```
public boolean next()
             throws LiteCoreException
```
    Throws:

public long getRowCount()
                 throws LiteCoreException

  - refresh

@Nullable
public C4QueryEnumerator refresh()
                          throws LiteCoreException
```
    Throws:
    
    LiteCoreException
  - getColumns
```
@NonNull
public FLArrayIterator getColumns()
```
    FLArrayIterator columns The columns of this result, in the same order as in the query's `WHAT` clause. NOTE: FLArrayIterator is member variable of C4QueryEnumerator. Not necessary to release.
  - getMissingColumns
```
public long getMissingColumns()
```
    Returns a bitmap in which a 1 bit represents a column whose value is MISSING. This is how you tell a missing property value from a value that is JSON 'null', since the value in the `columns` array will be a Fleece `null` either way.
  - copy
```
@NonNull
public C4QueryEnumerator copy()
```
    Returns a new Java instance referring to the same underlying C object.
    
    Returns:
    
    the Java-level copy
  - close
```
@CallSuper
public void close()
```
  - seek
```
public boolean seek(long rowIndex)
             throws LiteCoreException
```
    Throws:
    
    LiteCoreException
