All Methods Instance Methods Concrete Methods Modifier and Type Method Description
deepCopy(IteratorEnvironment env)Creates a deep copy of this iterator as though seek had not yet been called.
describeOptions()Gets an iterator options object that contains information needed to configure this iterator.
getTopValue()Returns top value.
validateOptions(Map<String,String> options)Check to see if an options map contains all options required by an iterator and that the option values are in the expected formats.

public SortedKeyValueIterator<Key,Value> deepCopy(IteratorEnvironment env)Description copied from interface:
SortedKeyValueIteratorCreates a deep copy of this iterator as though seek had not yet been called. init should be called on an iterator before deepCopy is called. init should not need to be called on the copy that is returned by deepCopy; that is, when necessary init should be called in the deepCopy method on the iterator it returns. The behavior is unspecified if init is called after deepCopy either on the original or the copy. A proper implementation would call deepCopy on the source.
public Value getTopValue()Description copied from interface:
SortedKeyValueIteratorReturns top value. Can be called 0 or more times without affecting behavior of next() or hasTop().
For performance reasons, iterators reserve the right to reuse objects returned by
SortedKeyValueIterator.next()is called, changing the underlying data that the object references. Iterators that need to save an object returned by
getTopValueought to copy the object's data into a new object in order to avoid aliasing bugs.
public OptionDescriber.IteratorOptions describeOptions()Description copied from interface:
OptionDescriberGets an iterator options object that contains information needed to configure this iterator. This object will be used by the accumulo shell to prompt the user to input the appropriate information.
