Method Summary

Methods

Modifier and Type	Method and Description
static int	findMethodIndex(List<Method> methods, MethodScope methodScope, String name, Class<?> returnType, Class<?>[] paramTypes) Searches the supplied array of methods for specific method and returns its index, otherwise returns -1.
static void	findPrefixedInstanceMethods(Method[] methods, String prefix, List<Method> candidates) From the supplied method array, finds but does not remove methods that have the required prefix, and adds to the supplied candidates vector.
static boolean	inScope(Method extendee, MethodScope methodScope)
static void	invoke(List<Method> methods, Object object)
static Method	removeMethod(List<Method> methods, MethodScope methodScope, String name, Class<?> returnType, Class<?>[] paramTypes) Searches the supplied array of methods for specific method and returns it, also removing it from supplied array if found (by setting to null).
static List<Method>	removeMethods(List<Method> methods, MethodScope forClass, String prefix, Class<?> returnType, boolean canBeVoid, int paramCount) Searches the supplied array of methods for all specific methods and returns them, also removing them from supplied array if found.

Method Detail

invoke

public static void invoke(List<Method> methods,
          Object object)

removeMethod

public static Method removeMethod(List<Method> methods,
                  MethodScope methodScope,
                  String name,
                  Class<?> returnType,
                  Class<?>[] paramTypes)

Searches the supplied array of methods for specific method and returns it, also removing it from supplied array if found (by setting to null).

Any methods that do not meet the search criteria are left in the array of methods.

The search algorithm is as specified in findMethodIndex(List, MethodScope, String, Class, Class[]).

findMethodIndex

public static int findMethodIndex(List<Method> methods,
                  MethodScope methodScope,
                  String name,
                  Class<?> returnType,
                  Class<?>[] paramTypes)

Searches the supplied array of methods for specific method and returns its index, otherwise returns -1.

The search algorithm is:

• has the specified prefix
• has the specified return type, or void if canBeVoid is true (but see below)
• has the specified number of parameters

If the returnType is specified as null then the return type is ignored.

inScope

public static boolean inScope(Method extendee,
              MethodScope methodScope)

removeMethods

public static List<Method> removeMethods(List<Method> methods,
                         MethodScope forClass,
                         String prefix,
                         Class<?> returnType,
                         boolean canBeVoid,
                         int paramCount)

Searches the supplied array of methods for all specific methods and returns them, also removing them from supplied array if found.

Any methods that do not meet the search criteria are left in the array of methods.

The search algorithm is:

• has the specified prefix
• has the specified return type, or void if canBeVoid is true (but see below)
• has the specified number of parameters

If the returnType is specified as null then the return type is ignored.

Parameters:

forClass -

name -

returnType -

paramTypes - the set of parameters the method should have, if null then is ignored

Returns:

Method

findPrefixedInstanceMethods

public static void findPrefixedInstanceMethods(Method[] methods,
                               String prefix,
                               List<Method> candidates)

From the supplied method array, finds but does not remove methods that have the required prefix, and adds to the supplied candidates vector.
