asWrapperArray
- 
asPrimitiveArray- Parameters:
- list- the original list
- parameterType- the resulting array type
- Returns:
- the constructed array
 
- 
calculateParameterDistance
- 
capitalizeDeprecated.Use BeanUtils.capitalize instead
- 
chooseEmptyMethodParams- Parameters:
- methods- the methods to choose from
- Returns:
- the method with 1 parameter which takes the most general type of object (e.g. Object)
 
- 
chooseMostGeneralMethodWith1NullParamDeprecated.Warning: this method does not choose properly if multiple methods with the same distance are encountered- 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
 
- 
containsMatchingMethod- 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
 
- 
convertToTypeArrayparam instance array to the type array- Parameters:
- args- the arguments
- Returns:
- the types of the arguments

getMethodPointerReturns 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 it's 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

doSetMetaClassSets the metaclass for an object, by delegating to the appropriateDefaultGroovyMethodshelper 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 misuses. Do not use this method directly unless you know what you do.- Parameters:
- self- the object for which to set the metaclass
- mc- the metaclass
 
- 
convertPropertyNameConverts a String into a standard property name.- Parameters:
- prop- the original name
- Returns:
- the converted name
