    Constructor.
    
    Parameters:
    
    querySeq - sequence providing cone search query parameters
    
    coneSearcher - cone search implementation
    
    errAct - defines action on cone search invocation error
    
    coverage - coverage for results, or null
    
    bestOnly - whether all results or just best are required
    
    distFilter - true to perform post-query filtering on results based on the distance between the query position and the result row position
    
    distanceCol - name of column to hold distance information in output table, or null

public uk.ac.starlink.table.StarTable getConeResult()
                                             throws java.io.IOException
```
    Description copied from interface: ConeResultRowSequence
    
    Returns the result of the cone search for the current row of this sequence. The work will typically be done using ConeMatcher.getConeResult(uk.ac.starlink.ttools.cone.ConeSearcher, uk.ac.starlink.ttools.cone.ConeErrorPolicy, boolean, boolean, java.lang.String, double, double, double).
    If no records in the cone are found, the return value may either be null or (preferably) an empty table with the correct columns.
    
    Specified by:
    
    getConeResult in interface ConeResultRowSequence
    
    Returns:
    
    table giving rows strictly within the match criteria for the current row of this cone query sequence, or null
    
    Throws:
    
    java.io.IOException

    Throws:
    
    java.io.IOException
  - close
```
public void close()
           throws java.io.IOException
```
    Specified by:
    
    close in interface uk.ac.starlink.table.RowSequence
    
    Throws:
    
    java.io.IOException
  - getDec
```
public double getDec()
              throws java.io.IOException
```
    Description copied from interface: ConeQueryRowSequence
    
    Get central declination for the current row's cone search request in degrees.
    
    Specified by:
    
    getDec in interface ConeQueryRowSequence
    
    Returns:
    
    declination
    
    Throws:
    
    java.io.IOException
  - getRa
```
public double getRa()
             throws java.io.IOException
```
    Description copied from interface: ConeQueryRowSequence
    
    Get central right ascension for the current row's cone search request in degrees.
    
    Specified by:
    
    getRa in interface ConeQueryRowSequence
    
    Returns:
    
    right ascension
    
    Throws:

  - getRadius
```
public double getRadius()
                 throws java.io.IOException
```
    Description copied from interface: ConeQueryRowSequence
    
    Get search radius for the current row's cone search request in degrees.
    
    Specified by:

  - getIndex
```
public long getIndex()
              throws java.io.IOException
```
    Description copied from interface: ConeQueryRowSequence
    
    Get the index in the underlying table to which the current row relates. The identity of this underlying table is not specified by this interface, but must be understood by the creator and user of instances. In particular, the return value does not necessarily increment by one for each call to next.
    
    Specified by:
    
    getIndex in interface ConeQueryRowSequence
    
    Returns:
    
    row index
