Method Detail

bottomUpInit

public void bottomUpInit()

Description copied from interface: ValueIterator

Prepare iteration from smallest value to highest value (using ValueIterator.hasNext() / ValueIterator.next())

 ValueIterator vit = ...;
 vit.bottomUpInit();
 while(vit.hasNext()){
    int v = vit.next();
    // operate on value v here
 }

OR

Specified by:

bottomUpInit in interface ValueIterator

Overrides:

bottomUpInit in class DisposableValueIterator

topDownInit

public void topDownInit()

Description copied from interface: ValueIterator

Prepare iteration from highest value to smallest value (using ValueIterator.hasPrevious() / ValueIterator.previous())

 ValueIterator vit = ...;
 vit.topDownInit();
 while(vit.hasPrevious()){
    int v = vit.previous();
    // operate on value v here
 }

Specified by:

topDownInit in interface ValueIterator

Overrides:

topDownInit in class DisposableValueIterator

hasNext

public boolean hasNext()

Description copied from interface: ValueIterator

Returns true if the iteration has more values. (In other words, returns true if next would return valid value.)

 ValueIterator vit = ...;
 vit.bottomUpInit();
 while(vit.hasNext()){
    int v = vit.next();
    // operate on value v here
 }

OR

Returns:

true if the getIterator has more values.

hasPrevious

public boolean hasPrevious()

Description copied from interface: ValueIterator

Returns true if the iteration has more ranges. (In other words, returns true if previous would return a valid value.)

 ValueIterator vit = ...;
 vit.topDownInit();
 while(vit.hasPrevious()){
    int v = vit.previous();
    // operate on value v here
 }

Returns:

true if the getIterator has more values.

next

public int next()

Description copied from interface: ValueIterator

Compute and return the next value.

 ValueIterator vit = ...;
 vit.bottomUpInit();
 while(vit.hasNext()){
    int v = vit.next();
    // operate on value v here
 }

OR

Returns:

the next element in the iteration.

previous

public int previous()

Description copied from interface: ValueIterator

Compute and return the previous value.

 ValueIterator vit = ...;
 vit.topDownInit();
 while(vit.hasPrevious()){
    int v = vit.previous();
    // operate on value v here
 }

Returns:

the previous element in the iteration.
