Instance Method Detail

def []=(referent : Str, value : Model) #

Sets referent field of this box instance to value.

If referent is one of the typed fields (i.e., it was declared as a box parameter and thus has a type), a match against that type is performed.

def eqv?(other : MBoxInstance) #

Returns whether this box instance is equal to the other box instance.

This box instance and other box instance are equal if and only if their hashes are equal.


[View source]
def eqv?(other : MBox) #

Returns whether this box instance is parented by the other box.


[View source]
def field(name) #

Returns one of the fields in the namespace of this box instance.

Provides two other, model specific and prioritized properties: .name and .parent.
