java.lang.Object net.sf.ivmaidns.util.BooleanVector
public final class BooleanVector
Class for 'boolean' array wrappers.
This class wraps a primitive boolean
-type array, and
has the possibility to resize (when required) the wrapped array.
This class supports cloning, serialization and comparison of its
instances. In addition, the class contains static
methods for boolean
arrays resizing, filling in,
reversing, vector arithmetics (logical and, or, exclusive or,
inversion), true
elements counting, searching in for
a sequence, mismatches counting, 'less-equal-greater' comparison,
and 'to-string' conversion. Important notes: boolean
arrays are not memory-efficient, so it is better to pack and
store boolean
values into int
arrays
(where it is possible).

This constructor is used for the creation of a vector which wraps

setArray(boolean[])
and by resize(int)

ensureSize(int)
methods.
