/** \class GenericStruct This class maintains a pointer to some arbitrary
|
|
* object (which can be any thing). The plugin is responsible for supplying
|
|
* functions for manipulating such structs/classes/arrays. The Yacas core
|
|
* then needs to know nothing about the internals of such a struct.
|
|
*
|
|
* The struct is represented by a void pointer to the struct, a pointer
|
|
* to a function that can clean up the struct (used when automatically
|
|
* deleting the object), and a pointer to a text string representing the
|
|
* type of the object (useful for testing if the type passed as an argument
|
|
* to a function is correct).
