Instance Method Detail
Sets this model's referent item (whatever the meaning of that is) to value.
Models may choose to override this method.
Returns nil if found no referent item (this is the default meaning; it may be changed by the overriding model).
Returns index-th item of this model.
Subclasses should rather override this method instead
of #nth.
Returns a subset of items in this model.
Subclasses should rather override this method instead
of #nth.
Returns whether this model is equal-by-value to the other model.
Returns a field's value for this model, or nil if this model has no such field.
Returns whether this model is of the type other, or is equal-by-value to other.
Returns the index-th item of this model,
Subclasses should not generally override this method.
They should override #[]? instead.
Raises ModelCastException if index is improper.
Returns a subset of items in this model.
Subclasses should not generally override this method.
They should override #[]? instead.
Raises ModelCastException if index is improper.
Returns a subset of items in this model.
Subclasses should not generally override this method.
They should override #[]? instead.
Raises ModelCastException if index is improper.
Sets this model's referent item (whatever the meaning of that is) to value.
Generally, subclasses should not choose to override
this method. They can override #[]= instead.
Converts (casts) this model into an MBool. Inverts
this MBool (applies not) if inverse is true.
