Class AbstractInt2BooleanMap

java.lang.Object

it.unimi.dsi.fastutil.ints.AbstractInt2BooleanFunction

it.unimi.dsi.fastutil.ints.AbstractInt2BooleanMap

All Implemented Interfaces:

Function<java.lang.Integer,java.lang.Boolean>, Int2BooleanFunction, Int2BooleanMap, java.io.Serializable, java.util.Map<java.lang.Integer,java.lang.Boolean>

Direct Known Subclasses:

Int2BooleanArrayMap

public abstract class AbstractInt2BooleanMap
extends AbstractInt2BooleanFunction
implements Int2BooleanMap, java.io.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).

Method Detail

containsValue

public boolean containsValue(java.lang.Object ov)

Specified by:

containsValue in interface java.util.Map<java.lang.Integer,java.lang.Boolean>

containsValue

public boolean containsValue(boolean v)

Checks whether the given value is contained in values().

Specified by:

containsValue in interface Int2BooleanMap

See Also:

Map.containsValue(Object)

containsKey

public boolean containsKey(int k)

Checks whether the given value is contained in keySet().

Specified by:

containsKey in interface Int2BooleanFunction

See Also:

Function.containsKey(Object)

putAll

public void putAll(java.util.Map<? extends java.lang.Integer,? extends java.lang.Boolean> m)

Puts all pairs in the given map. If the map implements the interface of this map, it uses the faster iterators.

Specified by:

putAll in interface java.util.Map<java.lang.Integer,java.lang.Boolean>

Parameters:

m - a map.

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface java.util.Map<java.lang.Integer,java.lang.Boolean>

keySet

public IntSet keySet()

Returns a type-specific-set view of the keys of this map.

The view is backed by the set returned by 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 Int2BooleanMap

Specified by:

keySet in interface java.util.Map<java.lang.Integer,java.lang.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 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 Int2BooleanMap

Specified by:

values in interface java.util.Map<java.lang.Integer,java.lang.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()

entrySet

public ObjectSet<java.util.Map.Entry<java.lang.Integer,java.lang.Boolean>> entrySet()

Description copied from interface: Int2BooleanMap

Returns a set view of the mappings contained in this map.

Note that this specification strengthens the one given in Map.entrySet().

Specified by:

entrySet in interface Int2BooleanMap

Specified by:

entrySet in interface java.util.Map<java.lang.Integer,java.lang.Boolean>

Returns:

a set view of the mappings contained in this map.

See Also:

Map.entrySet()

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 java.util.Map<java.lang.Integer,java.lang.Boolean>

Overrides:

hashCode in class java.lang.Object

Returns:

a hash code for this map.

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Map<java.lang.Integer,java.lang.Boolean>

Overrides:

equals in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
