Method Details

addPamData

public void addPamData(Tunit pamDataUnit)

Description copied from class: PamDataBlock

Adds a new PamDataUnit to the PamDataBlock. When the data unit is added, PamObservers that have subscribed to the block will be notified.
If the data unit already has a UID, it will be left as is.

Overrides:

addPamData in class PamDataBlock<Tunit extends PamDataUnit>

Parameters:

pamDataUnit - Reference to a PamDataUnit

removeOldUnitsT

protected int removeOldUnitsT(long currentTimeMS)

Description copied from class: PamDataBlock

Removes olderPamDataUnits from memory, starting at the first unit and continuing until if finds one with data coming earlier than the given time in milliseconds.

If the data are acoustic, it tries to find the data source and looks to see how much data has been placed in the source data unit and does the calculation in samples.

Overrides:

removeOldUnitsT in class PamDataBlock<Tunit extends PamDataUnit>

Parameters:

currentTimeMS - Time in milliseconds of the first data which must be kept

Returns:

the number of units removed

removeOldUnitsS

protected int removeOldUnitsS(long mastrClockSample)

Overrides:

removeOldUnitsS in class PamDataBlock<Tunit extends PamDataUnit>

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<Tunit extends PamDataUnit>
