Accessibility so it modifier suppress a good derived classification off further overriding the house. New accessors out of a closed property are also sealed.

Except for differences in statement and you can invocation syntax, digital, sealed, bypass, and abstract accessors function the same as virtual, close, bypass and you may abstract tips. Especially, the rules explained in §14.six.4, §14.6.5, §14.six.6, and you will §14.6.7 use because if accessors was in fact ways of a matching setting:

• A get accessor corresponds to good parameterless approach with a profit value of the home particular as well as the exact same modifiers as that features possessions.
• A-flat accessor represents a strategy which have one value factor of the house type, an emptiness get back sort of, as well as the exact same modifiers while the with which has possessions.

X was a virtual realize-only assets, Y is a virtual understand-write possessions, and you may Z try an abstract see-build property. Because Z try conceptual, the newest which includes category A should additionally be declared conceptual.

Here, the brand new declarations from X , Y , and Z is actually overriding assets declarations. For every property report precisely matches the new the means to access modifiers, types of, and you can term of your own involved inherited assets. The rating accessor from X and the set accessor of Y make use of the base search term to view the fresh passed on accessors. New statement out-of Z overrides both conceptual accessors-ergo, there aren’t any the abstract means players inside the B , and you can B is actually permitted to be a non-conceptual classification. avoid example

When property are proclaimed because the an bypass, any overridden accessors is accessible to brand new overriding password. Additionally, the newest stated the means to access from both property otherwise indexer in itself, as well as brand new accessors, will fits regarding the latest overridden affiliate and you will accessors.

14.8.1 General

senior sizzle

A conference try a part that enables an object otherwise group to add announcements. Members can be mount executable password to have occurrences by the providing feel handlers.

An event_declaration start around a collection of attributes (§21) and you can a legitimate mix of the five accessibility modifiers (§14.step 3.6), the fresh new (§14.3.5), static (§14.6.step 3, §fourteen.8.4), virtual (§fourteen.six.4, §14.8.5), override (§fourteen.6.5, §fourteen.8.5), close (§14.6.6), abstract (§14.6.7, §fourteen.8.5), and extern (§fourteen.6.8) modifiers.

The kind of an event declaration can be good outsource_kind of (§8.2.8), which subcontract_kind of are at the least given that accessible just like the knowledge itself (§7.5.5).

14.8 Incidents

A meeting report range from experience_accessor_declarations. However, whether or not it doesn’t, to have non-extern, non-abstract occurrences, the compiler will also provide him or her automatically (§fourteen.8.2); for extern events, the brand new accessors are offered on the outside.

An event declaration one omits feel_accessor_declarations defines no less than one occurrences-you to for each of one’s varying_declarators. The fresh attributes and you can modifiers apply to all players stated of the such as for example an event_declaration.

Whenever a conference declaration has an enthusiastic extern modifier, case is considered is an external event. Because the an outward skills report will bring no implementation, it is an error for it to add both the extern modifier and you will feel_accessor_declarations.

It is a collect-date error for a varying_declarator away from an event statement with a conceptual otherwise exterior modifier to add an adjustable_initializer.

A meeting can be utilized because remaining-hands operand of your += and you can -= operators. Such operators are used, respectively, to connect feel handlers in order to, or even reduce enjoy handlers of a conference, while the availableness modifiers of enjoy manage the latest contexts in the which for example operations are allowed.

Truly the only surgery that will be allowed into a conference because of the code that’s away from input and that you to experiences try stated, was += and you will -= . Therefore, if you are like password will add and remove handlers getting a conference, it can’t actually receive or customize the underlying list of skills handlers.

From inside the an operation of your mode x += y or x –= y , whenever x is actually a conference caused by the newest process possess particular gap (§.4) (in place of obtaining the kind of x , on property value x adopting the project, for almost every other this new += and you can -= workers laid out on low-event designs). So it suppresses outside code regarding indirectly examining the fundamental subcontract regarding a meeting.
