Package org.graalvm.polyglot

package org.graalvm.polyglot

The GraalVM SDK polyglot API allows to embed Graal languages in Java applications.

To get started quickly create a new Context using Context.create(String...) and then evaluate guest language code using Context.eval(String, CharSequence).

See graalvm.org for more examples on how to use this API.

Since:

19.0
