Method Detail

openImp

public void openImp()
             throws java.lang.Exception

Description copied from class: AbstractIterableInput

Subclass implementation of guts of open() method.

Subclasses must implement this to do the actual work required by open(). Feel free to throw exceptions; these are caught inside the open() itself and applied to the exception variable. Thus, you can focus on the actual task instead of paperwork.

Overrides:

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:

parseLine in class LineTextDataRecordSource

Returns:

Throws:

java.lang.Exception

copy

public DataRecordSource copy()

Description copied from class: DataRecordSource

Makes a copy of this DataRecordSource, that you can iterate over separately.

Specified by:

copy in class DataRecordSource

Returns:

copy of this source
