@Deprecated
public class LogReader
extends Object

LogReader class provides mechanism to read a log file to the caller. It does the authorization check, reads line from the file, applies the query (if any), collects most recent records, sorts the records, and returns the result in a two dimensional String. Where columns in the the first row, i.e. 0th row, always holds the header info (field names) present in the ELF formatted file. Other rows hold the value present under those columns.

Method Detail

getSizeUnits

public static int getSizeUnits()
                        throws Exception

Deprecated.

Returns the units (LogConstants.NUM_BYTES or LogConstants.NUM_RECORDS) that applies to the value returned by getSize(logName).

Returns:

the units applying to the return value of getSize(logName), LogConstants.NUM_BYTES (in the case of File logging), or LogConstants.NUM_RECORDS (in the case of DB logging).

Throws:

Exception - if unrecoverable problem occurs, that is beyond its control.

getSize

public static long getSize(String logName)
                    throws IOException,
                           Exception

Deprecated.

Returns the number of LogRecords in the specified table in the DB. In the case where logging is to a file, the number of bytes in the specified file is returned. Use getSizeUnits() to get which units apply.

Parameters:

logName - the name of the Table or File.

Returns:

the number of LogRecords (in the DB table), or number of bytes (in the file).

Throws:

IOException - if file does not exist.

Exception - if unrecoverable problem occurs, that is beyond its control.

getLogNames

public static Set getLogNames()

Deprecated.

Returns the names of the Log Files or Tables. The Set of names is what is found in the directory or DB, filtered through a default list of names. Thus, log files or tables with custom names will not be included. This does not preclude querying those log files or tables with custom names.

Returns:

the Log File/Table names in a Set.

getLogFields

public static ArrayList getLogFields()

Deprecated.

Returns the names of the Log Fields that are selected for logging in the Logging Service template, plus the mandatory "time" and "Data" fields.

Returns:

the Field/Column names in an ArrayList.

IOException - if interrupted or failed to do I/O.

NoSuchFieldException - if invalid field has been specified.

IllegalArgumentException - when inappropriate argument specified.

RuntimeException - when it has been caught in any phase.

Exception - if unrecoverable problem occurs, that is beyond its control.
