Public Property MustImplement As Boolean

Property Value

A Boolean that is true if the method is declared abstract and thus requires an implementation; otherwise, false.

Remarks

MustImplement returns or sets whether the method is implemented or requires an implementation in subclasses. Note that for some languages this might always be false, and that setting MustImplement might fail, depending on the language.
