Constructor Details

ArrayBindingSet

public ArrayBindingSet(String... names)

Creates a new Array-based BindingSet for the supplied bindings names. The supplied list of binding names is assumed to be constant; care should be taken that the contents of this array doesn't change after supplying it to this solution.

Parameters:

names - The binding names.

ArrayBindingSet

public ArrayBindingSet(BindingSet toCopy,
 Set<String> names,
 String[] namesArray)

ArrayBindingSet

public ArrayBindingSet(ArrayBindingSet toCopy,
 String... names)

Method Details

getDirectSetBinding

public BiConsumer<Value,ArrayBindingSet> getDirectSetBinding(String bindingName)

This is used to generate a direct setter into the array to put a binding value into. Can be used to avoid many comparisons to the bindingNames.

Parameters:

bindingName - for which you want the setter

Returns:

the setter biconsumer which can operate on any ArrayBindingSet but should only be used on ones with an identical bindingNames array. Otherwise returns null.

getDirectAddBinding

public BiConsumer<Value,ArrayBindingSet> getDirectAddBinding(String bindingName)

getDirectGetBinding

public Function<ArrayBindingSet,Binding> getDirectGetBinding(String bindingName)

getDirectGetValue

public Function<ArrayBindingSet,Value> getDirectGetValue(String bindingName)

getDirectHasBinding

public Function<ArrayBindingSet,Boolean> getDirectHasBinding(String bindingName)

getBindingNames

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 BindingSet

Specified by:

iterator in interface Iterable<Binding>

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.

getSortedBindingNames

public List<String> getSortedBindingNames()

addBinding

public void addBinding(Binding binding)

Description copied from interface: MutableBindingSet

Adds a binding to the binding set.

Specified by:

addBinding in interface MutableBindingSet

Parameters:

binding - The binding to add to the binding set.

setBinding

public void setBinding(Binding binding)

Specified by:

setBinding in interface MutableBindingSet

setBinding

public void setBinding(String name,
 Value value)

Specified by:

setBinding in interface MutableBindingSet

isEmpty

public boolean isEmpty()

Specified by:

isEmpty in interface BindingSet

addAll

public void addAll(ArrayBindingSet other)
