Constructor Detail

IntLongHppcOpenHashMap

public IntLongHppcOpenHashMap()

IntLongHppcOpenHashMap

public IntLongHppcOpenHashMap(int initialCapacity)

IntLongHppcOpenHashMap

public IntLongHppcOpenHashMap(int initialCapacity,
                      float loadFactor)

Method Detail

createFrom

public static IntLongHppcOpenHashMap createFrom(IntIterable keys,
                                LongIterable values)

createFrom

public static IntLongHppcOpenHashMap createFrom(int[] keys,
                                long[] values)

createForAdd

public static IntLongHppcOpenHashMap createForAdd(int count,
                                  float loadFactor)

Creates new hashmap with the specified load factor that is garanteed to not invoke resize after adding count elements

Returns:

new hashmap with the specified capacity dependent on count and loadFactor

createForAdd

public static IntLongHppcOpenHashMap createForAdd(int count)

Creates new hashmap with default load factor

See Also:

createForAdd(int, float)

containsKey

public boolean containsKey(int key)

Returns:

true if this map contains key key. Otherwise false

size

public int size()

Returns:

the number of keys/values in this map(its cardinality)

iterator

@NotNull
public IntLongIterator iterator()

Returns:

fail-fast read-only iterator for the collection. If Iterable represents empty collection it should return IntLongIterator.EMPTY

keysIterator

public IntIterator keysIterator()

valuesIterator

public LongIterator valuesIterator()

get

public long get(int key)

Returns:

the value for the specified key if this map contains key key. Otherwise returns default value.

clear

public void clear()

Description copied from interface: WritableIntLongMap

Removes all entries from this map.

putImpl

protected long putImpl(int key,
           long value)

Description copied from class: AbstractWritableIntLongMap

put element without invocation of AbstractWritableIntLongMap#modified()

Specified by:

putImpl in class AbstractWritableIntLongMap

putOrAdd

public long putOrAdd(int key,
            long putValue,
            long additionValue)

Trove-inspired API method. An equivalent of the following code:

  if (containsKey(key))
  {
      long v = (long) (lget() + additionValue);
      lset(v);
      return v;
  }
  else
  {
     put(key, putValue);
     return putValue;
  }
 

Parameters:

key - The key of the value to adjust.

putValue - The value to put if key does not exist.

additionValue - The value to add to the existing value if key exists.

Returns:

Returns the current value associated with key (after changes).

addTo

public long addTo(int key,
         long additionValue)

lget

public long lget()

Returns the last value saved in a call to containsKey(int).

See Also:

containsKey(int)

lset

public long lset(long value)

Sets the value corresponding to the key saved in the last call to containsKey(int), if and only if the key exists in the map already.

Returns:

Returns the previous value stored under the given key.

See Also:

containsKey(int)

lslot

public int lslot()

Returns:

Returns the slot of the last key looked up in a call to containsKey(int) if it returned true.

See Also:

containsKey(int)

removeImpl

protected long removeImpl(int key)

Description copied from class: AbstractWritableIntLongMap

remove element without invocation of AbstractWritableIntLongMap#modified()

Specified by:

removeImpl in class AbstractWritableIntLongMap

remove

public boolean remove(int key,
             long value)

Description copied from interface: WritableIntLongMap

Removes the entry for the key only if the key is currently mapped to the given value.

Specified by:

remove in interface WritableIntLongMap

Overrides:

remove in class AbstractWritableIntLongMap

Returns:

true if the size of this map has changed. Otherwise false.
