public abstract class AbstractByteCollection
extends java.util.AbstractCollection<java.lang.Byte>
implements ByteCollection
```
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

All Methods Instance Methods Abstract Methods Concrete Methods Deprecated Methods
Modifier and Type	Method and Description
`boolean`	`add(byte k)`
`boolean`	`add(java.lang.Byte o)` Delegates to the corresponding type-specific method.
`boolean`	`addAll(ByteCollection c)` Adds all elements of the given type-specific collection to this collection.
`boolean`	`addAll(java.util.Collection<? extends java.lang.Byte> c)` Adds all elements of the given collection to this collection.
`ByteIterator`	`byteIterator()` Deprecated.
`boolean`	`contains(byte k)`
`boolean`	`contains(java.lang.Object o)` Delegates to the corresponding type-specific method.
`boolean`	`containsAll(ByteCollection c)` Checks whether this collection contains all elements from the given type-specific collection.
`boolean`	`containsAll(java.util.Collection<?> c)` Checks whether this collection contains all elements from the given collection.
`boolean`	`isEmpty()`
`abstract ByteIterator`	`iterator()` Returns a type-specific iterator on the elements of this collection.
`boolean`	`rem(byte 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(java.lang.Object o)` Delegates to the corresponding type-specific method.
`boolean`	`remove(java.lang.Object ok)` Delegates to the type-specific `rem()` method.
`boolean`	`removeAll(ByteCollection c)` Remove from this collection all elements in the given type-specific collection.
`boolean`	`removeAll(java.util.Collection<?> c)` Remove from this collection all elements in the given collection.
`boolean`	`retainAll(ByteCollection c)` Retains in this collection only elements from the given type-specific collection.
`boolean`	`retainAll(java.util.Collection<?> c)` Retains in this collection only elements from the given collection.
`java.lang.Object[]`	`toArray()`
`byte[]`	`toArray(byte[] 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.
`byte[]`	`toByteArray()` Returns a primitive type array containing the items of this collection.
`byte[]`	`toByteArray(byte[] a)` Returns a primitive type array containing the items of this collection.
