               Object singleArg,
               Class<T> returnType)

Executes a method defined in Ruby script. This method is used when a Ruby method have only one argument.

Parameters:

receiver - is an instance that will receive this method call

methodName - is a method name to be called

singleArg - is an method argument

returnType - returnType is the type we want it to convert to

Returns:

an instance of requested Java type

callMethod

<T> T callMethod(Object receiver,
               String methodName,
               Object[] args,
               Class<T> returnType)
