Hence we have this class. * * <p> * We expect the user to set a few properties and then use that same * setting to make a bunch of invocations. So we'd like to take some hit * when the user actually sets a property to do some computation, * then use that computed value during a method invocation again and again. * * <p> * For this goal, we use {@link com.sun.xml.internal.ws.api.PropertySet} and implement some properties * as virtual properties backed by methods. This allows us to do the computation * in the setter, and store it in a field. * * <p> * These fields are used by {@link Stub#process} to populate a {@link Packet}. * * <h2>How it works? * <p> * For better performance, we wan't use strongly typed field as much as possible * to avoid reflection and unnecessary collection iterations; * * Using {@link com.oracle.webservices.internal.api.message.BasePropertySet.MapView} implementation allows client to use {@link Map} interface * in a way that all the strongly typed properties are reflected to the fields * right away. Any additional (extending) properties can be added by client as well; * those would be processed using iterating the {@link MapView} and their processing, * of course, would be slower. * <p> * The previous implementation with fallback mode has been removed to simplify * the code and remove the bugs. * * @author Kohsuke Kawaguchi */ @SuppressWarnings({"SuspiciousMethodCalls"}) public final class RequestContext extends BaseDistributedPropertySet { private static final Logger LOGGER = Logger.getLogger(RequestContext.class.getName()); /** * The default value to be use for {@link #contentNegotiation} obtained * from a system property. * <p> * This enables content negotiation to be easily switched on by setting * a system property on the command line for testing purposes tests. */ private static ContentNegotiation defaultContentNegotiation = ContentNegotiation.obtainFromSystemProperty(); /** * @deprecated */ public void addSatellite(@NotNull com.sun.xml.internal.ws.api.PropertySet satellite) { super.addSatellite(satellite); } /** * The endpoint address to which this message is sent to. * * <p> * This is the actual data store for {@link BindingProvider#ENDPOINT_ADDRESS_PROPERTY}. */ private @NotNull EndpointAddress endpointAddress; /** * Creates {@link BindingProvider#ENDPOINT_ADDRESS_PROPERTY} view * on top of {@link #endpointAddress}. * * @deprecated * always access {@link #endpointAddress}. */ @Property(ENDPOINT_ADDRESS_PROPERTY) public String getEndPointAddressString() { return endpointAddress != null ? endpointAddress.toString() : null; } public void setEndPointAddressString(String s) { if (s == null) { throw new IllegalArgumentException(); } else { this.endpointAddress = EndpointAddress.create(s); } } public void setEndpointAddress(@NotNull EndpointAddress epa) { this.endpointAddress = epa; } public @NotNull EndpointAddress getEndpointAddress() { return endpointAddress; } /** * The value of {@link ContentNegotiation#PROPERTY} * property. */ public ContentNegotiation contentNegotiation = defaultContentNegotiation; @Property(ContentNegotiation.PROPERTY) public String getContentNegotiationString() { return contentNegotiation.toString(); } public void setContentNegotiationString(String s) { if (s == null) { contentNegotiation = ContentNegotiation.none; } else { try { contentNegotiation = ContentNegotiation.valueOf(s); } catch (IllegalArgumentException e) { // If the value is not recognized default to none contentNegotiation = ContentNegotiation.none; } } } /** * The value of the SOAPAction header associated with the message. * * <p> * For outgoing messages, the transport may sends out this value. * If this field is null, the transport may choose to send <tt>"" * (quoted empty string.) * * For incoming messages, the transport will set this field. * If the incoming message did not contain the SOAPAction header, * the transport sets this field to null. * * <p> * If the value is non-null, it must be always in the quoted form. * The value can be null. * * <p> * Note that the way the transport sends this value out depends on * transport and SOAP version. * * For HTTP transport and SOAP 1.1, BP requires that SOAPAction * header is present (See {@BP R2744} and {@BP R2745}.)
