// .NAME vtkProgrammableSource - generate source dataset via a user-specified function
// .SECTION Description
// vtkProgrammableSource is a source object that is programmable by the
// user. To use this object, you must specify a function that creates the
// output. It is possible to generate an output dataset of any (concrete)
// type; it is up to the function to properly initialize and define the
// output. Typically, you use one of the methods to get a concrete output
// type (e.g., GetPolyDataOutput() or GetStructuredPointsOutput()), and
// then manipulate the output in the user-specified function.
//
// Example use of this include writing a function to read a data file or
// interface to another system. (You might want to do this in favor of
// deriving a new class.) Another important use of this class is that it
// allows users of interpreters (e.g., Tcl or Java) the ability to write
// source objects without having to recompile C++ code or generate new
// libraries.

// Description:
// Signature definition for programmable method callbacks. Methods passed
// to SetExecuteMethod, SetExecuteMethodArgDelete or
// SetRequestInformationMethod must conform to this signature.
// The presence of this typedef is useful for reference and for external
// analysis tools, but it cannot be used in the method signatures in these
// header files themselves because it prevents the internal VTK wrapper
// generators from wrapping these methods.
typedef void (*ProgrammableMethodCallbackType)(void *arg);
// Description:
// Specify the function to use to generate the source data. Note
// that the function takes a single (void *) argument.
void SetExecuteMethod(void (*f)(void *), void *arg);
// Description:
// Set the arg delete method. This is used to free user memory.
void SetExecuteMethodArgDelete(void (*f)(void *));
// Description:
// Specify the function to use to fill in information about the source data.
void SetRequestInformationMethod(void (*f)(void *));
// Description:
// Get the output as a concrete type. This method is typically used by the
// writer of the source function to get the output as a particular type
// (i.e., it essentially does type casting). It is the users responsibility
// to know the correct type of the output data.
