Determines whether all subsequent IDL attributes will be processed and placed in the generated .idl file.

Syntax

  
      [ emitidl([boolean],  
   defaultimports=[boolean]  
) ] ;

Parameters

boolean
Possible values: true, false, forced, restricted, push, or pop.

If true, any IDL category attributes encountered in a source code file will be placed in the generated .idl file. This is the default setting for emitidl.
If false, any IDL category attributes encountered in a source code file will not be placed in the generated .idl file.
If restricted, allows IDL attributes to be in the file without a module attribute. The compiler will not generate an .idl file.
If forced, overrides a subsequent restricted attribute, which requires a file to have a module attribute if there are IDL attributes in the file.
push lets you save the current emitidl settings to an internal emitidl stack, and pop lets you set emitidl to whatever value is at the top of the internal emitidl stack.

defaultimports =[ boolean] (optional)

If boolean is true, docobj.idl will be imported into the generated .idl file. Also, if an .idl file with the same name as an .h file that you #include into your source code is found in the same directory as the .h file, then the generated .idl file will contain an import statement for that .idl file.
If boolean is false, docobj.idl will not be imported into the generated .idl file. You will need to explicitly import .idl files with import.

Remarks

After the emitidl C++ attribute is encountered in a source code file, IDL category attributes will be placed in the generated .idl file. If there is no emitidl attribute, IDL attributes in the source code file will be output to the generated .idl file.

It is possible to have multiple emitidl attributes in a source code file. If [emitidl(false)]; is encountered in a file without a subsequent [emitidl(true)];, then no attributes will be processed into the generated .idl file.

Each time the compiler encounters a new file, emitidl is implicitly set to true.
