Method Details

moveToFirst
public void moveToFirst()Description copied from interface:LowLevelIterator
Move iterator to first FS in index. A subsequent call toisValid()
will succeed iff the index is non-empty.- Specified by:
moveToFirst
in interfaceLowLevelIterator
-
moveToLast
public void moveToLast()Description copied from interface:LowLevelIterator
Move iterator to last FS in index. A subsequent call toisValid()
will succeed iff the index is non-empty.- Specified by:
moveToLast
in interfaceLowLevelIterator
-
isValid
public boolean isValid()Description copied from interface:LowLevelIterator
Check if the iterator is currently valid.- Specified by:
isValid
in interfaceLowLevelIterator
- Returns:
true
iff the iterator is valid.
-
ll_get
Description copied from interface:LowLevelIterator
Return the current FS reference.- Specified by:
ll_get
in interfaceLowLevelIterator
- Returns:
- The current FS reference.
- Throws:
NoSuchElementException
- Iff the iterator is not valid.
-
moveToNext
public void moveToNext()Description copied from interface:LowLevelIterator
Advance the iterator. This may invalidate the iterator.- Specified by:
moveToNext
in interfaceLowLevelIterator
-
moveToPrevious
public void moveToPrevious()Description copied from interface:LowLevelIterator
Move the iterator back one position. This may invalidate the iterator.- Specified by:
moveToPrevious
in interfaceLowLevelIterator
-
moveTo
public void moveTo(int fsRef) Description copied from interface:LowLevelIterator
Try to position the iterator so that the current element is greater than or equal tofsRef
, and previous elements are less thanfsRef
. This may invalidate the iterator. If fsRef can not be compared to FSs in the index, the results are undefined.- Specified by:
moveTo
in interfaceLowLevelIterator
- Parameters:
fsRef
- The FS reference the iterator should be set to.
-
copy
Description copied from interface:LowLevelIterator
Create a copy of this iterator. The copy will point at the same element that this iterator is currently pointing at.- Specified by:
copy
in interfaceLowLevelIterator
- Returns:
- A copy of this iterator.
-
ll_indexSize
public int ll_indexSize()Description copied from interface:LowLevelIterator
Return the size of the underlying index.- Specified by:
ll_indexSize
in interfaceLowLevelIterator
- Returns:
- The size of the index.
-
ll_getIndex
Description copied from interface:LowLevelIterator
Get the index for just the top most type of this iterator (excludes subtypes).- Specified by:
ll_getIndex
in interfaceLowLevelIterator
- Returns:
- The index.
-
binarySearch
private final int binarySearch(int[] array, int ele, int start, int end)
