fourteen.eight.1 General
Types of properties range from the period of a set, how big is a beneficial font, new caption out of a windows, the name out-of a customers, and the like. Functions is actually an organic expansion off sphere-they are both titled members which have related products, therefore the sentence structure to own opening fields and you will functions is the same. Although not, in place of industries, features don’t denote shop cities. Rather, attributes provides accessors you to identify this new statements become executed whenever its philosophy is realize or written. Features ergo give a method for accompanying strategies toward training and you will creating off an enthusiastic object’s properties; in addition, it enable for example services as calculated.
A home_report range from a couple of features (§21) and you can a valid mixture of new five availability modifiers (§14.3.6), brand new (§14.step 3.5), fixed (§fourteen.7.2), digital (§14.6.cuatro, §fourteen.eight.6), override (§14.six.5, §fourteen www.datingranking.net/pl/sugar-daddy-for-me-recenzja/.7.6), sealed (§fourteen.6.6), conceptual (§fourteen.six.seven, §14.seven.6), and you can extern (§14.6.8) modifiers.
The sort of a home report specifies the sort of brand new possessions introduced because of the elizabeth (§fourteen.6.1) determine title of the property. Unless the house or property is a direct user interface affiliate implementation, the latest member_name is only a keen identifier. For an explicit user interface affiliate execution (§17.six.2), the new associate_name include a program_type followed by a great ” . ” and you may an enthusiastic identifier.

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.
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.
A house_initializer may only be provided with getting an automatically followed possessions (§14.seven.4), and causes brand new initialization of your own hidden arena of instance qualities into worthy of given by the term.
Even though the syntax for being able to access property is similar just like the you to definitely for an industry, property isn’t classified as a variable. Hence, this is simply not you can to pass a home since the a good ref otherwise out argument.
When a property declaration boasts an extern modifier, the house is considered are an outward property. As an external assets statement brings not any execution, every one of their accessor_declarations contains an effective semicolon.
fourteen.seven.dos Fixed and you will instance qualities
When property report comes with a fixed modifier, the property is claimed to-be a static possessions. When zero fixed modifier can be acquired, the house is said getting a case assets.
A fixed home is maybe not on the a specific such, and is a harvest-go out error to mention to this regarding the accessors out-of a static property.
A situation property is of this a given instance of good group, and this instance are going to be utilized because this (§11.eight.12) on the accessors of this assets.
