public abstract class AbstractObject2ByteFunction<K> extends java.lang.Object implements Object2ByteFunction<K>, java.io.Serializable
An abstract class providing basic methods for functions implementing a type-specific interface.This class handles directly a default return value (including methods to access it). Instances of classes inheriting from this class have just to return
defRetValue
to denote lack of a key in type-specific methods. The value is serialized.Implementing subclasses have just to provide type-specific
get()
, type-specificcontainsKey()
, andsize()
methods.- See Also:

defaultReturnValue
public void defaultReturnValue(byte rv)
Description copied from interface:Object2ByteFunction
Sets the default return value (optional operation). This value must be returned by type-specific versions ofget()
,put()
andremove()
to denote that the map does not contain the specified key. It must be 0/false
/null
by default.- Specified by:
defaultReturnValue
in interfaceObject2ByteFunction<K>
- Parameters:
rv
- the new default return value.- See Also:
Object2ByteFunction.defaultReturnValue()

defaultReturnValue
public byte defaultReturnValue()
Description copied from interface:Object2ByteFunction
Gets the default return value.This default implementation just return the default null value of the type (
null
for objects, 0 for scalars, false for Booleans).- Specified by:
defaultReturnValue
in interfaceObject2ByteFunction<K>
- Returns:
- the current default return value.
