The invocation game


java Java Language

LL 20 C

Thursday from 10:00 AM til 10:50 AM

Java 9 expands where invokedynamic is output by the Java compiler, such as for string concatenation, expands the support for building method handle combinator chains, such as for constructing loops, and expands the low-level notion of method handle invocation to methods on VarHandles for enhanced atomic access.

These are core features of the Java platform, that are utilized by the platform and by other frameworks and Java-based languages. They are often the foundations by which future enhancements or experiments are built upon (such as the invocation of native methods as proposed in Project Panama).

This presentation will explain those features in detail, and will then go on to discuss potential future features. The developer will gain a high-level understanding of these features and why they are important for the current and future Java platforms.
