public class QueryBindingSet extends AbstractBindingSet implements MutableBindingSet
An implementation of theBindingSetinterface that is used to evalate query object models. This implementations differs fromMapBindingSetin that it maps variable names to Value objects and that the Binding objects are created lazily.- See Also:

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.- Specified by:
addBindingin interfaceMutableBindingSet- 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.- Specified by:
addBindingin interfaceMutableBindingSet- 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)
- Specified by:
setBindingin interfaceMutableBindingSet
-
setBinding
public void setBinding(String name, Value value)
- Specified by:
setBindingin interfaceMutableBindingSet
-
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.- Specified by:
getBindingNamesin interfaceBindingSet- 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.- Specified by:
getValuein interfaceBindingSet- 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.- Specified by:
getBindingin interfaceBindingSet- 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.- Specified by:
hasBindingin interfaceBindingSet- 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.- Specified by:
iteratorin interfaceBindingSet- Specified by:
iteratorin interfaceIterable<Binding>
-
size
public int size()
Description copied from interface:BindingSetReturns the number of bindings in this BindingSet.- Specified by:
sizein interfaceBindingSet- 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.
