14.seven.1 General
Types of properties through the amount of a set, the size of an effective font, the caption regarding a window, title regarding a consumer, and so on. Functions are a natural expansion out-of fields-they are both called players having relevant sizes, and the syntax getting opening fields and you will qualities is similar. Although not, unlike industries, attributes do not denote shops towns and cities. As an alternative, services has actually accessors one establish the brand new statements as done whenever its viewpoints was discover otherwise written. Properties for this reason render an apparatus getting associating steps with the reading and you may writing regarding an object’s services; also, they enable particularly attributes to get calculated.
A home_report start around a couple of qualities (§21) and you will a valid mix of brand new four access modifiers (§fourteen.3.6), new (§fourteen.3.5), static (§14.eight.2), virtual (§14.six.cuatro, §fourteen.eight.6), override (§14.six.5, §14.seven.6), closed (§14.six.6), conceptual (§fourteen.six.7, §14.seven.6), and you may extern (§fourteen.six.8) modifiers.
The kind of property report determine the sort of the latest assets lead because of the elizabeth (§fourteen.six.1) determine the name of the property. Until the house or property try an explicit program representative execution, the newest user_name’s just a keen identifier. Getting a specific interface user implementation (§17.six.2), new affiliate_term includes a program_types of with an excellent ” . ” and you may an identifier.
A property_body may either consist of an accessor body or an expression body. In an accessor body, accessor_declarations, which shall be enclosed in ” < ">” tokens, declare the accessors (§14.7.3) of the property. The accessors specify the executable statements associated with reading and writing the property ourtime.
An expression body consisting of => followed by an expression E and a semicolon is exactly equivalent to the statement body < get>> , and can therefore only be used to specify getter-only properties where the result of the getter is given by a single expression.
Property_initializer might only get for an instantly adopted property (§14.7.4), and causes brand new initialization of underlying arena of such as features toward really worth provided by the term.
As the syntax to possess opening property is similar because that to have an area, a house isn’t categorized while the a changeable. Therefore, this is simply not you can easily to take and pass property because the good ref or aside argument.
Whenever a property declaration comes with an enthusiastic extern modifier, the house or property is said as an external property. Since the an outward property statement provides no actual execution, all of the accessor_declarations includes good semicolon.
14.eight.dos Fixed and you may eg properties
When property declaration comes with a fixed modifier, the home is said to-be a fixed possessions. Whenever no static modifier can be found, the home is alleged to be a situation possessions.
A fixed property is not of a particular instance, and it is a collect-big date mistake to refer to that about accessors regarding a great fixed property.
A situation house is from the a given illustration of a beneficial group, hence such as for instance are accessed since this (§11.seven.12) in the accessors of these property.
