Example 1 with InvalidBufferOffsetException

use of com.oracle.truffle.api.interop.InvalidBufferOffsetException in project graal by oracle.

the class PolyglotHostObjectPartialEvaluationTest method readBufferByte.

@Test
public void readBufferByte() {
    for (final Buffer buffer : ValueAPITest.makeTestBuffers()) {
        getContext().initialize(ProxyLanguage.ID);
        final Object bufferHostObject = LanguageContext.get(null).getEnv().asGuestValue(buffer);
        final RootNode node = new RootNode(null) {

            @Child
            InteropLibrary interop = InteropLibrary.getFactory().createDispatched(1);
