Constructor Detail

ReflectAction

public ReflectAction(Class c,
                     String methodName)

ReflectAction constructor.

Parameters:

c - class containing method

methodName - name of method to reflect

ReflectAction

public ReflectAction(Class c,
                     String methodName,
                     Class[] parameterTypes)

ReflectMethodRowAction constructor.

Parameters:

c - class containing method

methodName - name of method to reflect on the Row

parameterTypes - array of class types for method parameters

ReflectAction

public ReflectAction(String methodName)

ReflectMethodRowAction constructor.

Parameters:

methodName - name of method to reflect on the Row

ReflectAction

public ReflectAction(String methodName,
                     Class[] parameterTypes)

ReflectMethodRowAction constructor.

Parameters:

methodName - name of method to reflect on the Row

Method Detail

getMethodClass

public Class getMethodClass()

Gets the Class containing the method to reflect.

Returns:

class contianing method

getMethodName

public String getMethodName()

Gets the name of the method this action should reflect on a given Row.

Returns:

name of method to reflect on Row.

getParameterTypes

public Class[] getParameterTypes()

Gets the parameter types classes to use when reflecting on a Row's method..

Returns:

parameter types.

handleAction

public Object handleAction(Object o)
                    throws InvocationTargetException

Refects this action's method on the given object. If the method to be used for reflection requires parameters, then handleAction(Object, Object[]) should be used.

Specified by:

handleAction in class AbstractAction

Parameters:

o - Object to perform the action on

InvocationTargetException

handleAction

public Object handleAction(Object o,
                           Object[] args)
                    throws InvocationTargetException

Uses java reflection to invoke this action's method on the given Object. No Object is required if invoking a static method on an Object, provided a Class was specified during this action's instance creation.

Parameters:

o - Object to reflect method on

InvocationTargetException

setMethodClass

public void setMethodClass(Class c)

Sets the Class contianing the method to reflect.

setMethodName

public void setMethodName(String methodName)

Sets the name of the method this action should reflect on a given Row.

Parameters:

methodName - name of method to reflect on Row.

setParameterTypes

public void setParameterTypes(Class[] parameterTypes)

Sets the parameter types the method this action should use when reflecting on a given Row.

Parameters:

parameterTypes - array of classes for method.
