Method Detail

clearAll

public void clearAll()

Description copied from class: PamDataBlock

Clears all PamDataUnits from memory

In viewer mode, data are also re-saved.

Overrides:

clearAll in class PamDataBlock<StreamerDataUnit>

loadViewerData

public boolean loadViewerData(long dataStart,
                     long dataEnd,
                     ViewLoadObserver loadObserver)

Description copied from class: PamDataBlock

Instruction from the viewer scroll manager to load new data.

Overrides:

loadViewerData in class PamDataBlock<StreamerDataUnit>

Parameters:

dataStart - data start time in millis

dataEnd - data end time in millis.

getPreceedingUnit

public StreamerDataUnit getPreceedingUnit(long startTime,
                                 int channelMap)

Description copied from class: PamDataBlock

Simple function to find the data unit at or before the given start time that has a given channel bitmap

Overrides:

getPreceedingUnit in class PamDataBlock<StreamerDataUnit>

Parameters:

startTime - search time in milliseconds

channelMap - Channel bitmap

Returns:

data unit at or following the given time.

getNumRequiredBeforeLoadTime

public int getNumRequiredBeforeLoadTime()

Description copied from class: PamDataBlock

Get the number of pam data units that are required prior to the load times that get sent to loadViewerData. This can be used for things like hydrophone data where it may be necessary to load up a few earlier points to complete a trackline, etc.

Overrides:

getNumRequiredBeforeLoadTime in class PamDataBlock<StreamerDataUnit>

Returns:

number of units required.

getShouldLog

public boolean getShouldLog(PamDataUnit pamDataUnit)

Description copied from class: PamDataBlock

Should log the data unit to the database ?

Overrides:

getShouldLog in class PamDataBlock<StreamerDataUnit>

Parameters:

pamDataUnit - dataunit to consider

Returns:

true if data should be logged.
