Constructor Detail

ArrayForm

public ArrayForm(Class<?> type,
                 Form<?> form)

Parameters:

type - the Class to which elements of the desired arrays belong

form - the desired Form that transforms instances of type

Method Detail

unit

public Object unit()

Description copied from class: Form

Returns a default–possibly null–value of type T. Used as the fallback return value when coercing an invalid structural value.

Overrides:

unit in class Form<Object>

type

public Class<?> type()

Description copied from class: Form

Returns the reified Class of type T.

Specified by:

type in class Form<Object>

mold

public Item mold(Object array,
                 Item item)

Description copied from class: Form

Converts a nominally typed Java object into its structurally typed equivalent based on the provided prototype item. The passed-in item is assumed to be non-null. The returned Item must never be null.

Overrides:

mold in class Form<Object>

mold

public Item mold(Object array)

Description copied from class: Form

Converts a nominally typed Java object into its structurally typed equivalent. The returned Item must never be null.

Specified by:

mold in class Form<Object>

cast

public Object cast(Item item)

Description copied from class: Form

Converts a structurally typed item into a nominally typed Java object. The passed-in item is assumed to be non-null.

Specified by:

cast in class Form<Object>
