Finds the method named in the BaseMethod.m_methodName field in the given targetClass. If the target class has no acceptable method the class hierarchy is traversed until a method is found or the root of the class hierarchy is reached without finding a method.

Specified by:

doFindMethod in class BaseMethod<BindParameters,List<org.apache.felix.scr.impl.inject.BindMethod.ParamType>>

Parameters:

targetClass - The class in which to look for the method

acceptPrivate - true if private methods should be considered.

acceptPackage - true if package private methods should be considered.

logger -

Returns:

The requested method or null if no acceptable method can be found in the target class or any super class.

Throws:

InvocationTargetException - If an unexpected Throwable is caught trying to find the requested method.
