Package io.humble.ferry Description

A collection of classes that ferry objects from Java to native code and back, and manage native memory.

This package contains a variety of classes used by Humble Code to manage communication between Java and and Native Code.

Classes and methods marked "Internal Only" are not meant for usage by anyone outside these libraries. They are public members only because they need to be for other Humble packages to use them -- don't go calling methods on these objects from outside Humble as you can quickly bring down the Java virtual machine if you don't know what you're doing.

Tuning Ferry (And Humble Software) Memory Management

A complicated subject, but if you're ready for it, take a look at the JNIMemoryManager object and start reading.
