Method Details

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.

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.

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.

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.

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.

mapBinding

private Binding mapBinding(Binding binding)
