TypedPointer: An instance of a native pointer and its data type

In omegahat/Rffi: Interface to libffi to dynamically invoke arbitrary compiled routines at run-time without compiled bindings

An instance of a native pointer and its data type

Description

This represents an instance of a pointer (not a generic, reusable type). We have the address in memory for the pointer value and also the type of data structure to which it points.

Usage

typedPointer(ptr, elType, obj = new("TypedPointer"))

Arguments

ptr	the value of this pointer, i.e. the location in memory to which it points. This must be an externalptr.
elType	the type of the data to which the pointer ptr points. This must be an instance of FFIType-class
obj	an instance of the class to return. Generally this will not be specified by the caller. It is provided as a parameter so that one can create subclasses and then use this contructor for these.

Value

The function typedPointer returns the updated obj, typically the default class TypedPointer.
