Example 3 with OpcUaBinaryStreamDecoder

use of org.eclipse.milo.opcua.stack.core.serialization.OpcUaBinaryStreamDecoder in project milo by eclipse.

the class BsdParserTest method assertRoundTripUsingToString.

/**
 * A weaker version of {@link #assertRoundTrip(String, Object, OpcUaBinaryDataTypeCodec)} for values that don't
 * implement equals and hashcode or values that contain members not implementing equals and  hashcode.
 * <p>
 * Relies on toString() values to be implemented at all levels instead... not great, but since the built-in structs
 * don't implement equals/hashcode it's what we have.
