ListBindingSet

public ListBindingSet(List<String> names,
 Value... values)

Creates a new List-based BindingSet containing the supplied bindings. 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. The number of supplied values must be equal to the number of the binding names.

Parameters:

names - The binding names.

values - The binding values.

ListBindingSet

public ListBindingSet(List<String> bindingNames,
 List<? extends Value> values)

Creates a new List-based BindingSet containing the supplied bindings. The supplied lists are assumed to be constant; care should be taken that the contents of these lists don't change after supplying them to this solution. The number of supplied values must be equal to the number of the binding names.

Parameters:

bindingNames - The binding names.

values - The binding values.

Method Details

getBindingNames

public Set<String> getBindingNames()

Description copied from interface: BindingSet

Gets the names of the bindings in this 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.

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.

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.

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.

size

public int size()

Description copied from interface: BindingSet

Returns the number of bindings in this BindingSet.

Returns:

The number of bindings in this BindingSet.
