AbstractFloatCollection (fastutil 6.5.1)

java.lang.Object
- java.util.AbstractCollection<Float>
- - it.unimi.dsi.fastutil.floats.AbstractFloatCollection

All Implemented Interfaces:

FloatCollection, FloatIterable, Iterable<Float>, Collection<Float>

Direct Known Subclasses:

AbstractFloatBigList, AbstractFloatList, AbstractFloatSet, FloatCollections.EmptyCollection, FloatCollections.IterableCollection
```
public abstract class AbstractFloatCollection
extends AbstractCollection<Float>
implements FloatCollection
```
An abstract class providing basic methods for collections implementing a type-specific interface.
In particular, this class provide iterator(), add(), remove(Object) and contains(Object) methods that just call the type-specific counterpart.

Method Summary

Methods
Modifier and Type	Method and Description
`boolean`	`add(float k)`
`boolean`	`add(Float o)` Delegates to the corresponding type-specific method.
`boolean`	`addAll(Collection<? extends Float> c)` Adds all elements of the given collection to this collection.
`boolean`	`addAll(FloatCollection c)` Adds all elements of the given type-specific collection to this collection.
`boolean`	`contains(float k)`
`boolean`	`contains(Object o)` Delegates to the corresponding type-specific method.
`boolean`	`containsAll(Collection<?> c)` Checks whether this collection contains all elements from the given collection.
`boolean`	`containsAll(FloatCollection c)` Checks whether this collection contains all elements from the given type-specific collection.
`FloatIterator`	`floatIterator()` Deprecated.
`boolean`	`isEmpty()`
`abstract FloatIterator`	`iterator()` Returns a type-specific iterator on the elements of this collection.
`boolean`	`rem(float k)` Note that this method should be called `remove()`, but the clash with the similarly named index-based method in the `List` interface forces us to use a distinguished name.
`boolean`	`rem(Object o)` Delegates to the corresponding type-specific method.
`boolean`	`remove(Object ok)` Delegates to the type-specific `rem()` method.
`boolean`	`removeAll(Collection<?> c)` Remove from this collection all elements in the given collection.
`boolean`	`removeAll(FloatCollection c)` Remove from this collection all elements in the given type-specific collection.
`boolean`	`retainAll(Collection<?> c)` Retains in this collection only elements from the given collection.
`boolean`	`retainAll(FloatCollection c)` Retains in this collection only elements from the given type-specific collection.
`Object[]`	`toArray()`
`float[]`	`toArray(float[] a)` Returns a primitive type array containing the items of this collection.
`<T> T[]`	`toArray(T[] a)` Returns an containing the items of this collection; the runtime type of the returned array is that of the specified array.
`float[]`	`toFloatArray()` Returns a primitive type array containing the items of this collection.
`float[]`	`toFloatArray(float[] a)` Returns a primitive type array containing the items of this collection.
