Selecting the Java Compat Mapping
Ice provides two distinct Java mappings:
- Java Compat
This mapping is largely source-compatible with prior Ice releases. Although Ice 3.7 no longer supports Java versions prior to Java 8, the "Compat" mapping does not depend on any Java 8-specific language or run-time features. - Java
This is a new mapping introduced in Ice 3.7. It requires Java 8 or later.
This chapter describes the Java Compat mapping.
The Java Compat mapping is provided to make upgrading your code to Ice 3.7 easier, and will not be included in future releases. If you are starting a new project with Ice, please use the Java mapping.
Selecting the Java Compat Mapping
slice2java, the Slice-to-Java translator, generates code for the Java mapping by default. You must specify the --compat option in order to generate code for the Java Compat mapping instead.
