Hi, In the previous postings to the list, i had a problem reading ASCII file in Kepler but after getting some idea from list it solved. Now i write a new actor that substract the specified column of the multi column ASCII file after reading it. The code is attached to mail as 'ArrayColumn.java'. It gets two parameter; first one is number of column in ASCII file and second one is index of the first data (must be less than number of column !!!). So using theses values it ouputs the defined column of the array.
My problem is controlling data type of the output port. It gets the input from 'String Splitter' actor (it is used after reading ASCII file with \s regular expression) and results is the same data type with input (ArrayType(String)). So, i need to convert them into float or other numeric data types to calculate the maximum, minimum or average. How can i control the output port data type automatically? Is it neccecary to fix it inside of the code such as type casting? Any idea must be very helpful.
