Method Detail

escapeAllButLastRecordSeparator

public static String escapeAllButLastRecordSeparator(String recordSeparator,
                                     String record)

Insert the default chukwa escape sequence in record before all occurances of recordSeparator except the final one if the final record separator occurs at the end of the record

Parameters:

recordSeparator - The record separator that we are escaping. This is chunk source application specific

record - The string representing the entire record, including the final record delimiter

Returns:

The string with appropriate recordSeparators escaped

escapeAllRecordSeparators

public static String escapeAllRecordSeparators(String recordSeparator,
                               String record)

Insert the default chukwa escape sequence in record before all occurances of recordSeparator. This is assuming that you are not passing the final record separator in with the record, because it would be escaped too.

Parameters:

recordSeparator - The record separator that we are escaping. This is chunk source application specific

record - The string representing the entire record, including the final record delimiter

Returns:

The string with all recordSeparators escaped

recoverRecordSeparators

public static String recoverRecordSeparators(String recordSeparator,
                             String record)
