SPARQLQueryBindingSet (OpenRDF Sesame 2.7.13 API)

java.lang.Object
- org.openrdf.repository.sparql.query.SPARQLQueryBindingSet

All Implemented Interfaces:

Serializable, Iterable<Binding>, BindingSet
```
public class SPARQLQueryBindingSet
extends Object
implements BindingSet
```
An implementation of the BindingSet interface that is used to evalate query object models. This implementations differs from MapBindingSet in that it maps variable names to Value objects and that the Binding objects are created lazily. Note that this class is a fully equivalent copy of QueryBindingSet, and is only included here to avoid a circular dependency between the algebra-evaluation module and the sparql-repository module.

public Set<String> getBindingNames()
```
    Description copied from interface: BindingSet
    
    Gets the names of the bindings in this BindingSet.
    
    Specified by:
    
    getBindingNames in interface BindingSet
    
    Returns:
    
    A set of binding names.
  - getValue
```
public Value getValue(String bindingName)
```
    Description copied from interface: BindingSet
    
    Gets the value of the binding with the specified name from this BindingSet.
    
    Specified by:
    
    getValue in interface BindingSet
    
    Parameters:
    
    bindingName - The name of the binding.
    
    Returns:
    
    The value of the binding with the specified name, or null if there is no such binding in this BindingSet.
  - getBinding
```
public Binding getBinding(String bindingName)
```
    Description copied from interface: BindingSet
    
    Gets the binding with the specified name from this BindingSet.
    
    Specified by:
    
    getBinding in interface BindingSet
    
    Parameters:
    
    bindingName - The name of the binding.
    
    Returns:
    
    The binding with the specified name, or null if there is no such binding in this BindingSet.
  - hasBinding
```
public boolean hasBinding(String bindingName)
```
    Description copied from interface: BindingSet
    
    Checks whether this BindingSet has a binding with the specified name.
    
    Specified by:
    
    hasBinding in interface BindingSet
    
    Parameters:
    
    bindingName - The name of the binding.
    
    Returns:
    
    true if this BindingSet has a binding with the specified name, false otherwise.
  - iterator
```
public Iterator<Binding> iterator()
```
    Description copied from interface: BindingSet
    
    Creates an iterator over the bindings in this BindingSet. This only returns bindings with non-null values. An implementation is free to return the bindings in arbitrary order.
    
    Specified by:
    
    iterator in interface Iterable<Binding>
    
    Specified by:
    
    iterator in interface BindingSet
  - size
```
public int size()
```
    Description copied from interface: BindingSet
    
    Returns the number of bindings in this BindingSet.
    
    Specified by:
    
    size in interface BindingSet
    
    Returns:
    
    The number of bindings in this BindingSet.
  - equals
```
public boolean equals(Object other)
```
    Description copied from interface: BindingSet
    
    Compares a BindingSet object to another object.
    
    Specified by:
    
    equals in interface BindingSet
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    other - The object to compare this binding to.
    
    Returns:
    
    true if the other object is an instance of BindingSet and it contains the same set of bindings (disregarding order), false otherwise.
  - hashCode
```
public int hashCode()
```
    Description copied from interface: BindingSet
    The hash code of a binding is defined as the bit-wise XOR of the hash codes of its bindings:
```
 int hashCode = 0;
 for (Binding binding : this) {
        hashCode ˆ= binding.hashCode();
 }
 
```
    Note: the calculated hash code intentionally does not dependent on the order in which the bindings are iterated over.
    Specified by:
    
    hashCode in interface BindingSet
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    A hash code for the BindingSet.

```
    Overrides:
    
    toString in class Object
