Class PrefixMethodInvocationUtil
Interceptors that made use of this class are:
- DefaultWorkflowInterceptor
- PrepareInterceptor
In DefaultWorkflowInterceptor
applies only when action implements Validateable
- if the action class have validate{MethodName}(), it will be invoked
- else if the action class have validateDo{MethodName}(), it will be invoked
- no matter if 1] or 2] is performed, if alwaysInvokeValidate property of the interceptor is "true" (which is by default "true"), validate() will be invoked.
In PrepareInterceptor
Applies only when action implements Preparable
- if the action class have prepare{MethodName}(), it will be invoked
- else if the action class have prepareDo(MethodName()}(), it will be invoked
- no matter if 1] or 2] is performed, if alwaysinvokePrepare property of the interceptor is "true" (which is by default "true"), prepare() will be invoked.

Method Details- 
invokePrefixMethodpublic static void invokePrefixMethod(ActionInvocation actionInvocation, String[] prefixes) throws InvocationTargetException, IllegalAccessException This method will prefix actionInvocation'sActionProxy'smethodwithprefixesbefore invoking the prefixed method. Order of theprefixesis important, as this method will return once a prefixed method is found in the action class.For example, with invokePrefixMethod(actionInvocation, new String[] { "prepare", "prepareDo" });Assuming actionInvocation.getProxy(),getMethod()returns "submit", the order of invocation would be as follows:-- prepareSubmit()
- prepareDoSubmit()
 If prepareSubmit()exists, it will be invoked and this method will return,prepareDoSubmit()will NOT be invoked.On the other hand, if prepareDoSubmit()does not exists, andprepareDoSubmit()exists, it will be invoked.If none of those two methods exists, nothing will be invoked. - Parameters:
- actionInvocation- the action invocation
- prefixes- prefixes for method names
- Throws:
- InvocationTargetException- is thrown if invocation of a method failed.
- IllegalAccessException- is thrown if invocation of a method failed.
 
- 
getPrefixedMethodThis method returns aMethodinaction. The method returned is found by searching for method inactionwhose method name is equals to the result of appending eachprefixestomethodName. Only the first method found will be returned, hence the order ofprefixesis important. If none is found this method will return null.- Parameters:
- prefixes- the prefixes to prefix the- methodName
- methodName- the method name to be prefixed with- prefixes
- action- the action class of which the prefixed method is to be search for.
- Returns:
- a Methodif one is found, else null.
 
- 
capitalizeMethodNameThis method capitalized the first character of methodName.
 eg.capitalizeMethodName("someMethod");will return"SomeMethod".- Parameters:
- methodName- the method name
- Returns:
- capitalized method name
