public void openImp()
             throws java.lang.Exception

Description copied from class: AbstractIterableInput

openImp in class LineTextDataRecordSource

Throws:

java.lang.Exception

parseLine

public boolean parseLine(java.lang.String line)
                  throws java.lang.Exception

Description copied from class: LineTextDataRecordSource

Subclasses must implement this. It should read the input string, representing a single line of input, set the currentValues array in DataRecordSource, and return true if successful.

Specified by:
