loads a named class from the given library

void close_libraries ()

closes all open libraries.

Detailed Description

name space for the Simple Dynamic Loader.

This namespace groups the types and functionalities assiciated with the Simple Dynamic Loader. These include:

the load_class() function, is the primary access point to the dynamic loader.
the Class class, which defines the interface to dynamically-loaded classes.
the Object class, which defines the interface to the objects of a dynamically-loaded class.
exceptions generated by the access functions.

Function Documentation

Class* load_class ( const string & classname,

const string & libname

) throw (Exception)

loads a named class from the given library
Loads the given library and sets the necessary bindings for the given named class. This method relies on the systems' dynamic loader. In most systems, the dynamic loader uses an environment variable (usually LD_LIBRARY_PATH) to search for dynamic libraries. Unfortunately, different platforms have different dynamic loaders. Please, consult the documentation of your dynamic loader for more details (e.g., dlopen or ld.so).

Parameters:

classname name of the class to load

libname name of the shared-object library file

Exceptions:

Exception when the library can not be loaded or when the binding function can not be found in the library file.
