`Constructor` Statement

Initializes the data of a new instance of an object.

Syntax

[ @Deprecated ] _
Constructor [ parameter_list ]
    [ statements ]
End [ Constructor ]

Parts

@Deprecated: Optional modifier shows a warning if a person tries to use the given constructor. This lets you remove the constructor in a subsequent release. See @Deprecated for more information.
parameter_list: Optional, one or more variable declarations with a comma between each. Parentheses (( )) around the parameters are optional unless you use @Option to make them mandatory. See Parameter List for more information.; Usually the variable is local to the constructor. But if you put Self and a dot (.) befor the name, the parameter refers to the member of the parent construct with that name. The parameter cannot include type information, for example, As or In. But the parameter can be ByRef and/or Optional, and can have a default value.
statements: Optional statements.
End: Completes the statement. You can also use End Constructor.; You can change the syntax of this part. See @Option Directive for more information.

Instructions

ViviFire lets you have many constructors in an object. Each constructor must have a different parameter signature. A constructor without parameters is known as a default constructor.

All constructors must be in a group together. They come after a possible data section and before a possible destructor or other procedures.

You can think of the data section as a type of constructor. Statements you put in this section always run before a constructor gets called.

@Option End Block and @Option End

See @Option Directive for more information.
