Method Detail

seekAbsoluteIndex

void seekAbsoluteIndex(int absIndex)

Positions the iterator such that the next call to TokenValuedIterator.stepNext() will advance to the specified absolute index if the index exists. If the index doesn't exist, the next call to stepNext will either return false, indicating that the specified absoluteIndex is larger than any other in the list or true, in which case the absoluteIndex will be greater than than specified.

Parameters:

absIndex - the absolute index to seek
