public abstract class AbstractFloat2CharFunction extends Object implements Float2CharFunction, 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(char rv)
Description copied from interface:Float2CharFunction
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 interfaceFloat2CharFunction
- Parameters:
rv
- the new default return value.- See Also:
Float2CharFunction.defaultReturnValue()

defaultReturnValue
public char defaultReturnValue()
Description copied from interface:Float2CharFunction
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 interfaceFloat2CharFunction
- Returns:
- the current default return value.
