MutableTupleQueryResult (OpenRDF Sesame 2.7.13 API)

java.lang.Object
- org.openrdf.query.impl.MutableTupleQueryResult

All Implemented Interfaces:

CloseableIteration<BindingSet,QueryEvaluationException>, Iteration<BindingSet,QueryEvaluationException>, Cloneable, QueryResult<BindingSet>, TupleQueryResult
```
public class MutableTupleQueryResult
extends Object
implements TupleQueryResult, Cloneable
```
An implementation of the TupleQueryResult interface that stores the complete query result in memory. The query results in a MutableTupleQueryResult can be iterated over multiple times and can also be iterated over in reverse order.

```
public MutableTupleQueryResult(Collection<String> bindingNames,
                               Collection<? extends BindingSet> bindingSets)
```
    Creates a query result table with the supplied binding names. The supplied list of binding names is assumed to be constant; care should be taken that the contents of this list doesn't change after supplying it to this solution.
    
    Parameters:
    
    bindingNames - The binding names, in order of projection.
  - MutableTupleQueryResult
```
public MutableTupleQueryResult(Collection<String> bindingNames,
                               Iteration<? extends BindingSet,E> bindingSetIter)
                        throws E extends Exception
```
    Throws:
    
    E extends Exception

public MutableTupleQueryResult(TupleQueryResult tqr)

```
    Throws:
    
    QueryEvaluationException
- Method Detail
  - getBindingNames
```
public List<String> getBindingNames()
```
    Description copied from interface: TupleQueryResult
    
    Gets the names of the bindings, in order of projection.
    
    Specified by:
    
    getBindingNames in interface TupleQueryResult
    
    Returns:
    
    The binding names, in order of projection.
  - size
```
public int size()
```
  - get
```
public BindingSet get(int index)
```
  - getIndex
```
public int getIndex()
```
  - setIndex
```
public void setIndex(int index)
```
  - hasNext
```
public boolean hasNext()
```
    Description copied from interface: Iteration
    
    Returns true if the iteration has more elements. (In other words, returns true if Iteration.next() would return an element rather than throwing a NoSuchElementException.)
    
    Specified by:
    
    hasNext in interface Iteration<BindingSet,QueryEvaluationException>
    
    Returns:
    
    true if the iteration has more elements.
  - next
```
public BindingSet next()
```
    Description copied from interface: Iteration
    
    Returns the next element in the iteration.
    
    Specified by:
    
    next in interface Iteration<BindingSet,QueryEvaluationException>
    
    Returns:
    
    the next element in the iteration.
  - hasPrevious
```
public boolean hasPrevious()
```
  - previous
```
public BindingSet previous()
```
  - beforeFirst
```
public void beforeFirst()
```
    Moves the cursor to the start of the query result, just before the first binding set. After calling this method, the result can be iterated over from scratch.
  - afterLast
```
public void afterLast()
```
    Moves the cursor to the end of the query result, just after the last binding set.
  - insert
```
public void insert(BindingSet bindingSet)
```
    Inserts the specified binding set into the list. The binding set is inserted immediately before the next element that would be returned by next(), if any, and after the next element that would be returned by previous(), if any. (If the table contains no binding sets, the new element becomes the sole element on the table.) The new element is inserted before the implicit cursor: a subsequent call to next() would be unaffected, and a subsequent call to previous() would return the new binding set.
    
    Parameters:
    
    bindingSet - The binding set to insert.
  - insert
```
public void insert(int index,
                   BindingSet bindingSet)
```
  - append
```
public void append(BindingSet bindingSet)
```
  - set
```
public void set(BindingSet bindingSet)
```
  - set
```
public BindingSet set(int index,
                      BindingSet bindingSet)
```
  - remove
```
public void remove()
```
    Description copied from interface: Iteration
    
    Removes from the underlying collection the last element returned by the iteration (optional operation). This method can be called only once per call to next.
    
    Specified by:
    
    remove in interface Iteration<BindingSet,QueryEvaluationException>
  - remove
```
public BindingSet remove(int index)
```
  - clear
```
public void clear()
```
  - close
```
public void close()
```
    Description copied from interface: CloseableIteration
    
    Closes this iteration, freeing any resources that it is holding. If the iteration has already been closed then invoking this method has no effect.
    
    Specified by:
    
    close in interface CloseableIteration<BindingSet,QueryEvaluationException>
  - clone
```
public MutableTupleQueryResult clone()
                              throws CloneNotSupportedException
```
    Overrides:
    
    clone in class Object
    
    Throws:
    
    CloneNotSupportedException
