Example 1 with JNIUtil.createHSString

use of org.graalvm.jniutils.JNIUtil.createHSString in project graal by oracle.

the class TruffleToLibGraalEntryPoints method getNodeTypes.

    JNIMethodScope scope = LibGraalUtil.openScope(TruffleToLibGraalEntryPoints.class, GetNodeTypes, env);
    try (JNIMethodScope s = scope) {
        GraphInfo orig = LibGraalObjectHandles.resolve(handle, GraphInfo.class);
        String[] nodeTypes = orig.getNodeTypes(simpleNames);
        JClass componentType = FromLibGraalCalls.getJNIClass(env, String.class);
