AbstractBoolean2IntFunction (fastutil 8.5.15)

java.lang.Object
- it.unimi.dsi.fastutil.booleans.AbstractBoolean2IntFunction

All Implemented Interfaces:

Boolean2IntFunction, Function<java.lang.Boolean,java.lang.Integer>, java.io.Serializable, java.util.function.Function<java.lang.Boolean,java.lang.Integer>
```
public abstract class AbstractBoolean2IntFunction
extends java.lang.Object
implements Boolean2IntFunction, 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-specific containsKey(), and size() methods.

- Method Detail
  - defaultReturnValue
```
public void defaultReturnValue(int rv)
```
    Description copied from interface: Boolean2IntFunction
    
    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 Boolean2IntFunction
    
    Parameters:
    
    rv - the new default return value.

    Boolean2IntFunction.defaultReturnValue()
  - defaultReturnValue
```
public int defaultReturnValue()
```
    Description copied from interface: Boolean2IntFunction
    
    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 Boolean2IntFunction
    
    Returns:
    
    the current default return value.
