Method Detail

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<java.lang.Boolean>

Specified by:

hasNext in interface java.util.ListIterator<java.lang.Boolean>

hasPrevious

public boolean hasPrevious()

Description copied from interface: BidirectionalIterator

Returns whether there is a previous element.

Specified by:

hasPrevious in interface BidirectionalIterator<java.lang.Boolean>

Specified by:

hasPrevious in interface java.util.ListIterator<java.lang.Boolean>

Returns:

whether there is a previous element.

See Also:

ListIterator.hasPrevious()

nextBoolean

public boolean nextBoolean()

Description copied from interface: BooleanIterator

Returns the next element as a primitive type.

Specified by:

nextBoolean in interface BooleanIterator

Returns:

the next element in the iteration.

See Also:

Iterator.next()

previousBoolean

public boolean previousBoolean()

Description copied from interface: BooleanBidirectionalIterator

Returns the previous element as a primitive type.

Specified by:

previousBoolean in interface BooleanBidirectionalIterator

Returns:

the previous element in the iteration.

See Also:

ListIterator.previous()

nextIndex

public int nextIndex()

Specified by:

nextIndex in interface java.util.ListIterator<java.lang.Boolean>

previousIndex

public int previousIndex()

Specified by:

previousIndex in interface java.util.ListIterator<java.lang.Boolean>

skip

public int skip(int n)

Description copied from interface: BooleanBidirectionalIterator

Skips the given number of elements.

The effect of this call is exactly the same as that of calling BooleanIterator.next() for n times (possibly stopping if Iterator.hasNext() becomes false).

Specified by:

skip in interface BooleanBidirectionalIterator

Specified by:

skip in interface BooleanIterator

Specified by:

skip in interface ObjectBidirectionalIterator<java.lang.Boolean>

Specified by:

skip in interface ObjectIterator<java.lang.Boolean>

Parameters:

n - the number of elements to skip.

Returns:

the number of elements actually skipped.

See Also:

Iterator.next()

back

public int back(int n)

Description copied from interface: BooleanBidirectionalIterator

Moves back for the given number of elements.

The effect of this call is exactly the same as that of calling BooleanBidirectionalIterator.previous() for n times (possibly stopping if BidirectionalIterator.hasPrevious() becomes false).

Specified by:

back in interface BooleanBidirectionalIterator

Specified by:

back in interface ObjectBidirectionalIterator<java.lang.Boolean>

Parameters:

n - the number of elements to skip back.

Returns:

the number of elements actually skipped.

See Also:

BooleanBidirectionalIterator.previous()

clone

public java.lang.Object clone()
