EMPTY_ARRAY

static final Bits[] EMPTY_ARRAY

Method Details

get

boolean get(int index)

Returns the value of the bit with the specified index.

Parameters:

index - index, should be non-negative and < length(). The result of passing negative or out of bounds values is undefined by this interface, just don't do it!

Returns:

true if the bit is set, false otherwise.

length

int length()

Returns the number of bits in this set
