public abstract class AbstractBooleanIterator
extends Object
implements BooleanIterator

An abstract class facilitating the creation of type-specific iterators.

To create a type-specific iterator you need both a method returning the next element as primitive type and a method returning the next element as an object. However, if you inherit from this class you need just one (anyone).

This class implements also a trivial version of skip(int) that uses type-specific methods; moreover, remove() will throw an UnsupportedOperationException.

Methods

Modifier and Type	Method and Description
Boolean	next() Delegates to the corresponding type-specific method.
boolean	nextBoolean() Delegates to the corresponding generic method.
void	remove() This method just throws an UnsupportedOperationException.
int	skip(int n) This method just iterates the type-specific version of next() for at most n times, stopping if Iterator.hasNext() becomes false.

Method Detail

nextBoolean

public boolean nextBoolean()

Delegates to the corresponding generic method.

Specified by:

nextBoolean in interface BooleanIterator

Returns:

the next element in the iteration.

Iterator.next()

next

public Boolean next()

Delegates to the corresponding type-specific method.

Specified by:

next in interface Iterator<Boolean>

remove

public void remove()

This method just throws an UnsupportedOperationException.

Specified by:

remove in interface Iterator<Boolean>

skip

public int skip(int n)

This method just iterates the type-specific version of next() for at most n times, stopping if Iterator.hasNext() becomes false.

Specified by:

skip in interface BooleanIterator

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.
