capacity
public int capacity() -
check
public void check()Check that all positions are in non-decreasing order. This is necesary because we use binary search to find positions -
contains
public boolean contains(int pos) -
get
public int get(int i) Get position at index 'i' -
indexOf
public int indexOf(int pos) Find the index of a position using binary search- Parameters:
pos- : A zero-based position- Returns:
- index of the position or negative number if not found
-
indexOfSlow
public int indexOfSlow(int pos) Find the index of a position using a (slow) linear search Used for testing- Parameters:
pos- : A zero-based position- Returns:
- index of the position or negative number if not found
-
set
public void set(int i, int pos) Set position to entry number 'i' -
size
public int size()Number of entries in use -
sizeBytes
public long sizeBytes()Memory size of this object (approximate size in bytes)
