Deprecated. 
Method Detail

deepCopy

public RegExIterator 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

setRegexs

public static void setRegexs(IteratorSetting si,
                             String rowTerm,
                             String cfTerm,
                             String cqTerm,
                             String valueTerm,
                             boolean orFields)
Deprecated. 
Encode the terms to match against in the iterator

Parameters:
si - ScanIterator config to be updated
rowTerm - the pattern to match against the Key's row. Not used if null.
cfTerm - the pattern to match against the Key's column family. Not used if null.
cqTerm - the pattern to match against the Key's column qualifier. Not used if null.
valueTerm - the pattern to match against the Key's value. Not used if null.
orFields - if true, any of the non-null terms can match to return the entry
