Sole constructor. (For invocation by subclass constructors, typically implicit.)

Method Details

advanceExact

public abstract boolean advanceExact(int target)
                              throws IOException

Advance the iterator to exactly target and return whether target has a value. target must be greater than or equal to the current doc ID and must be a valid doc ID, ie. ≥ 0 and < maxDoc.

Throws:

IOException

nextValue

public abstract double nextValue()
                          throws IOException

Iterates to the next value in the current document. Do not call this more than docValueCount() times for the document.

Throws:

IOException

docValueCount

public abstract int docValueCount()

Retrieves the number of values for the current document. This must always be greater than zero. It is illegal to call this method after advanceExact(int) returned false.
