Method Detail

logRecRead

String[][] logRecRead(String fileName,
                      LogQuery qry,
                      boolean sourceData)
               throws IOException,
                      NoSuchFieldException,
                      IllegalArgumentException,
                      RuntimeException,
                      Exception

LogReader calls this method method. It collects header, records, applies query (if any), sorts (if asked) the records on field, checks the max records to return, collects all the recods and returns.

Parameters:

fileName - is complete filename with path

qry - is user specified qury chriteria with sorting requirement

sourceData - it specifies whether return data should be original data received by logger (source) or formatted data as in file.

Returns:

all the matched records with query

Throws:

IOException - if it fails to read log records.

NoSuchFieldException - if it fails to retrieve the name of field.

IllegalArgumentException - if query has wrong value.

RuntimeException - if it fails to retrieve log record.

Exception - if it fails any of operation.

               throws IOException,
                      NoSuchFieldException,
