Define DataBinding objects

A DataBinding. is the abstraction of an evaluable expression which might be executed in a BindingEvaluationContext.

A DataBinding is defined in the context of a Bindable., which is the owner of DataBinding (remember that Bindable references both a BindingFactory and a BindingModel)

A DataBinding might be created using this constructor:

public DataBinding(String unparsed, Bindable owner, Type declaredType, BindingDefinitionType bdType);

For example:

Bindable myBindable = ...; // myBindable should be somewhere initialized
DataBinding<String> myBinding = new DataBinding<String>("person.name",myBindable,String.class,BindingDefinitionType.GET_SET);

Initialize a DataBinding:

• whose owner is the myBindable variable (a Bindable instance)

• where declared type (type of expression defined by the binding) is String

• where binding is executable both as readable and settable

• where expression is set to person.name

  To be valid, myBindable variable should define:

• a BindingModel declaring a BindingVariable called 'person' (suppose that type of this variable is reflected by Person Java class)

• a suitable BindingFactory allowing to browse 'name' from a Person type (this might be implemented by Person Java class if this class defines both getName() and setName(String) methods, and if JavaBindingFactory is used)

  Validity of a DataBinding might be tested using isValid() method.
