Constructor Detail

SnapshotValue

public SnapshotValue(Map prop)
Constructs a new snapshot value.

Method Detail

registerParameter

public void registerParameter(Parameter watch)
Registers the parameter. First, checks if the parameter handed over is a value. If so, proceed with the parental method.

Specified by:
registerParameter in interface ParameterDepending
Overrides:
registerParameter in class SnapshotParameter

getValue

public Number getValue()
Casts the last value snapshot to a number. Returns null if conversion fails.

Specified by:
