Modifier	Constructor	Description
protected	Iterator(AbstractSparseArray.Node head, int fromdir, boolean fForward)	Instantiate a new PrimitiveIterator at the specified location and direction.

Method Summary

Modifier and Type	Method	Description
long	getPrimitiveValue()	Returns the current value, which is the same value returned by the most recent call to the nextPrimitive method, or the most recent value passed to setPrimitiveValue if setPrimitiveValue were called after the nextPrimitive method.
long	nextPrimitive()	Returns the next element (as a long) in the iteration.
long	setPrimitiveValue(long lValue)	Stores a new value at the current value index, returning the value that was replaced.

Constructor Detail

Iterator

protected Iterator(AbstractSparseArray.Node head,
                   int fromdir,
                   boolean fForward)

Instantiate a new PrimitiveIterator at the specified location and direction.

Parameters:

head - the node at which to start the crawl

fromdir - the direction in which to start the crawl

Method Detail

nextPrimitive

public long nextPrimitive()

Returns the next element (as a long) in the iteration.

Returns:

the next element (as a long) in the iteration

Throws:

NoSuchElementException - iteration has no more elements

getPrimitiveValue

public long getPrimitiveValue()

Returns the current value, which is the same value returned by the most recent call to the nextPrimitive method, or the most recent value passed to setPrimitiveValue if setPrimitiveValue were called after the nextPrimitive method.

Returns:

the current value

Throws:

IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.

setPrimitiveValue

public long setPrimitiveValue(long lValue)

Stores a new value at the current value index, returning the value that was replaced. The index of the current value is obtainable by calling the getIndex method.

Returns:

the replaced value

Throws:

IllegalStateException - if the next method has not yet been called, or the remove method has already been called after the last call to the next method.
