Class IterableRange<T>

java.lang.Object

com.ibm.tivoli.maximo.util.IterableRange<T>

All Implemented Interfaces:

java.lang.Iterable<Range<T>>, java.util.Iterator<Range<T>>

public class IterableRange<T>
extends java.lang.Object
implements java.lang.Iterable<Range<T>>, java.util.Iterator<Range<T>>

This is both an Iterator and Iterable for Range items. You give it a List of T objects and this iterator will expose them as Range objects for stand and end ranges. (ie, every Pair of T's is Range, provided they are within the start/end inclusion initial range. if you use "shiftByOne=true" then it will skip the first T, create a range pattern that basically goes from the end of the first range pair to the start of the next pair.

Constructor Detail

IterableRange

public IterableRange(java.util.Iterator<T> iterator,
                     boolean shift)

Lists of T's to put into the Iterator.

Parameters:

iterator -

shift - if true, the first date is skipped to create an offset pattern

IterableRange

public IterableRange(java.util.List<T> data,
                     boolean shiftByOne)

Lists of T's to put into the Iterator.

Parameters:

data -

shiftByOne - if true, the first date is skipped to create an offset pattern

Method Detail

iterator

public java.util.Iterator<Range<T>> iterator()

Specified by:

iterator in interface java.lang.Iterable<Range<T>>

hasNext

public boolean hasNext()

Specified by:

hasNext in interface java.util.Iterator<Range<T>>

next

public Range<T> next()

the Range object is reused for each .next() operation. If you need to hold onto the Range value, then use the Range.copy() to create a copy of the range.

Specified by:

next in interface java.util.Iterator<Range<T>>

remove

public void remove()

Specified by:

remove in interface java.util.Iterator<Range<T>>
