This method invokes the according property-method of pojoInstance with the given arguments.

Specified by:

invoke in interface PojoPropertyAccessorOneArg

Parameters:

pojoInstance - is the instance of the POJO where to access the property. Has to be an instance of the type from where this accessor was created for.

argument - is the value of the property to set.

Returns:

the result of the invocation. Will be null if void (e.g. regular setter method).

Throws:

ReflectionException - if the underlying accessor caused an error during reflection.
