Function
Most function implementations will have some knowledge of the intended number of keys in their domain. In some cases, however, this might not be possible. This default implementation, in particular, returns -1.
public double defaultReturnValue()
Object2DoubleFunction
This default implementation just return the default null value
of the type (null
for objects, 0 for scalars, false for Booleans).

Note that for some kind of functions (e.g., hashes) this method will always return true. This default implementation, in particular, always return true.
