generalDatabase.BufferedSQLLogging

Direct Known Subclasses:

QASoundLogging

public abstract class BufferedSQLLogging
extends SQLLogging

Version of SQLLogging which buffers up the data units for a few seconds before writing them so that other parts of PAMguard get a chance to modify them before they go into the database. If a unit is updated AFTER it's been written, it will still get updated in the normal way

This is causing a few issues with the need to subclass

Constructor Details

BufferedSQLLogging

public BufferedSQLLogging(PamDataBlock pamDataBlock,
 int bufferSeconds)

Method Details

flushBuffer

public void flushBuffer()

Flush the buffer, writing everything to the database. This will have to be called explicitly by anything using buffered logging to ensure all data are written, otherwise data may still be in the buffer when the database closes.

logData

public boolean logData(PamConnection con,
 PamDataUnit dataUnit,
 PamDataUnit superDetection)

Description copied from class: SQLLogging

Called when a new PamDataUnit is added to a PamDataBlock to write those data to the database. Functionality moved down to PamCursor so that exact writing method can become database specific if necessary.

Overrides:

logData in class SQLLogging

Parameters:

con - Database Connection

dataUnit - Pamguard Data unit.

superDetection - reference to a super detection so additional cross referencing can be filled

Returns:

true if written and new index of dataUnit retrieved OK

See Also:

• PamDataUnit

reLogData

public boolean reLogData(PamConnection con,
 PamDataUnit dataUnit)

Description copied from class: SQLLogging

Called when an old PamDataUnit is updated. The record is either updated or a new record is written, but cross referenced to the old unit for bookkeeping purposes based on the updatePolicy flag.

Overrides:

reLogData in class SQLLogging

Parameters:

con - Database Connection

dataUnit - Pamguard Data unit.

Returns:

the number of rows written to the database.

See Also:

• PamDataUnit

getBufferSeconds

public int getBufferSeconds()

Returns:

the bufferSeconds

setBufferSeconds

public void setBufferSeconds(int bufferSeconds)

Parameters:

bufferSeconds - the bufferSeconds to set
