Class IteratorUtility.AbstractQueryKeyIterator

java.lang.Object
  wt.fc.collections.IteratorUtility.AbstractQueryKeyIterator

All Implemented Interfaces:

Iterator

Direct Known Subclasses:

ReferenceMap.QueryKeyIterator

Enclosing class:

IteratorUtility

abstract static class IteratorUtility.AbstractQueryKeyIterator

extends Object

implements Iterator

Iterates over a List of references, returning each reference's query key. If the reference doesn't have a query key, it is skipped. Subclasses define how the references are stored, what actions to take upon remove, and how to store the modcount

Subclasses should call peek() from their constructor once their references have been initialized.
