Method Detail

flattenSortedByKey

public static final int[] flattenSortedByKey(com.carrotsearch.hppc.IntIntHashMap map)

Converts an IntIntHashMap into a flat int [] array. The returned arrays contains [key,value] pairs and is sorted in ascending order by key values.

flatten

public static final int[] flatten(com.carrotsearch.hppc.IntIntHashMap map)

Converts an IntIntHashMap into a flat int [] array. Even indexes in the flat array represent keys and the corresponding odd indexes -- values. Note: the order of keys in the flat array is arbitrary.

addAllFromFlattened

public static final com.carrotsearch.hppc.IntIntHashMap addAllFromFlattened(com.carrotsearch.hppc.IntIntHashMap map,
                                                      int[] flattened)

Adds all entries from a flat [] array to the provided map. Even indexes in the flat array represent keys and the corresponding odd indexes -- values.

Returns:

the input map for convenience
