- All Implemented Interfaces:

public abstract class AbstractShort2BooleanFunction extends Object implements Short2BooleanFunction, 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-specific containsKey(), and size() methods.

defaultReturnValue
public void defaultReturnValue(boolean rv)Description copied from interface:Short2BooleanFunctionSets 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/nullby default.- Specified by:
defaultReturnValuein interfaceShort2BooleanFunction- Parameters:
rv- the new default return value.- See Also:
Short2BooleanFunction.defaultReturnValue()

defaultReturnValue
public boolean defaultReturnValue()Description copied from interface:Short2BooleanFunctionGets the default return value.This default implementation just return the default null value of the type (
nullfor objects, 0 for scalars, false for Booleans).- Specified by:
defaultReturnValuein interfaceShort2BooleanFunction- Returns:
- the current default return value.
