copied from interface: Converter
        Converts the given object to an object of the specified type. The object is casted directly if possible, or else a new object is created using the destination type's public constructor that takes the original object as input (except when converting to String, which uses the Object.toString() method instead). In the case of primitive types, returns an object of the corresponding wrapped type. If the destination type does not have an appropriate constructor, returns null.
        Type Parameters:
        T - Type to which the object should be converted.
        Parameters:
        src - The object to convert.
        dest - Type to which the object should be converted.
