CHAPTER 7: Integrating External Libraries ExternalObject object 201

automatically defined, and you can access the properties and methods through an instance of that

class. For example:

anotherlib= new ExternalObject ("lib:" + filespec); // load the library

alert(anotherlib.version) ;

// instantiate library-defined class

var myObject = new MyNewClass() ;

// access functions from instance

var a = myObject.method_abc(1,2.0,true,"this is data") ;

alert(a) ;

anotherlib.unload() ;

For details of how to define functions for direct access through the ExternalObject object, see

“

Defining entry points for indirect access” on page 206.

ExternalObject object

You specify the name of the library in the constructor. The constructor searches for the named library

using the paths defined in the static property

ExternalObject.searchFolders.

If you are having difficulty loading your library as an

ExternalObject, set the property

ExternalObject.log to true, then call ExternalObject.search('lib:myLibrary'). This function

performs the search, and the log reports the paths that have been searched to the ExtendScript Toolkit

Console.

Before loading the library, the current folder is temporarily switched to the location of the found

executable file.

X In Mac OS, the current directory is set to the bundle or framework folder for the library.

X In Windows and UNIX, the current directory is set to the folder that contains the library.

ExternalObject constructor

obj = new ExternalObject ("lib:" + filespec, arg1, ...argn);

For example:

var mylib = new ExternalObject( "lib:myLibrary" );

filespec

The specifier "lib:" is case sensitive, and serves as the marker for dynamic libraries.

Concatenate this to the base name of the shared library, with or without an extension.

ExtendScript appends a file extension if necessary, according to the operating system:

X .dll in Windows

X .bundle or .framework in Mac OS (only Mach-O bundles are supported)

X .so in UNIX (except for HP/UX, where the extension is .sl )

The name of the library is case sensitive in UNIX.

arg1...argn

Optional. Any number of arguments to pass to the library’s initialization routine.
