AbstractShort2BooleanFunction (fastutil 8.2.3)

java.lang.Object
- it.unimi.dsi.fastutil.shorts.AbstractShort2BooleanFunction

All Implemented Interfaces:

Function<Short,Boolean>, Short2BooleanFunction, Serializable, Function<Short,Boolean>, IntPredicate

Direct Known Subclasses:

AbstractShort2BooleanMap, Short2BooleanFunctions.EmptyFunction, Short2BooleanFunctions.Singleton, Short2BooleanFunctions.UnmodifiableFunction
```
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.

- Method Detail
  - defaultReturnValue
```
public void defaultReturnValue(boolean rv)
```
    Description copied from interface: Short2BooleanFunction
    
    Sets the default return value (optional operation). This value must be returned by type-specific versions of get(), put() and remove() to denote that the map does not contain the specified key. It must be 0/false/null by default.
    
    Specified by:
    
    defaultReturnValue in interface Short2BooleanFunction
    
    Parameters:
    
    rv - the new default return value.

```
public boolean defaultReturnValue()
```
    Description copied from interface: Short2BooleanFunction
    
    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 interface Short2BooleanFunction
    
    Returns:
    
    the current default return value.
