Constructor Detail

ObjectTransferable

public ObjectTransferable(Object value,
                          String humanName)

Creates a transferable with a single value. Note that the representation class will be value.getClass (). To use a different representation class (eg an interface of value), use the array version of this constructor instead and ensure the array's component class type is the desired interface type.

ObjectTransferable

public ObjectTransferable(Object[] values,
                          String humanName)

Create a transferable containing a list of values. The representation class of the supported flavors will be array.getComponentType ().
