Method Summary

boolean	isEndOfRecord(String line) Signal the end of a record based on the content of a line, being the latest line read from an input source.
String	postProcess(String record) Give the policy a chance to post-process a complete record, e.g. remove a suffix.
String	preProcess(String record) Pre-process a record before another line is appended, in the case of a multi-line record.

Method Detail

isEndOfRecord

boolean isEndOfRecord(String line)

Signal the end of a record based on the content of a line, being the latest line read from an input source. The input is what you would expect from BufferedReader.readLine() - i.e. no line separator character at the end. But it might have line separators embedded in it.

Parameters:

line - a String without a newline character at the end.

Returns:

true if this line is the end of a record.

postProcess

String postProcess(String record)

Give the policy a chance to post-process a complete record, e.g. remove a suffix.

Parameters:

record - the complete record.

Returns:

a modified version of the record if desired.

preProcess

String preProcess(String record)

Pre-process a record before another line is appended, in the case of a multi-line record. Can be used to remove a prefix or line-continuation marker. If a record is a single line this callback is not used (but postProcess(String) will be).

Parameters:

record - the current record.

Returns:

the line as it should be appended to a record.
