Arguments
| Attributes | An optional list of one or more attributes that describe meta information for am entity, such as for example the [TestMethod] attribute on a method/function containing tests in a MsTest class library. Please note that Attributes must be on the same line or suffixed with a semi colon when they are written on the line above that keyword. |
| <idName> | A valid identifier name for the event that you are defining. Like other methods, events are entities. Event names must be unique within a class, but can share the same name as other entities in your application. |
| AS <idType> | Specifies the data type. If omitted, then depending on the compiler options the type will be either USUAL or determined by the compiler. |
| <Expression> | Expression that implements the accessor |
| => <Expression> | Single expression that replaces the multiline body for the entity. CANNOT be compiled with a body |
| <Body> | Program statements that form the code of this entity. The <Body> can contain one or more RETURN statements to return control to the calling routine and to serve as the function return value. If no return statement is specified, control passes back to the calling routine when the function definition ends, and the function will return a default value depending on the return value data type specified (NIL if the return value is not strongly typed). CANNOT be combined with an Expression Body |
Description
There are 3 types of event declarations:
•Single line declaration without ADD / REMOVE accessors
•Single line declaration with ADD / REMOVE accessors
•Multi line declaration with ADD accessor block and/or REMOVE accessor bock
