Constructors Summary

private Invocation(Method method, XmlStreamWriterMethodType type, Object[] args) Private constructor of the class used in the {@link createInvocation(Method, Object[])} factory method. param method method represented by the new {@link Invocation} instance param type method type represented by the new {@link Invocation} instance param args invocation arguments to be passed to the method when {@link #execute()} method is invoked on the {@link Invocation} instance. see XmlStreamWriterMethodType this.method = method; this.arguments = args; this.methodType = type;

Methods Summary
public java.lang.String	argsToString() Method returns {@link String} representation of arguments stored in the {@link Invocation} instance. return {@link String} representation of arguments stored in the {@link Invocation} instance. if (argsString == null) { List<Object> argList = null; if (arguments != null && arguments.length > 0) { if (arguments.length == 3 && "writeCharacters".equals(method.getName())) { argList = new ArrayList<Object>(3); argList.add(new String((char[]) arguments[0])); argList.add(arguments[1]); argList.add(arguments[2]); } else { argList = Arrays.asList(arguments); } } argsString = (argList == null) ? "no arguments" : argList.toString(); } return argsString;
public static com.sun.xml.ws.policy.jaxws.xmlstreamwriter.Invocation	createInvocation(java.lang.reflect.Method method, java.lang.Object[] args) Factory method that creates {@link Invocation} instance according to input arguments param method method represented by the {@link Invocation} instance returned as a result of this factory method call param args invocation arguments to be passed to the method when {@link #execute()} method is invoked on the {@link Invocation} instance. return the {@link Invocation} instance representing invocation of method defined by value of {@code method} argument. final Object[] arguments; final XmlStreamWriterMethodType methodType = XmlStreamWriterMethodType.getMethodType(method.getName()); if (methodType == WRITE_CHARACTERS && args.length == 3) { final Integer start = (Integer) args[1]; final Integer length = (Integer) args[2]; final char[] charArrayCopy = new char[length.intValue()]; System.arraycopy(args[0], start, charArrayCopy, 0, length); arguments = new Object[3]; arguments[0] = charArrayCopy; arguments[1] = Integer.valueOf(0); arguments[2] = length; } else { arguments = args; } return new Invocation(method, methodType, arguments);
public java.lang.Object	execute(javax.xml.stream.XMLStreamWriter target) Executes the method on {@code target} {@code XMLStreamWriter} instance. return execution result. exception IllegalAccessException see {@link java.lang.reflect.Method.invoke(Object, Object[]) Method.invoke()}. exception IllegalArgumentException see {@link java.lang.reflect.Method.invoke(Object, Object[]) Method.invoke()}. exception InvocationTargetException see {@link java.lang.reflect.Method.invoke(Object, Object[]) Method.invoke()}. exception NullPointerException see {@link java.lang.reflect.Method.invoke(Object, Object[]) Method.invoke()}. exception ExceptionInInitializerError see {@link java.lang.reflect.Method.invoke(Object, Object[]) Method.invoke()}. return method.invoke(target, arguments);
public java.lang.Object	getArgument(int index) Returns single invocation argument for this {@link Invocation} instance that is stored in the invocation arguments array at position determined by {@code index} argument. return single invocation argument for this {@link Invocation} instance at position determined by {@code index} argument throws ArrayIndexOutOfBoundsException if there are no arguments in the array or if the index parameter is out of bounds of invocation arguments array if (arguments == null) { throw LOGGER.logSevereException(new ArrayIndexOutOfBoundsException(WSP_1052_NO_ARGUMENTS_IN_INVOCATION(this.toString()))); } return arguments[index];
public int	getArgumentsCount() Returns information about the number of arguments stored in this {@link Invocation} instance return number of arguments stored in this {@link Invocation} instance return (arguments == null) ? 0 : arguments.length;
public java.lang.String	getMethodName() Returns information about the name of the method represented by this {@link Invocation} instance return method name represented by this {@link Invocation} instance return method.getName();
public XmlStreamWriterMethodType	getMethodType() Returns information about the type of the method represented by this {@link Invocation} instance return method type represented by this {@link Invocation} instance see XmlStreamWriterMethodType return methodType;
public java.lang.String	toString() Method returns {@link String} representation of the {@link Invocation} instance. return {@link String} representation of the {@link Invocation} instance. final StringBuffer retValue = new StringBuffer(30); retValue.append("invocation { method='").append(method.getName()).append("', args=").append(argsToString()); retValue.append('}"); return retValue.toString();
