Class PrefixMethodInvocationUtil
java.lang.Object
 com.opensymphony.xwork.interceptor.PrefixMethodInvocationUtil
public class PrefixMethodInvocationUtil - extends Object
A utility class for invoking prefixed methods in action class.
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.

PrefixMethodInvocationUtil
public PrefixMethodInvocationUtil()
invokePrefixMethod
public static void invokePrefixMethod(ActionInvocation actionInvocation,
String[] prefixes)
throws InvocationTargetException,
IllegalAccessException
- This method will prefix
actionInvocation's ActionProxy's
method with prefixes before invoking the prefixed method.
Order of the prefixes is 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, and
prepareDoSubmit() exists, it will be invoked.
If none of those two methods exists, nothing will be invoked.
- Parameters:
actionInvocation - prefixes -
- Throws:
InvocationTargetException
IllegalAccessException
getPrefixedMethod
public static Method getPrefixedMethod(String[] prefixes,
String methodName,
Object action)
- This method returns a
Method in action. The method
returned is found by searching for method in action whose method name
is equals to the result of appending each prefixes
to methodName. Only the first method found will be returned, hence
the order of prefixes is important. If none is found this method
will return null.
- Parameters:
prefixes - the prefixes to prefix the methodNamemethodName - the method name to be prefixed with prefixesaction - the action class of which the prefixed method is to be search for.
- Returns:
- a
Method if one is found, else null.
capitalizeMethodName
public static String capitalizeMethodName(String methodName)
- This method capitalized the first character of
methodName.
eg.
capitalizeMethodName("someMethod");
will return "SomeMethod".
- Parameters:
methodName -
- Returns:
