public class SPARQLQueryBindingSet extends AbstractBindingSet
An implementation of theBindingSetinterface that is used to evaluate query object models. This implementations differs fromMapBindingSetin 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 ofQueryBindingSet, and is only included here to avoid a circular dependency between the algebra-evaluation module and the sparql-repository module.- See Also:

Method Detail

addAll
public void addAll(BindingSet bindingSet)
-
addBinding
public void addBinding(Binding binding)
Adds a new binding to the binding set. The binding's name must not already be part of this binding set.- Parameters:
binding- The binding to add this this BindingSet.
-
addBinding
public void addBinding(String name, Value value)
Adds a new binding to the binding set. The binding's name must not already be part of this binding set.- Parameters:
name- The binding's name, must not be bound in this binding set already.value- The binding's value.
-
setBinding
public void setBinding(Binding binding)
-
removeBinding
public void removeBinding(String name)
-
removeAll
public void removeAll(Collection<String> bindingNames)
-
retainAll
public void retainAll(Collection<String> bindingNames)
-
getBindingNames
public Set<String> getBindingNames()
Description copied from interface:BindingSetGets the names of the bindings in this BindingSet.- Returns:
- A set of binding names.
-
getValue
public Value getValue(String bindingName)
Description copied from interface:BindingSetGets the value of the binding with the specified name from this 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:BindingSetGets the binding with the specified name from this 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:BindingSetChecks whether this BindingSet has a binding with the specified name.- 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:BindingSetCreates 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.
-
size
public int size()
Description copied from interface:BindingSetReturns the number of bindings in this BindingSet.- Returns:
- The number of bindings in this BindingSet.
-
equals
public boolean equals(Object other)
Description copied from interface:BindingSetCompares a BindingSet object to another object.- Specified by:
equalsin interfaceBindingSet- Overrides:
equalsin classAbstractBindingSet- Parameters:
other- The object to compare this binding to.- Returns:
- true if the other object is an instance of
BindingSetand it contains the same set of bindings (disregarding order), false otherwise.
