Method Detail

set

public Bound3 set(Bound3 bound)

Description copied from class: Bound3

Copies the value of a (possibly empty) bound into this one. Subclasses should check if the bound type is compatible.

Specified by:

set in class Bound3

Parameters:

bound - Bound to be copied. Never null.

Returns:

Reference to this bound. Never null.

isEmpty

public boolean isEmpty()

Description copied from class: Bound3

Returns true if the bound is empty, because it has never been set, it has been cleared, or as the result of a null intersection. Note that a zero volume bound is not neccessarily empty.

Specified by:

isEmpty in class Bound3

Returns:

True if the bound is empty.

clear

public Bound3 clear()

Description copied from class: Bound3

Clears the bound by clearing its components (zero position, zero volume) and setting it empty.

Specified by:

clear in class Bound3

Returns:

Reference to this bound. Never null.
