Method Detail

processLine

public boolean processLine(Line line)

Description copied from interface: LineProcessor

Processes a single line and returns true if this LineProcessor is ready to process more lines. Returning false indicates that the process can be finished because subsequent lines would not change the result anyway.

Parameters:

line - the line to process

Returns:

true if this LineProcessor is ready to process more lines, and false if it does not require any more input lines

finish

public void finish()

Description copied from interface: LineProcessor

Indicates that this line processing task is complete and can finished.

Simple output devices usually perform a flush operation in this method. More complex commands may perform the real operation in this method, for instance write the total count of lines or words to the target file or stream.

reset

public void reset()

Resets the last line, for instance when a new file should be checked.
