Method Summary

static void	findPrefixedInstanceMethods(java.lang.reflect.Method[] methods, java.lang.String prefix, java.util.List<java.lang.reflect.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(MethodScope methodScope, java.lang.reflect.Method method)
static java.lang.reflect.Method	removeMethod(java.lang.reflect.Method[] methods, MethodScope methodScope, java.lang.String name, java.lang.Class<?> returnType, java.lang.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 java.util.List<java.lang.reflect.Method>	removeMethods(java.lang.reflect.Method[] methods, MethodScope forClass, java.lang.String prefix, java.lang.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

removeMethod

public static java.lang.reflect.Method removeMethod(java.lang.reflect.Method[] methods,
                                                    MethodScope methodScope,
                                                    java.lang.String name,
                                                    java.lang.Class<?> returnType,
                                                    java.lang.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:

• 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

inScope

public static boolean inScope(MethodScope methodScope,
                              java.lang.reflect.Method method)

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
