it.unimi.dsi.fastutil.floats.AbstractFloat2DoubleMap

All Implemented Interfaces:: Float2DoubleFunction, Float2DoubleMap, Function<Float,Double>, Serializable, DoubleUnaryOperator, Function<Float,Double>, Map<Float,Double>

Direct Known Subclasses:: AbstractFloat2DoubleSortedMap, Float2DoubleArrayMap, Float2DoubleOpenCustomHashMap, Float2DoubleOpenHashMap

public abstract class AbstractFloat2DoubleMap
extends AbstractFloat2DoubleFunction
implements Float2DoubleMap, 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`	`AbstractFloat2DoubleMap.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`	`AbstractFloat2DoubleMap.BasicEntrySet`	This class provides a basic implementation for an Entry set which forwards some queries to the map.

Method Summary

Modifier and Type	Method	Description
`boolean`	`containsKey(float k)`	Returns true if this function contains a mapping for the specified key.
`boolean`	`containsValue(double v)`	Returns `true` if this map maps one or more keys to the specified value.
`boolean`	`equals(Object o)`
`int`	`hashCode()`	Returns a hash code for this map.

`void`	`putAll(Map<? extends Float,? extends Double> m)`
`String`	`toString()`
`DoubleCollection`	`values()`	Returns a type-specific-set view of the values of this map.
