Method Detail

measurementChanged

void measurementChanged(MeasurementService source,
                        java.lang.Object timestamp,
                        ChannelService channel,
                        java.lang.Object newValue,
                        java.lang.Object oldValue)

This method is fired to all Listeners each time the value of the measurement changes. Since other notifications are blocked until this method returns, implementors of this method should:

• Not cause the device or transport to be blocked (e.g. calling read on a measurement).
• Handle this call quickly and return.

Parameters:

source - The source (MeasurementService) parameter.

timestamp - The time stamp (Object) parameter.

channel - The channel (ChannelService) parameter.

newValue - The new value (Object) parameter.

oldValue - The old value (Object) parameter.
