BEGIN_METHOD

#define BEGIN_METHOD ( name , arguments ) ...

Begins the implementation of a method.

name is the name of the function, as specified in the class declaration.
arguments describes the arguments of the method.

Be careful ! As the implementation function will receive its arguments as a pointer at the interpreter stack, arguments is in fact the inside of a structure describing the stack contents.

Consequently :

Each argument must be a GB_XXXX structure of the GB_VALUE family.
The arguments are separated by semicolons, and NOT commas.

The Gambas datatypes can be :

Gambas datatype	Signature pattern	Corresponding structure
`Boolean`	`"b"`	`GB_BOOLEAN`
`Integer`	`"i"`	`GB_INTEGER`
`Float`	`"f"`	`GB_FLOAT`
`String`	`"s"`	`GB_STRING`
`Date`	`"d"`	`GB_DATE`
`Object`	`"o"`	`GB_OBJECT`
`Variant`	`"v"`	`GB_VARIANT`
a class named `Abc`	`"Abc"`	`GB_OBJECT`

Example :

A method named foo declared this way :

  ...
  GB_METHOD("foo", NULL, "iisvbInteger[];d", do_foo),
  ...

will be implemented this way :

  BEGIN_METHOD(do_foo,
    GB_INTEGER param1;
    GB_INTEGER param2;
    GB_STRING param3;
    GB_VARIANT param4;
    GB_BOOLEAN param5;
    GB_OBJECT param6;
    GB_DATE param7)

  ...

  END_METHOD

Note that semicolons delimitate arguments, and that the last argument has no semicolon at its end.
