public class ArrayBooleanListIterator
extends java.lang.Object
implements BooleanListIterator

An iterator over an array of boolean values.

This class implements ListIterator allowing seamless integration with other APIs.

The iterator can be reset to the start if required. add() and remove() are unsupported, but set() is supported.

Constructor Detail

ArrayBooleanListIterator

public ArrayBooleanListIterator(boolean[] array)

Constructs an iterator over an array of boolean values.

The array is assigned internally, thus the caller holds a reference to the internal state of the returned iterator. It is not recommended to modify the state of the array after construction.

Parameters:

array - the array to iterate over, must not be null

Throws:

java.lang.IllegalArgumentException - if the array is null

Method Detail

copyOf

public static ArrayBooleanListIterator copyOf(boolean[] array)

Creates an iterator over a copy of an array of boolean values.

The specified array is copied, ensuring the original data is unaltered. Note that the class is not immutable due to the set methods.

Parameters:

array - the array to iterate over, must not be null

Returns:

an iterator based on a copy of the input array, not null

Throws:

java.lang.IllegalArgumentException - if the array is null

isModifiable

public boolean isModifiable()

Description copied from interface: PrimitiveIterator

Checks whether the iterator can currently be modified.

Specified by:

isModifiable in interface PrimitiveIterator<java.lang.Boolean>

Returns:

true if the modification methods of the iterator can be used

isResettable

public boolean isResettable()

Description copied from interface: PrimitiveIterator

Checks whether the iterator can be reset.

Specified by:

isResettable in interface PrimitiveIterator<java.lang.Boolean>

Returns:

true if the object can be reset

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>

nextIndex

public int nextIndex()

Specified by:

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

nextBoolean

public boolean nextBoolean()

Description copied from interface: BooleanIterator

Gets the next value from the iterator

Specified by:

nextBoolean in interface BooleanIterator

Returns:

the next available value

next

public java.lang.Boolean next()

Specified by:

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

Specified by:

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

hasPrevious

public boolean hasPrevious()

Specified by:

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

previousIndex

public int previousIndex()

Specified by:

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

previousBoolean

public boolean previousBoolean()

Description copied from interface: BooleanListIterator

Gets the previous value from the iterator.

Specified by:

previousBoolean in interface BooleanListIterator

Returns:

the previous available value

previous

public java.lang.Boolean previous()

Specified by:

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

add

public void add(boolean value)

Description copied from interface: BooleanListIterator

Adds the specified value to the list underlying the iterator at the current iteration index (optional operation).

Specified by:

add in interface BooleanListIterator

Parameters:

value - the value to add

add

public void add(java.lang.Boolean value)

Specified by:

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

Specified by:

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

Specified by:

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

set

public void set(boolean value)

Description copied from interface: BooleanListIterator

Sets the last retrieved value from the iterator (optional operation).

Specified by:

set in interface BooleanListIterator

Parameters:

value - the value to set

set

public void set(java.lang.Boolean value)

Specified by:

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

reset
