Constructor Detail

FileSummary

public FileSummary()

Creates an empty summary.

Method Detail

isEmpty

public boolean isEmpty()

Returns whether this summary contains any non-zero totals.

getObsoleteLNSize

public int getObsoleteLNSize()

Returns the approximate byte size of all obsolete LN entries.

getObsoleteINSize

public int getObsoleteINSize()

Returns the approximate byte size of all obsolete IN entries.

getObsoleteSize

public int getObsoleteSize()
                    throws DatabaseException

Returns an estimate of the total bytes that are obsolete.

Throws:

DatabaseException

getEntriesCounted

public int getEntriesCounted()

Returns the total number of entries counted. This value is guaranted to increase whenever the tracking information about a file changes. It is used a key discriminator for FileSummaryLN records.

getNonObsoleteCount

public int getNonObsoleteCount()

Returns the number of non-obsolete LN and IN entries.

reset

public void reset()

Reset all totals to zero.

add

public void add(FileSummary o)

Add the totals of the given summary object to the totals of this object.

getLogSize

public int getLogSize()

Specified by:

getLogSize in interface LogWritable

Returns:

number of bytes used to store this object.

See Also:

LogWritable.getLogSize()

writeToLog

public void writeToLog(ByteBuffer buf)

Description copied from interface: LogWritable

Serialize this object into the buffer.

Specified by:

writeToLog in interface LogWritable

Parameters:

buf - is the destination buffer

See Also:

LogWritable.writeToLog(java.nio.ByteBuffer)

readFromLog

public void readFromLog(ByteBuffer buf,
                        byte entryTypeVersion)

Description copied from interface: LogReadable

Initialize this object from the data in itemBuf.

Specified by:

readFromLog in interface LogReadable

See Also:

LogReadable.readFromLog(java.nio.ByteBuffer, byte)

dumpLog

public void dumpLog(StringBuffer buf,
                    boolean verbose)

Description copied from interface: LogReadable

Write the object into the string buffer for log dumping. Each object should be dumped without indentation or new lines and should be valid XML.

Specified by:

dumpLog in interface LogReadable

Parameters:

buf - destination string buffer

verbose - if true, dump the full, verbose version

See Also:

LogReadable.dumpLog(java.lang.StringBuffer, boolean)

getTransactionId

public long getTransactionId()

Never called.

Specified by:

getTransactionId in interface LogReadable

Returns:

return the transaction id if this log entry is transactional, 0 otherwise.

See Also:

LogReadable.getTransactionId()

logEntryIsTransactional

public boolean logEntryIsTransactional()

Never called.

Specified by:

logEntryIsTransactional in interface LogReadable

Returns:

true if the LogEntry is a transactional log entry type.

See Also:

LogReadable.logEntryIsTransactional()

toString

public String toString()

Overrides:

toString in class Object
