NoLabelIterator
public NoLabelIterator()
- Deprecated.
deepCopy
public NoLabelIterator deepCopy(IteratorEnvironment env)
- Deprecated.
- Description copied from interface:
SortedKeyValueIterator
- Creates 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.
- Specified by:
deepCopy
in interface SortedKeyValueIterator<Key,Value>
- Overrides:
deepCopy
in class WrappingIterator
- Parameters:
env
- IteratorEnvironment environment in which iterator is being run.
- Returns:
- SortedKeyValueIterator a copy of this iterator (with the same source and settings).
consume
protected void consume()
throws IOException
- Deprecated.
- Specified by:
consume
in class SkippingIterator
- Throws:
IOException
init
public void init(SortedKeyValueIterator<Key,Value> source,
Map<String,String> options,
IteratorEnvironment env)
throws IOException
- Deprecated.
- Description copied from interface:
SortedKeyValueIterator
- Initializes the iterator. Data should not be read from the source in this method.
- Specified by:
init
in interface SortedKeyValueIterator<Key,Value>
- Overrides:
init
in class WrappingIterator
- Parameters:
source
- SortedKeyValueIterator source to read data from.options
- Map map of string option names to option values.env
- IteratorEnvironment environment in which iterator is being run.
- Throws:
IOException
- unused.
describeOptions
public OptionDescriber.IteratorOptions describeOptions()
- Deprecated.
- Description copied from interface:
OptionDescriber
- Gets 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.
- Specified by:
describeOptions
in interface OptionDescriber
- Returns:
- an iterator options object
validateOptions
public boolean validateOptions(Map<String,String> options)
- Deprecated.
- Description copied from interface:
OptionDescriber
- Check to see if an options map contains all options required by an iterator and that the option values are in the expected formats.
- Specified by:
validateOptions
in interface OptionDescriber
- Parameters:
options
- a map of option names to option values
- Returns:
- true if options are valid, false otherwise
