InterfaceType

Is this type equivalent to other.

Note that plain == will distinguish types from type aliases, which is typically not desirable, so =:= is usually the most appropriate comparison operator.

Is this type a leaf type?

true if after stripping of aliases the underlying type a scalar or an enum, false otherwise.

Is the underlying of this type a leaf type?

Strip off all aliases, nullability and enclosing list types until an underlying leaf type is reached, in which case yield true, or an a object, interface or union type which is reached, in which case yield false.

The element type of this type.

If this type is is a list, yield the non-list underlying type. Otherwise yield None.

A non-nullable version of this type.

If this type is nullable, yield the non-nullable underlying type. Otherwise yield this type.

Does the path fns from this type specify multiple values.

true if navigating through the path fns from this type might specify 0 or more values. This will be the case if the path passes through at least one field of a List type.

Does the path fns from this type specify a nullable type.

true if navigating through the path fns from this type might specify an optional value. This will be the case if the path passes through at least one field of a nullable type.

Returns a string representation of the object.

The default representation is platform dependent.

Yield the type of the field named fieldName of the object type underlying this type.

Strip off all aliases, nullability and enclosing list types until an underlying object type is reached which has a field named fieldName, in which case yield the type of that field; if there is no such field, yields None.

Yield the leaf type underlying this type.

Strip off all aliases, nullability and enclosing list types until an underlying leaf type is reached, in which case yield it, or an a object, interface or union type which is reached, in which case yield None.

Yield the named type underlying this type.

Strips of nullability and enclosing list types until an underlying named type is reached. This method will always yield a named type.

Yield the object type underlying this type.

Strip off all aliases, nullability and enclosing list types until an underlying object type is reached, in which case yield it, or a non-object type which isn't further reducible is reached, in which case yield None.
