getBitsPerValue
public abstract int getBitsPerValue()- Returns:
- the number of bits used to store any given value. Note: This does not imply that
memory usage is
bitsPerValue * #valuesas implementations are free to use non-space-optimal packing of bits.
-
set
public abstract void set(int index, long value) Set the value at the given index in the array.- Parameters:
index- where the value should be positioned.value- a value conforming to the constraints set by the array.
-
set
public int set(int index, long[] arr, int off, int len) Bulk set: set at least one and at mostlenlongs starting atoffinarrinto this mutable, starting atindex. Returns the actual number of values that have been set. -
fill
public void fill(int fromIndex, int toIndex, long val) Fill the mutable fromfromIndex(inclusive) totoIndex(exclusive) withval. -
clear
public void clear()Sets all values to 0.
