Detailed Description

A base class for Java peer classes representing a C/C++ object type.

This class declares only non-public members, which enable the JTie runtime to map a Java Wrapper instance to a C/C++ object.

A Java peer class extending Wrapper

  1. must provide a no-arg constructor (may be of any access modifier, but preferred private),
  2. will declare a native method for each C/C++ (member and non-member) function to be mapped to Java, and
  3. ought not to have any non-static fields (i.e., state by its own).

Please, note that JTie provides no guarantees on the association between Wrapper instances and their underlying C/C++ objects. In particular,

  1. multiple Wrapper instances may exist for the same C/C++ object at any time and
  2. a C/C++ object may have been deleted by the application while corresponding Java Wrapper instances still exist (i.e., referential integrity cannot be assumed).
