## 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.
  Since:
    5.2.0

    Modifier and Type | Method and Description

    `boolean` | `isBound()` Determines if the parameter is actually bound.
    `void` | `reset()` Resets the conduit, clearing any temporarily cached data (from a non-invariant `Binding`).
