All Implemented Interfaces:: Byte2BooleanFunction, Byte2BooleanMap, Function<Byte,Boolean>, Serializable, Function<Byte,Boolean>, IntPredicate, Map<Byte,Boolean>

Direct Known Subclasses:: AbstractByte2BooleanSortedMap, Byte2BooleanArrayMap, Byte2BooleanOpenCustomHashMap, Byte2BooleanOpenHashMap

public abstract class AbstractByte2BooleanMap
extends AbstractByte2BooleanFunction
implements Byte2BooleanMap, Serializable

An abstract class providing basic methods for maps implementing a type-specific interface.

Optional operations just throw an UnsupportedOperationException. Generic versions of accessors delegate to the corresponding type-specific counterparts following the interface rules (they take care of returning null on a missing key).

As a further help, this class provides a BasicEntry inner class that implements a type-specific version of Map.Entry; it is particularly useful for those classes that do not implement their own entries (e.g., most immutable maps).

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`static class`	`AbstractByte2BooleanMap.BasicEntry`	This class provides a basic but complete type-specific entry class for all those maps implementations that do not have entries on their own (e.g., most immutable maps).
`static class`	`AbstractByte2BooleanMap.BasicEntrySet`	This class provides a basic implementation for an Entry set which forwards some queries to the map.

Method Details
- containsValue
  
  public boolean containsValue(boolean v)
  
  Description copied from interface: Byte2BooleanMap
  
  Returns true if this map maps one or more keys to the specified value.
  
  Specified by:
  
  containsValue in interface Byte2BooleanMap
  
  See Also:
  
  Map.containsValue(Object)
- containsKey
  
  public boolean containsKey(byte k)
  
  Description copied from interface: Byte2BooleanMap
  
  Returns true if this function contains a mapping for the specified key.
  
  Specified by:
  
  containsKey in interface Byte2BooleanFunction
  
  Specified by:
  
  containsKey in interface Byte2BooleanMap
  
  Parameters:
  
  k - the key.
  
  Returns:
  
  true if this function associates a value to key.
  
  See Also:
  
  Map.containsKey(Object)
- isEmpty
  
  public boolean isEmpty()
  
  Specified by:
  
  isEmpty in interface Map<Byte,Boolean>
- keySet
  
  public ByteSet keySet()
  
  Returns a type-specific-set view of the keys of this map.
  The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.
  
  Specified by:
  
  keySet in interface Byte2BooleanMap
  
  Specified by:
  
  keySet in interface Map<Byte,Boolean>
  
  Returns:
  
  a set view of the keys of this map; it may be safely cast to a type-specific interface.
  
  See Also:
  
  Map.keySet()
- values
  
  public BooleanCollection values()
  
  Returns a type-specific-set view of the values of this map.
  The view is backed by the set returned by Map.entrySet(). Note that no attempt is made at caching the result of this method, as this would require adding some attributes that lightweight implementations would not need. Subclasses may easily override this policy by calling this method and caching the result, but implementors are encouraged to write more efficient ad-hoc implementations.
  
  Specified by:
  
  values in interface Byte2BooleanMap
  
  Specified by:
  
  values in interface Map<Byte,Boolean>
  
  Returns:
  
  a set view of the values of this map; it may be safely cast to a type-specific interface.
  
  See Also:
  
  Map.values()
- putAll
  
  public void putAll(Map<? extends Byte,? extends Boolean> m)
  
  Specified by:
  
  putAll in interface Map<Byte,Boolean>
- hashCode
  
  public int hashCode()
  
  Returns a hash code for this map. The hash code of a map is computed by summing the hash codes of its entries.
  
  Specified by:
  
  hashCode in interface Map<Byte,Boolean>
  
  Overrides:
  
  hashCode in class Object
  
  Returns:
  
  a hash code for this map.
- equals
  
  public boolean equals(Object o)
  
  Specified by:
  
  equals in interface Map<Byte,Boolean>
  
  Overrides:
  
  equals in class Object
- toString
  
  public String toString()
  
  Overrides:
  
  toString in class Object
