Method Detail

• public static boolean accessibleToConstructor(Class at, Constructor constructor)

• public static Object asPrimitiveArray(List list, Class parameterType)

  Parameters:

  list - the original list

  parameterType - the resulting array type

  Returns:

  the constructed array

• public static Object[] asWrapperArray(Object parameters, Class componentType)

• public static long calculateParameterDistance(Class[] arguments, ParameterTypes pt)

• @Deprecated
  public static String capitalize(String property)

  deprecated:

  Use BeanUtils.capitalize instead

• public static Class[] castArgumentsToClassArray(Object[] argTypes)

• public static Object chooseEmptyMethodParams(FastArray methods)

  Parameters:

  methods - the methods to choose from

  Returns:

  the method with 1 parameter which takes the most general type of object (e.g. Object)

• @Deprecated
  public static Object chooseMostGeneralMethodWith1NullParam(FastArray methods)

  Warning: this method does not choose properly if multiple methods with the same distance are encountered

  deprecated:

  Parameters:

  methods - the methods to choose from

  Returns:

  the method with 1 parameter which takes the most general type of object (e.g. Object) ignoring primitive types

• public static boolean containsMatchingMethod(List list, MetaMethod method)

  Parameters:

  list - a list of MetaMethods

  method - the MetaMethod of interest

  Returns:

  true if a method of the same matching prototype was found in the list

• public static String convertPropertyName(String prop)

  Converts a String into a standard property name.

  Parameters:

  prop - the original name

  Returns:

  the converted name

• public static Class[] convertToTypeArray(Object[] args)

  param instance array to the type array

  Parameters:

  args - the arguments

  Returns:

  the types of the arguments

• public static GroovyRuntimeException createExceptionText(String init, MetaMethod method, Object object, Object[] args, Throwable reason, boolean setReason)

• public static void doSetMetaClass(Object self, MetaClass mc)

  Sets the meta class for an object, by delegating to the appropriate DefaultGroovyMethods helper method. This method was introduced as a breaking change in 2.0 to solve rare cases of stack overflow. See GROOVY-5285. The method is named doSetMetaClass in order to prevent misusages. Do not use this method directly unless you know what you do.

  Parameters:

  self - the object for which to set the meta class

  mc - the metaclass

• public static Closure getMethodPointer(Object object, String methodName)

  Returns a callable object for the given method name on the object. The object acts like a Closure in that it can be called, like a closure and passed around - though really its a method pointer, not a closure per se.

  Parameters:

  object - the object containing the method

  methodName - the method of interest

  Returns:

  the resulting closure-like method pointer
