Class AbstractShort2ReferenceMap

java.lang.Object
  extended byit.unimi.dsi.fastutil.shorts.AbstractShort2ReferenceMap
All Implemented Interfaces:
Map, Serializable, Short2ReferenceMap
Direct Known Subclasses:
Short2ReferenceAVLTreeMap, Short2ReferenceLinkedOpenHashMap, Short2ReferenceOpenHashMap, Short2ReferenceRBTreeMap

public abstract class AbstractShort2ReferenceMap
extends Object
implements Short2ReferenceMap, Serializable

An abstract class providing basic methods for maps implementing a type-specific interface.

In particular, this class provide containsKey(Object) and Map.containsValue(Object) methods that just call the type-specific counterpart.

Method Detail

containsKey

public boolean containsKey(Object ok)
Delegates to the corresponding type-specific method.

Specified by:
containsKey in interface Map

setDefRetValue

public void setDefRetValue(Object rv)
Description copied from interface: Short2ReferenceMap
Sets the default return value. This value is returned by get(), put() and remove() to denote that the map does not contain the specified key. It is 0/false/null by default.

Specified by:
setDefRetValue in interface Short2ReferenceMap
Parameters:
rv - the new default return value.
See Also:
Short2ReferenceMap.getDefRetValue(), Short2ReferenceMap.defaultReturnValue()

getDefRetValue

public Object getDefRetValue()
Description copied from interface: Short2ReferenceMap
Gets the default return value.

Specified by:
getDefRetValue in interface Short2ReferenceMap
Returns:
the current default return value.
See Also:
Short2ReferenceMap.defaultReturnValue()

defaultReturnValue

public void defaultReturnValue(Object rv)
Description copied from interface: Short2ReferenceMap
Sets the default return value. This value is returned by get(), put() and remove() to denote that the map does not contain the specified key. It is 0/false/null by default.

Specified by:
defaultReturnValue in interface Short2ReferenceMap
Parameters:
rv - the new default return value.
See Also:
Short2ReferenceMap.defaultReturnValue()

defaultReturnValue

public Object defaultReturnValue()
Description copied from interface: Short2ReferenceMap
Gets the default return value.

Specified by:
defaultReturnValue in interface Short2ReferenceMap
Returns:
the current default return value.

putAll

public void putAll(Map m)
Puts all pairs in the given map. If the map implements the interface of this map, it uses the faster iterators.

Specified by:
putAll in interface Map
Parameters:
m - a map.

hashCode

public int hashCode()
Returns a hash code for this map. The hash code of a map is computed by summing the hash codes of its entries.

Specified by:
hashCode in interface Map
Returns:
a hash code for this map.

equals

public boolean equals(Object o)
Specified by:
equals in interface Map

toString

public String toString()
