Interface ParameterConduit

All Superinterfaces:
FieldConduit<Object>

public interface ParameterConduit extends FieldConduit<Object>
A facade around Binding and InternalComponentResources that is used to instrument fields with the Parameter annotation. Extends FieldConduit so that the get() method implicitly coerces the value to the field's type. FieldConduit.get(Object, org.apache.tapestry5.plastic.InstanceContext) will read from the underlying Binding and used the TypeCoercer coerce the value to the parameter field's type. get() also includes a null value check (as per Parameter.allowNull(). FieldConduit.set(Object, org.apache.tapestry5.plastic.InstanceContext, Object) pushes the value into the binding.
