Method Summary

Modifier and Type	Method	Description
(package private) long	delGen()	Returns delGen for this packet.
int	docID()	Returns the following: -1 if DocIdSetIterator.nextDoc() or DocIdSetIterator.advance(int) were not called yet.
(package private) boolean	hasValue()	Returns true if this doc has a value
int	nextDoc()	Advances to the next document in the set and returns the doc it is currently on, or DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the set. NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior.
protected abstract void	set(long idx)	Called when the iterator moved to the next document

Method Detail

nextDoc

public final int nextDoc()

Description copied from class: DocIdSetIterator

Advances to the next document in the set and returns the doc it is currently on, or DocIdSetIterator.NO_MORE_DOCS if there are no more docs in the set.
NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior.

Specified by:

nextDoc in class DocValuesFieldUpdates.Iterator

set

protected abstract void set(long idx)

Called when the iterator moved to the next document

Parameters:

idx - the internal index to set the value to

docID

public final int docID()

Description copied from class: DocIdSetIterator

Returns the following:

• -1 if DocIdSetIterator.nextDoc() or DocIdSetIterator.advance(int) were not called yet.
• DocIdSetIterator.NO_MORE_DOCS if the iterator has exhausted.
• Otherwise it should return the doc ID it is currently on.

Specified by:

docID in class DocIdSetIterator

delGen

final long delGen()

Description copied from class: DocValuesFieldUpdates.Iterator

Returns delGen for this packet.

Specified by:

delGen in class DocValuesFieldUpdates.Iterator

hasValue

final boolean hasValue()

Description copied from class: DocValuesFieldUpdates.Iterator

Returns true if this doc has a value

Specified by:
