Method Details

next

public abstract TensorForm<V> next()

fromArray

public abstract T fromArray(Object... array)

toArray

public abstract Object[] toArray(T tensor)

newArray

protected Object[] newArray(int length)

tag

public String tag()

Description copied from class: Form

Returns the key of the tag attribute that distinguishes structures of this Form; returns null if this Form has no distinguishing tag attribute. Used to accelerate distrcrimination of polymorphic structural types with nominal type hints.

Overrides:

tag in class Form<T>

mold

public Item mold(T tensor)

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<T>

cast

public T 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<T>
