Method Detail

logRecRead

String[][] logRecRead(String tableName,
                      LogQuery qry,
                      LogManager logMgr,
                      boolean sourceData)
               throws IOException,
                      NoSuchFieldException,
                      IllegalArgumentException,
                      RuntimeException,
                      SQLException,
                      Exception

LogReader calls this 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:

tableName - db table name

qry - is user specified qury chriteria with sorting requirement

logMgr - the log manager associated with this handler

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.

SQLException - if it fails to process sql query.

Exception - if it fails any of operation.

logRecRead

String[][] logRecRead(Set tableNames,
                      LogQuery qry,

                      boolean sourceData)
               throws IOException,
                      NoSuchFieldException,
                      IllegalArgumentException,
                      RuntimeException,
