Method Detail
-
clone
public Object clone()
Disclaimer: If the value type doesn't implementclone(), only the reference is copied. Note: Due to private fields we cannot implement a copy constructor, sorry.
-
containsValue
public boolean containsValue(int value)
-
containsKey
public boolean containsKey(int key)
-
get
public int get(int key)
Returns the value to which the specified key is mapped, orgetKeyNotFoundValue()if this map contains no mapping for the key.
-
put
public int put(int key, int value)Maps the key to the specified value. If a mapping to this key already exists, the previous value will be returned (otherwisegetKeyNotFoundValue()).
-
putAll
public void putAll(IntIntHashMap source)
Copies all of the mappings from the specified map to this map.
-
remove
public int remove(int key)
Removes the key-value mapping from this map. Returns the previously mapped value orgetKeyNotFoundValue()if no such mapping exists.
-
size
public int size()
Returns the current number of key-value mappings in this map.
-
capacity
public int capacity()
Returns the current capacity (buckets) in this map.
-
clear
public void clear()
Clears the entire map. The size is 0 after this operation.
-
iterator
public Iterator<IntIntHashMap.Entry> iterator()
Returns a newIterator. Note: this Iterator does not yet support removal of elements.- Specified by:
iteratorin interfaceIterable<IntIntHashMap.Entry>
-
setKeyNotFoundValue
public int setKeyNotFoundValue(int newKeyNotFoundValue)
Sets the new key not found value. For primitive types (int, long) the default is -1, for Object types, the default is null.- Returns:
- the previous key not found value
- See Also:
get(int),put(int, int)
-
getKeyNotFoundValue
public int getKeyNotFoundValue()
Returns the value which is returned if no value has been found for the specified key.- See Also:
get(int),put(int, int)
-
toString
public StringBuilder toString(StringBuilder sb)
- Parameters:
sb- if null, a new StringBuilder is created- Returns:
- StringBuilder instance with appended string information of this Entry
